G(f(x)) is puting f(x) inside g(x) for x
= (-2x+3)² + 5
= (-2x + 3)(-2x+3) + 5
= 4x² - 6x - 6x + 9 + 5
= 4x² - 12x + 14
c.
I’m pretty sure the answer is C
Answer:
18
Step-by-step explanation:
1) if 6 men in 15 days, then 1 man will spent 15*6=90 days to paint the building;
2) if it takes 90 days 1 man, then for 5 men it takes 90/5=18 days.
Given:
Principal = $3000
Rate of interest = 4.7% = 0.047 compounded quarterly.
Time = 12 yeas
To find:
The value of John’s investment after 12 years.
Solution:
The formula for amount is
where, P is principal, r is rate of interest, n is number of times interest compounded in an year, t is number of years.
Substitute P=3000, r=0.047, n=4 and t=12 in the above formula.
Therefore, the required equation is .
We can further solve this.
Therefore, the value of John’s investment after 12 years is $5255.76.
No thats 16/25 which is not 4/5
