N/4.3 = 9.4
4.3 × n/4 = 9.4 × 4.3
n = 40.42
F(-1)
replace all x with -1
f(-1)=-3(-1)^2+2(-1)-7
f(-1)=-3(1)-2-7
f(-1)=-3-9
f(-1)=-12
double every 6 months
in 6 months there would be 250*2 = 500 crickets
in 1 year there would be 500*2 = 1000 crickets
in 1.5 years there would be 1000 *2 = 2000 crickets
in 2 years there would be 2000 *2 = 4000 crickets
The answer is D. 5^-2 times 5^4.
14/4
Multiply the denominator and the whole number - 4*3=12
Add the numerator - 12+2=14
Put the answer over the denominator 14/4
