Answer:
Part a) The rule of the sequence is 
Part b) The height of the ball will be 
Step-by-step explanation:
Part a) Write a rule for the sequence using centimeters. The initial height is given by the term n = 1.
we know that
In a <u>Geometric Sequence</u> each term is found by multiplying the previous term by a constant called the common ratio (r)
In this problem we have a geometric sequence
Let
n-----> the number of path
a1 ----> is the initial height
r -----> the common ratio
we have


The rule for the sequence is equal to

substitute

Part b) What height will the ball be at the top of the third path?
For n=3
substitute in the equation


A service call charge or fee is when you are charged a certain amount of money in order for a service technician to perform that specfic service.
let's put value of t in equation.
x = 2√t
x = 2√y
x/2 = √y
(x/2)^2 = y
y = x^2 /4
now let's differentiate it with respect to x.
dy/dx = 2x/4 = x/2
differentiating again wrt to x
d^2y/dx^2 = 1/2
Answer:
B.) -4
Step-by-step explanation:
y=mx+b
b is equal to the y-intercept.
<span><span>Molly: 105 x 05/02 = 42</span>
Kim: 105-42</span> = 63
<span> Laura: 385-105 = 280
280 x 100/385</span><span> = 72%
Donc Laura obtient 72</span>%
