F(x)=125-(125*0.2x)
to find the value of the phone after 3 years, you put x=3.
f(3)=125-(125*0.2(3))
f(3)=50
To write an equation of a line, you need to also know the slope or have a graph
34/4=8.5
8.5x5=42.5
The answer is $42.50
Answer:
469.42 ft²
Step-by-step explanation:
w/sin27 = 38/sin40
w = sin27*38/sin40
w = 26.84 ft
∡X = 180 - 27- 40 = 113º
A = 0.5*(26.84)*(38)*sin(113)
A = 469.42 ft²
