Answer: 7.2 months
Step-by-step explanation:
Hi, to answer this question we have to substitute f(x) =500 in the equation given:
f(x) = 100(1.25)^x
500= 100(1.25)^x
Solving for x (number of months)
500/100 = 1.25^x
5 = 1.25^x
log 5 =log 1.25^x
log 5 =x (log 1.25)
log 5 /log 1.25 =x
x = 7.2 months

Answer:
x=-2
Step-by-step explanation:
(2/3)^x-1=27/8
Rewriting the right hand side
(2/3)^x-1=(3/2)^3
We know that a^-b = 1/a^b Hint: { 1/(3/2) = 2/3}
(2/3)^x-1=(2/3) ^-3
The bases are the same, so the exponents are the same
x-1 = -3
x -1+1 = -3+1
x = -2
8 x 32 = 256. Both numbers are prime. Hope I helped:)
<span>A=area=22
sq ft; L=length;
W=width=3 2/3 ft
3 2/3 ft=11/3 ft</span>A=L*W<span>A/W=L
22sq ft/(11/3)ft=L
6ft=L
So the length (height) of the poster is 6 feet.</span>
