What is  Pythagorean Theorem?

The Pythagorean theorem is a basic mathematical theorem that describes the connection between the sides of a right triangle. It asserts that the square of the length of the hypotenuse (the side opposite the right angle) in a right triangle is equal to the sum of the squares of the other two sides.

The Pythagorean theorem can be stated mathematically as:

[tex]C^2 = A^2 + B^2[/tex]

where "C" indicates the length of the hypotenuse and "A" and "B" represent the lengths of the other two sides of the right triangle.

In this scenario, the ladder is the hypotenuse of a right-angled triangle, with the wall constituting one side and the distance between the bottom of the ladder and the wall forming the other.

Given,

Length of the ladder (hypotenuse) = 15 feet

Height of the ladder on the wall (one side) = 13 feet

Let's call the distance between the bottom of the ladder and the wall "x" feet.

Using Pythagorean theorem ,

[tex]15^2 = 13^2 + x^2[/tex]

225 = 169 + [tex]x^{2}[/tex]

[tex]x^{2}[/tex] = 225 - 169

[tex]x^{2}[/tex] = 56

x = [tex]\sqrt{56}[/tex]   (taking the square root of both sides)

x [tex]$\approx$[/tex] 7.5 feet

As a result, the distance between the bottom of the ladder and the wall is around 7.5 feet (rounded to the nearest tenth).

why would you use a trigonometric function to set-up an application problem instead of a non-trigonometric function

Answers

Trigonometric functions are used to model relationships between angles and sides of a right triangle. They are particularly useful in solving problems that involve angles, distances, heights, and lengths that are difficult to measure directly.

For example, consider a problem that involves finding the height of a building. By measuring the length of the shadow cast by the building at a particular time of day, the angle of the sun's rays can be calculated using trigonometry. Once the angle is known, the height of the building can be determined using the tangent function.

In contrast, a non-trigonometric function may not be able to model the relationship between the given quantities in such problems, and may not provide an accurate solution. Therefore, when a problem involves angles or distances that are not directly measurable, trigonometric functions are typically the best tool for setting up and solving the problem.

When a researcher uses the Pearson product-moment correlation, two highly correlated variables will appear on a scatter diagram as a tightly clustered group of points that form a linear pattern.

The scatter diagram is a visual representation of the correlation between two variables, where one variable is plotted on the x-axis, and the other variable is plotted on the y-axis. If the two variables have a high positive correlation, then the points on the scatter diagram will form a cluster that slopes upwards to the right.

On the other hand, if the two variables have a high negative correlation, then the points will form a cluster that slopes downwards to the right. The tighter the cluster of points, the higher the correlation between the variables.

Find the avatar rate of change f(x)=3√x-1 +2; 9 ≤ x ≤ 65

Answers

Answer: To find the average rate of change of the function f(x) over the interval [9, 65], we can use the formula:

average rate of change = (f(b) - f(a)) / (b - a)

where a = 9, b = 65, f(a) = f(9) = 3√8 + 2, and f(b) = f(65) = 3√64 + 2.

Plugging in these values, we get:

So, 135 km/h is approximately equal to 37.5 m/s.

the population of weights for men attending a local health club is normally distributed with a mean of 166-lbs and a standard deviation of 26-lbs. an elevator in the health club is limited to 33 occupants, but it will be overloaded if the total weight is in excess of 5940-lbs. assume that there are 33 men in the elevator. what is the average weight beyond which the elevator would be considered overloaded? average weight

Answers

This means that if the average weight of the men in the elevator is more than 180 lbs, the elevator would be overloaded.

To determine the average weight beyond which the elevator would be considered overloaded, we can follow these steps:
Find the total weight limit for 33 occupants: 5940 lbs.

Divide the total weight limit by the number of occupants to find the average weight per person: 5940 / 33 = 180 lbs.
Now, we need to find the difference between the average weight per person (180 lbs) and the mean weight of the population (166 lbs): 180 - 166 = 14 lbs.
Since we have the difference and the standard deviation (26 lbs), we can now calculate the Z-score:

Z = (difference) / (standard deviation) = 14 / 26 ≈ 0.54.
The average weight beyond which the elevator would be considered overloaded is 180 lbs.

The corresponding Z-score for this weight is approximately 0.54.

Answer:

Take your question 6/7 + 4/8, and find a common denominator. 7 and 8 both go in to 56, so set both denominators to 56.

The question now reads 6/56 + 4/56.

Multiply the numerator by the number of times the denominator was multiplied to get to the common denominator. 8 goes into 56 7 times, and 7 goes into 56 8 times.

Therefor:

7 x 8 = 56, and 8 x 7 = 56.

Now multiply  the numerator by the amount of times the denominator went into the common denominator.

8 x 6 = 48 and 7 x 4 = 28.

what are the positive and negative square roots of 400?​

Answers

The square root of a number is a value that, when multiplied by itself, gives the original number. In this case, the number is 400. So, the positive square root of 400 is a number that, when multiplied by itself, gives 400, and the same goes for the negative square root of 400.

What are the positive and negative square roots of 400?​

The positive square root of 400 is 20, because 20 multiplied by itself equals 400. The negative square root of 400 is -20, because -20 multiplied by itself also equals 400.

It is important to note that in many contexts, the square root of a positive number is taken to be the positive root. However, in some cases, such as solving certain equations or working with geometric objects, both the positive and negative roots may be considered.

In summary, the positive and negative square roots of 400 are 20 and -20, respectively.

It has a 15% annual interest rate.

The interest is compounded monthly.

The card has $0 minimum payments for the first four years it is active.

years for her balance to increase from $300 to $450

Answers

Emma has a credit card with 15% annual interest compounded monthly. The exponential expression is 300(1+0.15/12)^(12*t). She owes $509 in 4 years. It's about $464. Time it will take for her balance to reach $450, which is about 5.6 years. The expression to evaluate her balance with an annual compounding interest rate is 300(1+0.15)^t = 300(1.15)^t. If the card were compounded annually, she would owe about $459 in 4 years and it would take about 6.5 years for her balance to reach $450.

P = $300 (initial balance)

r = 0.15 (annual interest rate)

n = 12 (monthly compounding)

The simplified exponential expression is

300(1+0.15/12)^(12*t)

Using the formula from Part A with t = 4

300(1+0.15/12)^(12*4) ≈ $509

Emma will owe approximately $509 in 4 years if she doesn't make any payments toward the balance.

The equation for the situation is

300(1+0.15/12)^(12*t) = 450

Taking the logarithm of both sides and solving for t:

t = log(450/300) / (12*log(1+0.15/12)) ≈ 5.6 years

It will take about 5.6 years for Emma's balance to reach $450 assuming she doesn't make any payments toward it.

The expression Emma could use to evaluate her balance with an annual compounding interest rate is

300(1+0.15)^t = 300(1.15)^t

After 4 years, Emma would owe approximately $459 for her original purchase of $300.

How to find arc PQ

Knowing that the arc lengths are in degrees and the total for a circle is 360 degrees then we have the equation

8x - 10 + 6x + 10x + 10 = 360

To solve the equation 8x - 10 + 6x + 10x + 10 = 360 for x, we first need to simplify the left side of the equation by combining like terms:

8x + 6x + 10x - 10 + 10 = 24x

Now the equation becomes:

24x = 360

To solve for x, we need to isolate x on one side of the equation by dividing both sides by 24:

24x/24 = 360/24

x = 15

Therefore, the solution for x is 15.

Arc PQ = 8x - 10

The probability of selecting such a permutation is very low, only about 0.31%.

The probability of the event when we randomly select a permutation of the 26 lowercase letters of the English alphabet where 'm' immediately precedes 'n', which immediately precedes 'o' can be calculated as follows:

Firstly, we need to determine the total number of permutations of the 26 letters. Since there are 26 letters in the alphabet, there are 26! ways to arrange them.

Next, we need to determine the number of permutations where 'm' immediately precedes 'n', which immediately precedes 'o'. To do this, we can consider 'mno' as a single unit and then there are 24! ways to arrange the 24 units (23 individual letters and 1 unit of 'mno').

However, there are 3! ways to arrange 'mno' within the unit, so we need to multiply by 3!. Therefore, the total number of permutations where 'm' immediately precedes 'n', which immediately precedes 'o' is 24! x 3!.

Thus, the probability of randomly selecting a permutation where 'm' immediately precedes 'n', which immediately precedes 'o' is:

How many drops does alberto still need to add to the water? Explain how you found your answer

Answers

If after putting in 2/3 of total-drops needed, Alberto stop and answer his phone, then the number of drops that Alberto still need to add to water is 20 drops.

The directions say to use "1 drop" for each 1/4 gallon of water, and Alberto has 15 gallons of water in the tank,

So, the "total-number" of drops needed is :

⇒ Total number of drops needed = (1 drop per 1/4 gallon) × (15 gallons) × (4 quarters per gallon),

⇒ Total number of "drops-needed" is = 60 drops,

Next, we calculate "2/3" of "total-drops" needed,

To find out how many drops Alberto has already added,

We calculate 2/3 of the "total-drops" needed,

⇒ 2/3 of total drops = (2/3) × (total number of drops needed),

⇒ 2/3 of 60 drops = (2/3) × 60 = 40 drops,

So, Alberto has already added 40 drops of water-cleaning drops,

To calculate how many drops Alberto still needs to add, we subtract drops he already added from total drops needed,

⇒ Drops still needed = (Total drops needed) - (Drops already added),

⇒ 60 drops - 40 drops = 20 drops

Therefore, Alberto still needs to add 20 drops.

10^9 cubic meterslake

Step-by-step explanation:

You want to know the number of cubic meters in a cube that is 10^3 meters on each side, and whether that volume amounts to a pond, lake, or ocean.

Volume

The volume of a cube is given by ...

  V = s³

where s is the edge length.

The volume of interest is ...

  V = (10³ m)³ = 10⁹ m³

The volume of oil is 10⁹ cubic meters.

Lake

The sizes of ponds and lakes vary, but we might consider a pond to be a body of water larger than about 150 square meters and less than 6 meters in depth. On the other hand, a lake will generally be larger than about 4000 square meters. An average size lake may be about 10 meters in depth.

If we put the given amount of volume in a space with a depth of 40 meters, it would cover an area of about 25 million square meters, roughly 6000 acres. That is the area of a circle about 7 km in diameter. This might be considered a medium-sized lake.

The oil would fill a medium-sized lake.

A "lake" is generally a body of water upwards of an acre in area. While an average lake in some areas is about 10 m deep, worldwide, the average is just over 40 m in depth. Some lakes are well over 20,000 acres in area.

A "pond" may be larger than a "lake", but will generally be smaller than 500 acres.

m∠D = 35°, DE ≈ 8. 40 units, DF ≈ 13. 65 units

D.

m∠D = 35°, DE ≈ 8. 40 units, DF ≈ 14. 65 units

Answers

The missing angle D is 55 degrees, and the lengths of DE and DF are approximately 8.40 units and 14.65 units, respectively. Therefore, the correct option is (B) m∠D = 55°, DE ≈ 8. 40 units, DF ≈ 14. 65 units

We can start by using the trigonometric ratios of the angles in a right triangle. In particular, we can use the tangent function to find the measure of angle D

tan(D) = DE / FE

tan(D) = DE / 12

We know that angle F is 35 degrees, so angle D must be

D = 90 - F

D = 90 - 35

D = 55 degrees

Now that we know the measure of angle D, we can use the sine and cosine functions to find the lengths of DE and DF, respectively. We know that

sin(F) = DE / DF

cos(F) = FE / DF

Substituting the given values

sin(35) = DE / DF

cos(35) = 12 / DF

Solving for DE and DF

DE = DF × sin(35)

DE = DF × 0.574

DE ≈ 0.574 × DF

DF = 12 / cos(35)

DF ≈ 14.65 units

DE ≈ 0.574 × 14.65

Complete Question:

The rate of consumption of oil in the United States during the 1980s (in billions of barrels per year) is modeled by the function C(t) = 27.08e', where t is the number of years after January 1, 1980. Find the total consumption of oil in the United States from January 1, 1980 to January 1, 1990.

Answers

the total consumption of oil in the United States from January 1, 1980, to January 1, 1990 is approximately 596,533.7 billion barrels.

To find the total consumption of oil in the United States from January 1, 1980 to January 1, 1990, we need to integrate the given function[tex]C(t) = 27.08e^t[/tex]with respect to time t, over the interval [0, 10], where t is measured in years.

The integral of the function is:
∫[tex](27.08e^t) dt[/tex]

To solve this integral, we use the fact that the integral of[tex]e^t[/tex] is [tex]e^t[/tex]itself. Thus, we get:
27.08∫[tex]e^t dt = 27.08e^t[/tex]
Now, we need to evaluate the definite integral over the interval [0, 10]:
[tex]27.08e^t[/tex]| from 0 to 10 =[tex]27.08(e^{10} - e^0)[/tex]

As e^0 = 1, the expression simplifies to:
[tex]27.08(e^{10} - 1)[/tex]
Now, we can calculate the value of the expression:
[tex]27.08(e^{10} - 1) =27.08(22026.47 - 1) = 27.08 * 22025.47 =596533.7[/tex]
Thus, the total consumption of oil in the United States from January 1, 1980, to January 1, 1990 is approximately 596,533.7 billion barrels.

if the pile contains only 25 quarters but at least 50 of each other kind of coin, how many collections of 50 coins can be chosen? collections

Answers

The number of collections of 50 coins that can be chosen from this pile is: C(125, 25) = 177,100,565,136,000
This is a very large number, which shows that there are many possible collections of 50 coins that can be chosen from the pile.

If the pile contains only 25 quarters but at least 50 of each other kind of coin, then the total number of coins in the pile must be at least 50 + 50 + 50 = 150. Let's assume that there are 150 coins in the pile, including the 25 quarters.
To choose a collection of 50 coins from this pile, we need to exclude the 25 quarters and choose 25 coins from the remaining 125 coins. We can do this in C(125, 25) ways, which is the number of combinations of 25 items chosen from a set of 125 items.
Therefore, the number of collections of 50 coins that can be chosen from this pile is:
C(125, 25) = 177,100,565,136,000

There are 351 possible collections of 50 coins that can be chosen, considering the given conditions.

To find the number of collections of 50 coins that can be chosen, we will consider the given conditions:
The pile contains only 25 quarters.

There are at least 50 of each other kind of coin (pennies, nickels, and dimes).
Now, let's break this down step by step:
Determine the minimum number of coins from each kind required to make a collection of 50 coins.
- 25 quarters (as it's the maximum available)
- The remaining 25 coins must be a combination of pennies, nickels, and dimes.
Find the different combinations of pennies, nickels, and dimes that can be chosen to make a collection of 50 coins.
- We need 25 more coins, so we can divide them into three groups:
 a) Pennies (P)
 b) Nickels (N)
 c) Dimes (D)
Calculate the combinations for the remaining 25 coins.
- Using the formula for combinations with repetitions: C(n+r-1, r) = C(n-1, r-1)
 Where n is the number of types of coins (3) and r is the number of remaining coins (25)
- C(3+25-1, 25) = C(27, 25) = 27! / (25! * 2!) = 351.

The ratio of the books in the sample above is representative of the books in a bookcase in the library. If there are 35 yellow books in the bookcase, then how many green books are in the bookcase?

Answers

There are 15 green books in the bookcase.

How many green books are in the bookcase?

The ratio of yellow books to green books in the sample is 7:3. This means that for every 7 yellow books, there are 3 green books.

If there are 35 yellow books in the bookcase, we can use the ratio to find the number of green books:

7 yellow books : 3 green books

35 yellow books : x green books (where x is the number of green books)

To solve for x, we can use cross-multiplication:

7 yellow books * x green books = 35 yellow books * 3 green books

7x = 105

x = 15

Therefore, there are 15 green books in the bookcase.

A circle with center O(2, 3) contains the point A(5, 11).

Answers

The equation of the circle is x² + y² - 4x - 6y - 60 = 0

Equation of a circle :

The equation of a circle is generally given by the formula:

=> (x - a)²+ (y - b)² = r²

Where (a, b) is the center of the circle, and r is its radius. The equation describes all the points (x, y) in the xy-plane that are a fixed distance r from the center point (a, b).

Here we have

A circle with centre O(2, 3) contains the point A(5, 11).  

Since point A(5, 11) is located on the circle with center O(2, 3), use the distance formula to determine whether A is actually on the circle.

The distance between two points (x₁, y₁) and (x₂, y₂) is given by:

=> d = √(x₂ - x₁)² + (y₂ - y₁)²)

Using this formula, the distance between O(2, 3) and A(5, 11) is:

d = √(5 - 2)² + (11 - 3)²)

= √(3² + 8²)

= √(9 + 64)

=√(73)

This distance is the radius of the circle with center O.

Therefore, the equation of the circle is:

(x - 2)² + (y - 3)² = (√(73))²

x² - 4x + 4 + y² - 6y + 9 = 73

x² + y² - 4x - 6y - 60 = 0

Therefore,

The equation of the circle is x² + y² - 4x - 6y - 60 = 0
