Answer:
The units of measurement for the composite function c(w(h)) is canvases over weeks.
Step-by-step explanation:
Given :
The function c(t) approximates how many canvases she paints per hour.
The function w(h) represents how many hours per week Christina spends painting the canvases.
To Find: What are the units of measurement for the composite function c(w(h))?
Solution:
C(t)= canvases paints per hour
W(h)=hours per week
C(w(h)) =canvases paints per hour * hours per week
C(w(h)) =canvases per week
So, Option 3 is true
Hence , the units of measurement for the composite function c(w(h)) is canvases over weeks.
h(t) is the height of the diver in feet above the water
Now it asks about the time at which diver reaches the water
When diver reaches the water , the height of diver from water should be zero
So we plug h(t) =0
So
divide whole equation by -16
we can now factor the quadratic equation
So we get
(t+4)(t-3) =0
plug each factor equal to zero and solve for t
t+4 =0 and t-3 =0
So t=-4 and t=3
Now time cannot be negative , So t=3
So time = 3 seconds
It takes 3 seconds for the diver to reach the water
Answer:
4/7
Step-by-step explanation:
Multiply the number by The reciprocal of 1 2/5
4/5*5/7=20/35
Answer:
Step-by-step explanation:
r = 7 cm
h = 15cm
pi = 3.14
Top and bottom (These questions drive you crazy when you don't know if there is both a top and bottom).
Area = 2* pi *r^2 = 2 * 3.14 * 7^2
Area = 2 * 3.14 * 49
Area = 307.72 Don't round this.
Cylinder body
Cylinder body = Circumference * h = 2*pi * r * h
Cylinder body = 2* 3.14 * 7 * 15
Cylinder body = <u> 659.4</u>

Total = 967.12
Rounded 967.1 Answer
