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.
X=50
Can you help me on my recent question?
Answer is 10
Scale factor is 2.5 (30/12)
So you have to do 4 multiplied by 2.5 to get x on the bigger shape.
1: 4 8 12 16 20 and so on.
2: 7 14 21 28 35
3: 9 18 27 36 45
4: 12 24 36 48 60
your basically going and times the number 1, 2, 3, 4, and 5 times.
