Start by getting the term with the exponent on one side

take the log of both sides

There is a log rule that says we can bring down the exponent

Solve for x

5x=6.64
answer: x=1.33
Answer:
c
Step-by-step explanation:
17+7 =25
1/5 = 0.20
3/4= 0.75
25 + 0.20 + 0.75
=25 + 0.95
= 25.95
I hope this helped a bit!:)
Price elasticity is defined as

.
Here, the question has omitted to define variables, so we will ASSUME
p=price
x=variable,
and we're given
p+x^2-160=0
We calculate

by implicit differentiation with respect to p:
1+2x (dx/dp)=0
=>
E(x)=(dx/dp)=-1/(2x)
Therefore the price elasticity at x=65 is
E(65)=1/(2*65) =-1/130 (approximately -0.00769)
145 pages because 145 would round up to 150 but anything below 145 would round to 140
