Answer:
gf(5) = 289.
fg(x) = 3x^2 + 2.
Step-by-step explanation:
f(5) = 3(5) + 2 = 17
So gf(5) = 17^2 = 289.
fg(x) = 3(x^2) + 2 (we replace the x in f(x) by g(x)).
= 3x^2 + 2.
Grapes is $1.00 a pound and we are trying to find out 3.5 pounds so we multiply the price for one unit by the amount of units. ($1.00 x 3.5 = $3.50)
The answer is
C) $3.50
Answer:
d. $10,234.80
Step-by-step explanation:
we are given
The equipment will cost $26,000
so, Amount is $26000
A=26000
should be invested today at 12%
r=12%=0.12
It is compounded semiannually
so, n=2
t=8
now, we can use formula

now, we can plug values

now, we can solve for P

X= 5 and it also equals -5
