Answer:
72.8
Step-by-step explanation:
c = f + 2
Each time there is a new figure ( f ), two circles ( c ) are added.
f(4) = 12.2
we are given that x = 4, plug in 4 into the equation
f(4) = 5(1+0.25)^(4)
f(4) = 5(1.25)^(4)
raise 1.25 to the 4th, which is equal to 2.44
f(4) = 5(2.44)
In ∆RST and ∆XYZ
RS=YZ(S)
angle RST=angle XYZ(A)
ST=YZ(S)
hence ∆RST ≠~∆XYZ
