40 = 5 (w - 2)            would be the equation.

40 = 5w - 10              using the distributive property.

+ 10        + 10             because you must add to both sides to get rid of the 10.

50 = 5w

/5      /5                      again, keep the same on both sides, and...

10 = w

The height of the hill is approximately 25.73 ft. Where v0 is the initial velocity (108 ft/s), g is the acceleration due to gravity \((-32.2 ft/s^2)\),

To find the height of the hill, we can use the formula for the vertical position of an object under constant acceleration:

h = h0 + v0t + 1/2at^2

where h is the final height, h0 is the initial height, v0 is the initial velocity, t is the time, and a is the acceleration due to gravity (-32.2 ft/s^2).

In this case, we are given that the initial height h0 is 3 ft, the initial velocity v0 is 108 ft/s, and the time t is 9.5 s. We want to find the height of the hill, which we can denote as h_hill. The final height is the height of the plain, which we can denote as h_plain and assume is zero.

At the highest point of its trajectory, the arrow will have zero vertical velocity, since it will have stopped rising and just started to fall. So we can set the velocity to zero and solve for the time it takes for that to occur. Using the formula for velocity under constant acceleration:

v = v0 + at

we can solve for t when v = 0, h0 = 3 ft, v0 = 108 ft/s, and a = -32.2 ft/s^2:

0 = 108 - 32.2t

t = 108/32.2 ≈ 3.35 s

Thus, it takes the arrow approximately 3.35 s to reach the top of its trajectory.

Using the formula for the height of an object at a given time, we can find the height of the hill by subtracting the height of the arrow at the top of its trajectory from the initial height:

h_hill = h0 + v0t + 1/2at^2 - h_top

where h_top is the height of the arrow at the top of its trajectory. We can find h_top using the formula for the height of an object at the maximum height of its trajectory:

h_top = h0 + v0^2/2a

Plugging in the given values, we get:

h_top = 3 + (108^2)/(2*(-32.2)) ≈ 196.78 ft

Plugging this into the first equation, we get:

h_hill = 3 + 108(3.35) + 1/2(-32.2)(3.35)^2 - 196.78

h_hill ≈ 25.73 ft

If the arrow is launched at t0, the equation describing velocity as a function of time would be:

v(t) = v0 - gt

Answer: 0.8

Step-by-step explanation:

The formula to find area of a parallelogram is A = bh. This means that area = base x height. You can manipulate this formula to what height equals instead of the area. To do that, you can divide b on both sides. This would make the equation h = A/b.

Now that you know how to find what height equals, first find the base of the parallelogram. To find b, multiply 6 x 5. 6 x 5 = 30. This means that your base is 30.

Take the information given to you in the problem about the area. The area is given to you. We know that the area is 24 squared units. Remember what the equation to find height is. It's h = A/b. Substitute the variables for your numbers. h = 24/30.

24/30 = 0.8.

This means that your height is 0.8. This would be 8/10 in fraction form, but you can simplify it further to 4/5.

Hope it helps. Good luck!

Answer:

A(x) = 2x² - 20x + 110

Step-by-step explanation:

A(x) = 2(x - 5)² - 60

A(x) = 2(x - 5)(x - 5) - 60

A(x) = 2[x(x - 5) - 5(x - 5)] - 60

A(x) = 2[x(x) - x(5) - 5(x) + 5(5)] - 60

A(x) = 2(x² - 5x - 5x + 25) - 60

A(x) = 2(x² - 10x + 25) - 60

A(x) = 2(x²) - 2(10x) + 2(25) - 60

A(x) = 2x² - 20x + 50 + 60

A(x) = 2x² - 20x + 110

Answer:

A(x) = 2x² - 20x - 10

Step-by-step explanation:

A(x) = 2(x - 5)² - 60 ← expand factor using FOIL

      = 2(x² - 10x + 25) - 60 ← distribute parenthesis

     = 2x² - 20x + 50 - 60 ← collect like terms

To calculate Karl Pearson's coefficient of skewness, we need to use the formula:

Skewness = 3 * (Mean - Mode) / Standard Deviation

Given the Mean = 73.19, Mode = 79.56, and Variance = 16, we need to find the Standard Deviation first.

Standard Deviation = √Variance = √16 = 4

Now we can substitute the values into the formula:

Skewness = 3 * (73.19 - 79.56) / 4

Skewness = -6.37 / 4

Skewness = -1.5925

Rounded to four decimal places, the Karl Pearson's coefficient of skewness for the given values is approximately -1.5925.

The requried, Gage stocks Pond A with 15 bass and 45 bluegills.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
Let x be the number of basses in Pond A.

Then the number of bluegills in Pond A is 60 - x.

According to the problem, Pond B has twice the number of bass as Pond A, so there are 2x bass in Pond B.

Similarly, Pond B has six times the number of bluegills as Pond A, so there are 6(60 - x) bluegills in Pond B.

The total number of fish in Pond B is 300, so we can set up an equation:

2x + 6(60 - x) = 300

Simplifying and solving for x, we get:

2x + 360 - 6x = 300

-4x = -60

x = 15

Therefore, Gage stocks Pond A with 15 basses and 45 bluegills.

The area of the shaded region is equal to 12.5π or 39.27 square centimeters.

In Mathematics and Geometry, the area of a semicircle can be calculated by using this formula:

Area of semicircle, As = πr²/2

Where:

r represents the radius of a circle.

Note: Radius = diameter/2 = 20/2 = 10 centimeters.

By substituting the radius into the formula for the area of a semicircle, we have the following;

Area of semicircle = 1/2 × π × 10²

Area of semicircle = 50π square centimeters.

For the circle, we have:

Area of circle, Ac = πr²

Area of circle, Ac = π(10/2)²

Area of circle, Ac = 25π square centimeters.

Now, we can determine the area of the shaded region as follows;

Area of shaded region = (As - Ac)/2

Area of shaded region = (50π - 25π)/2

Area of shaded region = 12.5π or 39.27 square centimeters.
