Answer:
y=-2x+1
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals of one another. slope 1/2 perpendicular will be -2/1=-2
y-5=-2(x-(-2))
y-5=-2(x+2)
y-5=-2x-4
y=-2x-4+5
y=-2x+1
(A) The formula for nth bounce is 
.
(B) 4.43 feet is the maximum height of the ball on the 6th bounce.
<h3>What is an algebraic expression?</h3>
An algebraic expression is consists of variables, numbers with various mathematical operations,
Given that,
The height from where the ball is dropped = 20 feet.
Also, the ball bounces and returns to 7/9 to its original height.
(A)
The representation of the maximum height of the ball on the nth bounce can be given as
(B)
The maximum height of the ball on the 6th bounce = 20 (7/9)⁶ = 4.43 feet

Answer:
4 inches
Step-by-step explanation:
In a regular pentagon, all sides are equal in length
Answer:
B
Step-by-step explanation:
We can easily solve this problem by using the Pythagorean Theorem.
The Pythagorean Theorem says:
One Leg ^ 2 + Another Leg ^ 2 = Hypotenuse ^ 2
<u>Note:</u> This theorem holds true for right triangles
This problem is in fact of a right triangle as said. So we use the theorem to find the other leg's length.
One Leg ^ 2 + Another Leg ^ 2 = Hypotenuse ^ 2
8^2 + Another Leg ^ 2 = 17^2
64 + Another Leg ^ 2 = 289
Another Leg ^ 2 = 289 - 64
Another Leg ^ 2 = 225
The other is the square root of 225, which is 15
The correct answer is B
