Answer:
(a)
(b)62.85cm
Step-by-step explanation:
The growth rate of the shrub is given as:
Where t=time in years, h=height in centimeters
(a)First, we solve for the height h(t) by integrating.
(b)The shrub are sold after 7 years of growth. Therefore, we determine the value of h(t) when t=7 years.
The Shrubs are 62.85cm tall when they are sold.
A. simple random
b. systematic
c. cluster
d. stratified
e.convenience
The height is represented by h = -16t² + 4t + 20 and There is only one solution, because the solutions indicate time and time cannot be negative.
<h3>How to solve vertical motion models?</h3>
We are given the vertical model of the diver's jump as;
h = -16t² + vt + s
where;
h is height
t is time
v is velocity
s is distance
A) We are given;
Distance; s = 20 ft
velocity; v = 4 ft/s
Thus;
h = -16t² + 4t + 20
B) The solution of the model is gotten from;
-16t² + 4t + 20 = 0
Solving this quadratic equation gives;
t = 1.25 seconds or -1 second
C) B. There is only one solution, because the solutions indicate time and time cannot be negative.

$820.
If you divide 656 by 8 (since it's 80% of the total price), you get 82.
Multiplying 82 by 10 would equal the original price.
|60| = |-60|
Since modulus function always gives positive output so both numbers will be equal
