Answer:

Step-by-step explanation:
All you have to do is multiply the original cost of the movie by 100.
aerage rate of change is just the slope from the endpoints of teh interval
ie 
assuming you mean 
evalaute f(5) and f(1)
f(5)=480(0.3)^5=1.1664
f(1)=480(0.3)^1=144
average rate of change=(1.1664-144)/(5-1)=-35.7084
the average rate of change of the function on the interval x=1 to x=5 is -35.7084
Answer:
a = -14
Step-by-step explanation:
a-2/3=-4. Multiply -4 by 3 to get rid of the denominator. This leaves you with a-2 = -12. Move the -2 to the other side to get a = -2-12, which simplifies to a = -14.

Answer:
a. 40 ft²
b. 21 ft²
c. 61 ft²
Step-by-step explanation:
Rectangle area formula: l * w
Triangle area formula: 1/2(bh)
10 * 4
40 ft² for the rectangle
1/2(7 * 6)
1/2(42)
21 ft² for the triangle
40 + 21
61 ft² in total (both the rectangle & the triangle)
