Find the value of x.

A 45, 45, 90 degree right triangle is drawn. One of the 45 degree angles is labeled. The leg adjacent to that 45 degree angle is labeled 5. The leg opposite that 45 degree angle is labeled x. The hypotenuse is labeled y.

Note that the doubling equation can be written as: y = 1000 * 2⁽ˣ/⁷*⁹⁵⁾

The doubling equation for the information given in question 4 can be written as:

y = 1000 * 2⁽ˣ⁺k⁾


To solve for k, we will use the fasts that:

on 240 days after the 100,000- death mark, there will be 2 million deaths.

2000,000 = 100 * x ^(240/k)

Takin the log of both sides we have:

Log 2 (2,000) =log2 (2^240/k))

⇒ Log 2 (2,000) =240/k * log 2(2)

⇒ log 2 (2000) = 240/k
Making k subjet of the formula, we have

k = 240/log2 2000)

k [tex]\approx[/tex] 7.95

Thus, the doubling equation is y = 1000 * 2⁽ˣ/⁷*⁹⁵⁾

Answer:

Median: 31

Mode: 31

Range: 67

Step-by-step explanation:

Median: To find the median, we first need to arrange the numbers in order from smallest to largest:

25, 29, 31, 31, 69, 80, 92

The middle number is 31, so the median is 31.

Mode: The mode is the number that appears most frequently in the set. In this case, the number 31 appears twice, which is more than any other number. So, the mode is 31.

Range: The range is the difference between the largest and smallest numbers in the set. The smallest number is 25 and the largest number is 92, so the range is:

92 - 25 = 67.

Therefore, the median is 31, the mode is 31, and the range is 67.

Answer:

The median of the given set of numbers is 31, the mode is 31, and the range is 67.

Step-by-step explanation:

To find the median, we need to first arrange the numbers in order from smallest to largest:

25, 29, 31, 31, 69, 80, 92

There are seven numbers in the list, which means the middle number will be the fourth number: 31.
Therefore, the median is 31.

To find the mode, we need to determine which number appears most frequently in the list.
In this case, the number 31 appears twice, which is more than any other number in the list.

Therefore, the mode is 31.

To find the range, we need to subtract the smallest number from the largest number. The smallest number is 25 and the largest number is 92, so the range is:

92 - 25 = 67

Therefore, the range is 67.

The account will be worth approximately $13,268.58 in 20 years if it is opened with an initial deposit of $6,500 and earns 3.6% interest compounded semi-annually.

The formula accrued amount in a compounded interest is expressed as;

A = P( 1 + r/n )^( n × t )

Where A is accrued amount, P is principal, r is interest rate and t is time.

Given the data in the question;

Principal P = $6,500

Compounded semi-annually n = 2

Time t = 20 years

Interest rate r = 3.6%

Accrued amount A = ?

First, convert R as a percent to r as a decimal

r = R/100

r = 3.6/100

r = 0.036

Plug in the given values into the above formula.

A = P( 1 + r/n )^( n × t )

A = $6,500( 1 + 0.036/2 )^( 2 × 20 )

A = $6,500( 1 + 0.036/2 )^( 40 )

A = $6,500( 1 + 0.018 )^( 40 )

A = $13,268.58

Therefore, the accrued amount in 20 years is $13,268.58.

y = -x + 7

Slope-intercept form can give us valuable information about a graph.

Point-Slope Form

There are multiple ways to solve this problem; I am simply showing the way I use most often.

We can plug the known information into point-slope form and then simplify the equation into slope-intercept form. Point-slope is written as:

In this equation, y₁ and x₁ are the y and x values we are given and m is the slope. So, plug in the information.

Then, simplify the right side by distributing the -1.

Next, add 4 to both sides.

The equation in slope-intercept form is y = -x + 7.

Slope-intercept Form

Slope-intercept form is written as y = mx + b, where m is the slope and b is the y-intercept. So, our equation, y = -x + 7, shows that the slope is -1 and the y-intercept is 7. Using this information, we can compare the line to other linear functions or graph the line if needed.

Answer:

y = -x + 7 is your correct answer

Step-by-step explanation:

An inequality to represent the domain of the situation: 0 ≤ x ≤ 6

An inequality to represent the range of the situation: 4 ≤ y ≤ 24

If the equation of the function is [tex]c(x) = n(1.35)^x[/tex], the value of n is: 4.

In Mathematics and Geometry, a domain refers to the set of all real numbers for which a particular function is defined.

Furthermore, the vertical extent of any graph of a function represents all range values and they are always read and written from smaller to larger numerical values, and from the bottom of the graph to the top.

By critically observing the graph of this logarithmic function shown in the image attached above, we can reasonably and logically deduce the following domain and range:

Domain = [0, 6] or 0 ≤ x ≤ 6.

Range = [4, 24] or 4 ≤ y ≤ 24.

Next, we would determine the value of n by using the y-intercept (0, 4);

[tex]c(x) = n(1.35)^x\\\\4=n(1.35)^0[/tex]

n = 4.

240° is the coterminal angle of 23×π÷3.

First, we can simplify 23 times π over 3 by noticing that 2π is equivalent to 6 pi over 3, so we can add 2π to 23 times pi over 3 until we get an angle between 0 and 2π (or 0 and 360 degrees).

23 times π over 3 is equivalent to an angle of 360 degrees times (23 times π over 3)/(2π), which simplifies to 360 degrees times 23/2, or 4140 degrees.

To find a coterminal angle between 0 and 360 degrees, we can subtract 360 degrees until we get an angle in that range.

4140 - 360(11) = 240

Therefore, a coterminal angle of 23 times pi over 3 between 0 and 360 degrees is 240 degrees.
