Height of the balls after two bounces is

52/100 × (0.52 ×0.5) = 0.52 × 0.52 × 0.5
= 0.52^2 × 0.5 m

Therefore the series turns into 0.5,0.5(0.52),0.5(0.52)^2,....

So by finding the height f(n) after n bounces would be
f(n) = 0.5(0.52)^n-1

To get the height of the ball of the third path, we need to put n=3

f(3)= 0.5(0.52)^3-1
=0.5(0.52)^2
=0.14m

Answer: B ) 0.5 × (0.52)^n-1 ; 0.14m

A line has a slope of -6 and includes the points (g,-8) and (0,-2). What is the value of g?

Travka [436]

Answer:

Step-by-step explanation:

Equation for line of slope -6 that passes through (0,-2):

y+2 = -6(x-0)

y = -6x - 2

Plug in (g,-8) and solve for g:

-8 = -6g - 2

g = 1

using the distance formula d=√(x2- x1)^2 +(y2-y^1, what is the distance between point (-3,1) and point (-2,4) rounded to the nea

defon

Answer:

$d = \sqrt{(x2 - x1) + (y2 - y1)} \\ d = \sqrt{ (- 3 + 2) + (1 + - 4)} \\ d = \sqrt{ - 1 + - 3 } \\ d = \sqrt{ - 4 } \\ d = - 2$

Y intercept of y=2x-3

3241004551 [841]

Since the equation is in y = mx+b form you can easily determine the y intercept based on the b value present.

Y = mx + b
Y = 2x - 3
B = y intercept = (0,-3).

Help solve for r algebra

bija089 [108]

Answer:

$\frac{20}{7}$

Step-by-step explanation:

Multiply both sides by 7 to get rid of the denominator on the Right Side (RS). Do the same for the left side (LS) by multiplying both sides by 5 to get:

$7r=4(5)$

Simplify: $7r=20$

Divide both sides of the equation by 7 to get: $r=\frac{20}{7}$
