Answer:
13 ft
Step-by-step explanation:
We assume your height formula is intended to be ...
h(t) = -16t² +20t +7
This will have its maximum value at ...
t = -b/(2a) = -20/(2(-16)) = 5/8
The height at that time is ...
h(5/8) = (-16(5/8) +20)(5/8) +7 = 10(5/8) +7 = 106/8 = 53/4 = 13 1/4 . . . ft
To the nearest whole foot, the diver will reach a height of 13 ft above the pool.

<em>Additional comments</em>
The standard form quadratic can be described as ...
f(x) = ax² +bx +c
The extreme value occurs at ...
x = -b/(2a)
This can also be written as ...
f(x) = (ax +b)x +c
which can make it easier to evaluate for some numerical value of x.
Answer:
A
Step-by-step explanation:
Calculate the distance d using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = D(- 4, - 3) and (x₂, y₂ ) = E(- 5, 3)
d = 
= 
= 
= 
≈ 6.1 → A

Answer:
The monthly payment for the loan amount for 20 years is $806.167
Step-by-step explanation:
The principal loan amount= $ 50,000
The rate of interest = 7 %
the time period of loan = 20 years = 20 × 12 = 240 months
let the amount after 20 years = $ A
<u>From Compounded method</u>
Amount = Principal × 
or, A = 50,000 × 
or, A = 50,000 × 
Or, A = 50,000 × 3.8696
∴ Amount = $ 193,480
So, The amount after 20 years = $ 193,480
The monthly payment amount = $ 
= $ 806.167
Hence The monthly payment for the loan amount for 20 years is $806.167 Answer
Answer: He made $90 last week.
Assumption :
Let, Luis made $X last week.
He made $72 this week which is 80% of $X that he made last week
⇒ X * 80% = 72
⇒ X * 80/100 = 72
⇒ X = (72 * 100)/80
⇒ X = 90
Therefore, he made $90 last week.
To remember :
While solving this type of problems, be careful to understand which one of last time and current time is not given; just assume that one and input other conditions, the problem will be solved.
