Answer:
x = -12,
Step-by-step explanation:
-1 + 5/4x = -16
5/4 x = -16 + 1
5/4 x = -15
x = -15 * 4/5
x = -12.
The correct answer is: [C]: " $4290.00 " .

Explanation:

Given: principal, "P": equals: $14,300 ;
rate, "r" : equals: 7.5 % = 7.5 / 100 = 0.075 ;
time, "t" (in years): equals: 4 ;
_________________________________________
What is the interest, "i" ?
_________________________________________
Note: The formula: i = P * r * t .
_________________________________________
So, we plug in our given values for "P", "r", and "t", and solve for "i" (interest).
__________________________
i = ($14,300) *(0.075) * (4) ;
i = $1,490 ; which is answer choice: [C]: " $4290.00 " .

When it hits the ground the height would be 0.
Set h to 0 and solve for t ( time)
0 = -16t^2 + 112t + 144 divide both sides by -16:
T^2 -7t -9
Factor the polynomial :
( t- 8.1) (t+1.1
Solve for t setting each equation to 0:
T = 8.1 or t = -1.1
Time has to be positive, so the answer is
8.1 seconds
Depending on how everything gets rounded it could also be 8 seconds.
