The surface area in this equation is 5x4 which is 20
The equation which the civil engineer can use to find the number of rows is 2x² - 12x = 112. Option D
<h3>How to determine the equation</h3>
Let the number of rows be x
Number of cars in each row = x - 6 = 56
Number of rows for parking lot = 2x
Then,
Number of cars for new parking lot = 2x ( x - 6 = 56)
Expand the expression,
2 ( x - 6 = 56)
2x² - 12x = 112
Thus, the equation which the civil engineer can use to find the number of rows is 2x² - 12x = 112. Option D

Answer:
Step-by-step explanation:
we are given equation for position function as
Since, we have to find acceleration
For finding acceleration , we will find second derivative
now, we can find derivative again
Firstly, we will set velocity =0
and then we can solve for t
we get
now, we can plug that into acceleration
and we get
