Answer:
30%
Step-by-step explanation:
15.4 m
4
Each walk-in is $5, so 20 divided by 5 is 4. 4 classes.
48.06 to the nearest hundredth.
f(x) = -16x^2 + 2x + 48
To find the maximum height we convert to vertex form:
= -16(x^2 + 1/8x) + 48
= -16[x + 1/16)^2 - 1/256] + 48
= -16(x + 1.16)^2 + 16/256 + 48
= 48.0625.
2(x^2+9)
2x^2 +18
Factor out a 2
