The table shows the volume of water in cubic meters, V, in a tank after water has been pumped out after water has been pumpee out for a certain number of minutes. Which ewuation could represent the volume of water in cubif meters after T minutes of water being pumped out

Answers

Answer 1

The equation that represents the volume of water in cubic meters after T minutes of water being pumped out is V = -1.5T + 30.

The given data shows that the volume of water is decreasing as time goes on. Therefore, we need to use a function that is decreasing with respect to time. One such function is a linear function.

Let V be the volume of water in cubic meters after T minutes of water being pumped out. Then, we can use the two points (0, 30) and (15, 7.5) to find the equation of the line that represents the volume of water in terms of time.

The slope of the line is

slope = (change in volume) / (change in time) = (7.5 - 30) / (15 - 0) = -1.5 cubic meters per minute

The y-intercept of the line is the volume of water when time is zero, which is 30 cubic meters.

Therefore, the equation that represents the volume of water in cubic meters after T minutes of water being pumped out is

V = -1.5T + 30

Applying the right triangle altitude theorem and the leg rule, we have:

5. x = 6; y ≈ 6.7; z ≈ 13.4       6. x = 32; y ≈ 35.8; z ≈ 17.9

What is the Right Triangle Altitude of a Theorem?

The right triangle altitude theorem states that the altitude drawn on the hypotenuse of a right triangle is equal to the geometric mean of the two line segments into which the altitude divides the hypotenuse.

5. To find x, apply the right triangle altitude theorem, which is:

x = √(3*12)

x = √36

x = 6

Using the leg rule, we can find y and z. It is expressed as:

hypotenuse/leg = leg/part

Therefore, substitute and find y:

(3 + 12) / y = y / 3

Cross multiply:

y² = 15 * 3

y = √45

y ≈ 6.7

Find z using the leg rule:

15/z = z/12

z² = 180

z = √180

z ≈ 13.4

6. Use the same theorem and leg rule as done in question 5:

Find x:

16 = √(8 * x)

16² = 8x

256 = 8x

x = 256/8

x = 32

Find y using the leg rule:

(8 + 32) / y = y/32

y² = 40 * 32

y = √1,280

y ≈ 35.8

Find z:

40/z = z/8

z² = 40 * 8

z = √320

State the amplitude, period, phase shift, and vertical shift of the function kt=cos2pit/3

Answers

Answer:

The given function is k(t) = cos(2πt/3).

The general form of a cosine function is A*cos(Bx - C) + D, where:

A is the amplitudeB is the frequency (which is related to the period)C is the phase shiftD is the vertical shift

Comparing this form to the given function, we can see that:

The amplitude of k(t) is A = 1, since the maximum value of the cosine function is 1 and the minimum value is -1.The frequency of k(t) is B = 2π/3, since the argument of the cosine function is 2πt/3. The frequency is related to the period T by the formula T = 2π/B. Therefore, the period of k(t) is T = 3.The phase shift of k(t) is C = 0, since there is no horizontal shift in the argument of the cosine function.The vertical shift of k(t) is D = 0, since the average value of the cosine function over one period is zero.

Therefore, the amplitude of k(t) is 1, the period of k(t) is 3, the phase shift of k(t) is 0, and the vertical shift of k(t) is 0.

An angle measures 37.6° more than the measure of its complementary angle. What is the measure of each angle?

Answers

The pair of required complementary angles are 26.2° and 63.8° respectively.

What are complementary angles?

Two angles are said to be supplementary angles because they combine to generate a linear angle when their sum is 180 degrees.

When two angles add up to 90 degrees, however, they are said to be complimentary angles and together they make a right angle.

If the total of two angles is 90o (ninety degrees), then the angles are complementary.

A 30-angle and a 60-angle, for instance, are two complementary angles.

So, to find the 2 angles which are complementary:

x + x + 37.6 = 90

Now, solve it as follows:

x + x + 37.6 = 90

2x = 90 - 37.6

2x = 52.4

x = 52.4/2

x = 26.2

Now, x = 26.2 and the second angle x + 37.6 is = 26.2 + 37.6 = 63.8°.

Therefore, the pair of required complementary angles are 26.2° and 63.8° respectively.

what is the probability that abby, barry, and sylvia win the first, second, and third prizes, respectively, in a drawing if 200 people enter a contest and winning more than one prize is allowed?

Answers

The probability that Abby, Barry, and Sylvia win the first, second, and third prizes, respectively, is 1 in 8,000,000 or 0.0000125%

How to calculate the probability?

Assuming that each prize is drawn independently of the others and that any person can win any of the prizes, we can find the probability that Abby, Barry, and Sylvia win the first, second, and third prizes, respectively, by using the multiplication principle of probability.

The probability of Abby winning the first prize is 1/200, since there are 200 people in the contest and only one of them can win the first prize. Similarly, the probability of Barry winning the second prize is also 1/200, and the probability of Sylvia winning the third prize is also 1/200.

Since winning more than one prize is allowed, the probability of all three of these events occurring simultaneously is simply the product of their individual probabilities:

P(Abby wins 1st prize AND Barry wins 2nd prize AND Sylvia wins 3rd prize) = (1/200) * (1/200) * (1/200) = 1/8,000,000

Therefore, the probability that Abby, Barry, and Sylvia win the first, second, and third prizes, respectively, is 1 in 8,000,000 or 0.0000125%

What is the value of x?

Answers

Answer:

X= 22

Step-by-step explanation:

So all the angles in a triangle will have a sum of 180°

since you already have a 90° angle you can make the equation

2x+3x-20=90

you'll add the 2x and 3x to get 5x and then you'll also add 20 on both sides

20+90=110

the equation you'll then have is 5x=110

now you'll divide five from both sides and 110/5 is 22

Carlos is older than Adriel. Their ages are consecutive odd integers. Find Carlos's age if the product of their ages is 15.

Answers

Carlos is 5 years old.

Define quadratic formula

The quadratic formula is a mathematical formula used to find the solutions (or roots) of a quadratic equation of the form ax² + bx + c = 0, where a, b, and c are coefficients and x is the variable. The formula is:

x = (-b ± √(b²- 4ac)) / 2a

Let's assume that Adriel's age is x. Then, Carlos's age would be x+2 (since they are consecutive odd integers and Carlos is older).

According to the problem, the product of their ages is 15. So we can set up the equation:

x(x+2) = 15

Expanding the left side of the equation, we get:

x² + 2x = 15

Subtracting 15 from both sides, we get:

x² + 2x - 15 = 0

Now we can solve for x using the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

In this case, a = 1, b = 2, and c = -15. Substituting these values, we get:

x = (-2 ± √(2²- 4(1)(-15))) / 2(1)

x = (-2 ± √64) / 2

x = (-2 ± 8) / 2

x = -5 or x = 3

Since Adriel's age cannot be negative, we can discard the first solution. Therefore, Adriel's age is 3, and Carlos's age is x+2 = 5. So Carlos is 5 years old.

for the function over the interval
10 A.) 150 calories per cm of diameter
B.) 33 calories per cm of diameter
C.) 65calories per cm of diameter
D.) 215 calories per cm of diameter

Answers

Answer:

To find the average rate of change of the function f(x) = 1.5x² over the interval [10, 11], we need to calculate the change in f(x) over the interval, and divide by the change in x.

The change in f(x) over the interval [10, 11] is:

f(11) - f(10) = (1.511^2) - (1.510^2) = 165 - 150 = 15

The change in x over the interval [10, 11] is:

11 - 10 = 1

Therefore, the average rate of change of the function over the interval [10, 11] is:

(15/1) = 15

This means that for every 1 cm increase in diameter (i.e., for every 1 unit increase in x), the number of calories in the pancake increases by an average of 15 calories per cm of diameter.

Therefore, the answer is (A) 150 calories per cm of diameter.

Thabo opens an investment account and invest an amount of money at 8. 00% interest per year, compounded monthly. After a number of years, he has accumulated an amount of R 7 365. 00 in the account. The investment earned R2 000. 00 interest in this period. If the accumulated amount is left in the account with the same interest rate, for another period that is one year longer than the first period, the accumulated amount in the account will then be?

Answers

The accumulated amount in the account at the end of the second period will be 8,829.71.

We can use the formula for compound interest to solve this problem. The formula is,

A = P(1 + r/n)^(nt)

where A is the accumulated amount, P is the principal (initial amount invested), r is the interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the time (in years) for which the money is invested.

Let's use this formula to find the initial principal, P

7,365 = P(1 + 0.08/12)^(12*number of years)

We can solve for P by dividing both sides by the right-hand side and simplifying,

P = 7,365 / (1 + 0.08/12)^(12*number of years)

Now we know that the initial principal was P, and it earned R2 000.00 in interest during the first period. Therefore, the accumulated amount at the end of the first period was,

A1 = P + R2 000.00

A1 = P + P(0.08/12)

A1 = P(1 + 0.08/12)

Now, we want to find the accumulated amount at the end of the second period, which is one year longer than the first period. We can use the same formula as before, but with a time of (number of years + 1),

A2 = P(1 + 0.08/12)^(12*(number of years + 1))

We know that A1 = P(1 + 0.08/12), so we can substitute this into the formula for A2,

A2 = A1(1 + 0.08/12)^(12)

A2 = (P(1 + 0.08/12))(1 + 0.08/12)^(12)

A2 = P(1 + 0.08/12)^13

Now we can substitute the expression we found for P earlier,

A2 = (7,365 / (1 + 0.08/12)^(12*number of years))(1 + 0.08/12)^13

A2 = 7,365(1 + 0.08/12)^(12*number of years + 13)

A2 = 7,365(1.007)^((12*number of years) + 13)

Answers

The dimensions will minimize the cost of fence 3555C, armer needs a fenced-in 1 square kilometer rectangular region.

Let the length of the rectangular region be 'l' and the width be 'w'. The area of the rectangular region is given by:

A = lw = 1 sq. km = 1000 x 1000 sq. m

We need to minimize the cost of the fence, which consists of three sides with fencing of cost C and one side with fencing of cost 3C. The total cost of the fence is given by:

Cost = 3Cw + C(2l + w) = 2C(l + w) + Cw

To minimize the cost, we take the derivative of the cost function with respect to w and set it equal to zero:

dCost/dw = 2C - C[tex]w^{(-2)}[/tex]l = 0

Solving for l, we get:

l = 2w

Substituting this value of l in the area equation, we get:

w(2w) = 1000000

2w² = 1000000

w² = 500000

w = √(500000) m = 707.1 m

So, the width of the rectangular region is 707.1 m and the length is 2w = 2 x 707.1 m = 1414.2 m.

Therefore, the dimensions that minimize the cost of the fence are 707.1 m x 1414.2 m and the minimum cost of the fence is:

Cost = 2C(l + w) + Cw = 2C(1414.2 + 707.1) + C(707.1) = 3555C.

Answers

Answer:

Starting with the given equation:

Ob₁ = 2h/A - 2b₂

We want to solve for b₁. First, we can simplify the equation by multiplying both sides by 2:

2Ob₁ = 4h/A - 4b₂

Next, we can add 4b₂ to both sides to isolate the term involving b₁:

2Ob₁ + 4b₂ = 4h/A

Then, we can multiply both sides by A/4h to solve for b₁:

b₁ = (2Ob₁ + 4b₂) * A/4h

Simplifying this expression, we get:

b₁ = (O/h + 2b₂) * A/2

Therefore, the solution for b₁ is:

b₁ = (O/h + 2b₂) * A/2

or

b₁ = (A O + 2b₂h)/2h

Final answer:

In the equation A=bh, b can be solved as b=A/h. For the equation h(b₁ + b₂)=2, b₁ can be solved as b₁=2/h-b₂

Explanation:

To solve the equation A = bh for b, we can isolate b by dividing both sides of the equation by h. Thus, b = A/h. For the equation h(b₁ + b₂) = 2, we isolate b₁ by first dividing both sides by h to get (b₁ + b₂) = 2/h. Then, we can subtract b₂ from both sides to solve for b₁, yielding b₁ = 2/h - b₂.

Write a sine function that has an amplitude of 3, a midline of y =2 and a period of 1

Answers

the sine function that meets the given conditions is:
[tex]y(t) = 3 \times sin ((2\pi / 1200) \times t) + 2[/tex]

Function with the given characteristics.

The terms and their definitions we need to consider:
Amplitude:

The maximum displacement from the midline (in this case, 3)
Midline:

The horizontal line that passes through the center of the wave (y = 2)
Period:

The length of one complete cycle of the wave (1200)
Now, let's write the sine function:
[tex]y(t) = A \times sin (B \times t) + C[/tex]
Where:
y(t) is the sine function with respect to time (t)
A is the amplitude (3)
B is the frequency (to be determined)
C is the midline (2)
First, we need to find the frequency (B).

The period and frequency are related by the following formula:
[tex]Period = 2\pi / B[/tex]
In this case, the period is 1200:
[tex]1200 = 2\pi / B[/tex]
Now, solve for B:
[tex]B = 2\pi / 1200[/tex]
Now, we can plug in the amplitude (A), frequency (B), and midline (C) into our sine function:
[tex]y(t) = 3 \times sin((2\pi / 1200) \times t) + 2[/tex]

consider straight wires of equal lengths with their ends soldered together to form the edges of a cube. either silver or copper wire can be used for each edge. how many different ways can the cube be constructed?

Answers

The number of valid ways to construct the cube is [tex]4096 - 48 = 4048[/tex]

Each corner of the cube is formed by three wires coming together. Since the wires are soldered together at the ends, each corner must have either 3 silver wires or 3 copper wires coming together.

There are two choices for each wire: it can be silver or copper. Since there are 12 edges in a cube, there are 2 choices for each edge, giving a total of [tex]2^12 = 4096[/tex] possible arrangements of the edges.

However, not all of these arrangements are valid. We must eliminate the arrangements where at least one corner has two silver wires and one copper wire

There are 8 corners in a cube, and for each corner, there are 3 ways to choose which wire is different from the other two. Once we choose which wire is different, there are 2 choices for its color (silver or copper). Thus, there are [tex]8 x 3 x 2 = 48[/tex] invalid arrangements.

You are helping with some repairs at home. You drop a hammer and it hits the floor at a speed of 4 feet per second. If the acceleration due to gravity (g) is 32 feet/second 2, how far above the ground (h) was the hammer when you dropped it? Use the formula:

Answers

Step-by-step explanation:

vf = vo + at      vo = 0 in this case  ( you dropped it from 'at rest')

4 f/s = 32 t

t = 1/8 s

df = do + vot + 1/2 at^2                  df = final position = 0 ft (on the ground)

0 = do  + 0   + 1/2 (-32)(1/8)^2

   solve for do = 1/4 foot

an appropriations bill passes the u.s. house of representatives with 47 more members voting in favor than against. if all 435 members of the house voted either for or against the bill, how many voted in favor and how many voted against? in favor members against mem

Answers

194 member voted against the bill whereas 241 members voted in favour of the bill.

What is bill refers to?

A bill usually refers to a piece of paper money, such as a dollar bill or a euro bill.

To solve this problem, we can use algebra. Let's call the number of members who voted against the bill "x". Then, the number of members who voted in favor of the bill would be "x + 47" (since there were 47 more members voting in favor than against).

We know that the total number of members who voted (either for or against) was 435. So, we can write an equation:

x + (x + 47) = 435

Simplifying this equation, we get:

2x + 47 = 435

Subtracting 47 from both sides:

2x = 388

Dividing both sides by 2:

x = 194

So, 194 members voted against the bill, and the number of members who voted in favor would be:

x + 47 = 194 + 47 = 241

Therefore, 241 members voted in favor of the bill.
