Answer:
Step-by-step explanation:
h = −16(x − 2)² + 72
= −16((x − 2)(x − 2)) + 72 expand the square (x - 2)² = (x - 2)(x - x)
= -16 ((x)(x) + (x)(-2) + (-2)(x) + (-2)(-2)) + 72
= -16 (x² + (-2x) + (-2x) + (4) ) + 72
= -16 (x² + (-4x) + (4) ) + 72
= -16 (x² - 4x + 4 ) + 72
= (-16)(x²) + (-16)(-4x) +(-16)(4) + 72
= -16x² + 64x - 64 + 72
= -16x² + 64x + 8 My guess is D ; 72 ???
I have no clue what the ; 72 means after the given answer. It must be a standard form thing I never learned.

Step-by-step explanation:
Answer:
1 in. : 100 mi
Step-by-step explanation:
Scale = 1 inch : 10 miles
In the scale, the quantity is Length
The relationship between length and Area is;
Area = Length * Length
So inch becomes inch^2
1 inch * 1 inch = 1 i
10 miles * 10 miles = 100
The correct option is;
1 in. : 100 mi
Answer:
41
Step-by-step explanation:
3x+4y÷2 for x= 7 and y=10
Substitute the variables with the numbers.
3(7) + 4(10) ÷ 2
3 x 7 = 21
4 x 10 = 40
21 + 40 ÷ 2
Use PEMDAS to complete
40 ÷ 2 = 20
20 + 21 = 41
Answer is 41

Answer:
f(x)=-75
Step-by-step explanation:
since f(x) varies directly with x
it implies that f(x)=Kx
k=f(x)/x
when f(x)=50 and x=-10
k=50/-10
k=-5
but when x=15, f(x)=-5×15
f(x)=-75
