The exponential function f(x) = 84(1.3)* models the change in the number of students playing varsity sports at a school over an eight-year period. What does
the number 1.3 represent?
F
The annual rate of decrease in students playing varsity sports during the
eight years.
G
The number of students playing varsity sports at the beginning of the
eight-year period, expressed in hundreds
The number of students playing varsity sports at the end of the eight-
year period, expressed in hundreds.
H
J
The annual rate of increase in students playing arsity sports during the
eight years.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

i can't see the picture : /

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
