The square roots of 289 are 17 and -17, so answers DE and OF. Hope this helps:)
Given:
f(x) = 620e^7.8x
The standard equation for an exponential function is f(x) = Aoe^bx
where Ao is the initial amount
b is the growth factor
so, in this case, the initial amount is 620 and the growth factor is 7.8
<span />
2 times 2 times 2 equals 8.
8 plus 1 equals 9
9 plus 4 equals 13.
The answer is 13.
Take 1.3x1.5 and i think that will give you your answer
2. m<-1.5
3. 11≥x
4. x≥1
5. x≥2
