It can actually be done many ways. You must match up the corresponding sides.

For example, 24/20 and x/7 would work so would, 24/x and 20/7, and 7/20 and x/24. Most proportions are set up the same way. You just have to make sure to go in the same order for the two triangles. Sorry if it's confusing.

So let's use-20/7 and 24/x.

First, we multiply 7*24 and 20*x and we get 20x=168

Then we divide to get 168/20. X=8.4

A BASKETBALL PLAYER MAKES A BASKET THROUGH A TEN FOOT HIGH BASKET FROM 20 FEET AWAY. IF THE SHOOTER RELEASES THE BALL FROM 8 FEE

mixas84 [53]

Answer:

The vertical velocity of the ball when released = 10.81 m/s

The vertical velocity of the ball in the basket = 8.81 m/s

Step-by-step explanation:

The given parameters are;

The height of the basket = 10 feet

The horizontal location of the shooter from the basket = 20 feet

The height from which the shooter releases the ball = 8 feet

The horizontal velocity of the ball = 10 ft/s

Therefore, we have;

Time, t = Horizontal distance/(Horizontal velocity)

t = 20/10 = 2 seconds

The vertical velocity is given as follows;

s = u·t - 1/2·g·t²

Where;

u = The vertical velocity

s = The height above the initial height from which the ball is released

s = y - y₀

Where;

y = The final height of the ball in the calculation = The height of the basket = 10 foot

y₀ = The initial height from which the ball is released = 8 feet

∴ s = 10 - 8 = 2 feet

g = The acceleration due to gravity = 9.81 m/s²

Substituting gives;

2 = u × 2 - 1/2 × 9.81× 2²

u = (2 + 1/2 × 9.81× 2²)/2 = 10.81 m/s

The vertical velocity of the ball when released = 10.81 m/s.

The vertical velocity of the ball in the basket is given by the following relation;

v² = u² - 2·g·s

v² = 10.81² - 2×9.81×2 = 77.6161

v = √(77.6161) = 8.81 m/s

The vertical velocity of the ball in the basket = 8.81 m/s

Determine the slope for the line that meets each condition stated. Show your work. Passes through the points ( 3 , 5 ) and ( − 1

Kamila [148]

Answer:

The slope of the line that passes through (-1, -7) and (3, 5) is 3

Explanation:

The slope of the line is calculated using the following rule:

$Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

We are given the following points:

(3 , 5) representing (x₁ , y₁)

(-1 , -7) representing (x₂ , y₂)

To get the slope, we will simply substitute with the givens in the above equation

This is done as follows:

$Slope = \frac{-7-5}{-1-3}=3$

You haven't attached the table for the second part. However, follow the same procedure. Pick two points from the table, substitute with them in the above equation and you'll get the slope

Hope this helps :)
