Answer:
1. f(x) = -2x^2-12x-19
2. f(x)= 2x^2+12x+17
3. f(x)= -2x^2+12x-17
4. f(x)= 2x^2-12x+17
Step-by-step explanation:
Just took the same test. :)
The formula is Interest = principle times rate times time in years.
I=prt
p=1000
r= 0.025
t=x
To find the amount of interest that is earned in a specific time frame, subtract the final amount of money by the principal. 1500-1000=500.
500 = 1000(0.025)x
500 = 25x
x= 20 years
\left(\mathrm{Decimal:\quad }x=-0.75\right)
hope it helps :P
The answer would be A. He should use the mean because it is in the center of the data. I hope this helped ^^
