LenKa [72]

Answer:

y = 1/4x - 8

Step-by-step explanation:

So we do not have the capabilities of graphing but I will help you find the equation.

Slope intercept form: y = mx + b

b = y intercept

A ball is dropped from a height of 500 m the table shows the height of each bounce write a rule to represent the height of the b
JulsSmile [24]

The rule that represents the height of the ball after each bounce is;

H(n) = 400(0.8)^(n - 1)

<h3>Geometric Sequence Progression</h3>

From online sources, we have that;

After first bounce, height = 400 m

After 2nd bounce, height = 320 m

After 3rd bounce, height = 256 m

Formula for the nth term of a geometric sequence is;

T_n = ar^(n - 1)

First term is 400m

Since second term is 320, then common ratio is;

r = 320/400

r = 0.8

Thus, the 6th bounce which is the 6th term will be;

T_6 = 400 * 0.8^(6 - 1)

T_6 = 131 m
