Answer:
A pie graph would be a good graph to use
We have the height h(t) as
h(t) = -16t² + 1024
16t² is how far we've fallen as a function of time; since we started 1024 feet up the height is 1024-16t².
Answer: the distance the brush falls in t seconds, first choice
Answer:
m less-than-or-equal-to 28
Step-by-step explanation:
Xander's charge for m miles will be (3 +1.50m). He wants this to be no more than $45, so ...
3 +1.50m ≤ 45
1.50m ≤ 42 . . . . . . subtract 3
m ≤ 28 . . . . . . . . . .divide by 1.5
27.7-14=Cost above 500 msg
13.7=C
E=number of Extra messages sent
C=0.1E
13.7/0.1=E
137=E
Total messages=T
T=500+E
T=500+137
T=637
