Answer: 3573.64
Step-by-step explanation:
Exponential Functions:
a=starting value = 19000
r=rate = 11.25%=0.1125
Exponential Decay:
b=1-r=1-0.1125=0.8875
Write Exponential Function:
Plug in time for x:
y=19000(0.8875)^14
y= 3573.6388855
Evaluate :
y=3573.64
Answer: 11.25% depriciation means 11.25% amount decrases per year.
i.e for 1year (1-0.1125)19000=0.8875*19000
so for 14 years multiply 0.08875 14 times to 19000.
Your answer will be arrived.
If any doubt comment.
Answer:
30 or -30
y^2 = 900
Take the square root of each side
sqrt(y^2) = sqrt(900)
y = ±30
