The answer is it should be behind the 7 because you only moved one time in 1.7
Answer:
-5=x
Step-by-step explanation:
3=-2 (x+2)
-2 (x+2) = -2x-4
3=-2x-4
-4 from 3 and -4
= -7=-2x
do the opposite "-2 to +2 "
=-5=x
Alexis needs to score at least 96 points on her next test in order to have an average of at least 90.
explanation:
85+89+92+96= 360
359/4=90
So, f[x] = 1/4x^2 - 1/2Ln(x)
<span>thus f'[x] = 1/4*2x - 1/2*(1/x) = x/2 - 1/2x </span>
<span>thus f'[x]^2 = (x^2)/4 - 2*(x/2)*(1/2x) + 1/(4x^2) = (x^2)/4 - 1/2 + 1/(4x^2) </span>
<span>thus f'[x]^2 + 1 = (x^2)/4 + 1/2 + 1/(4x^2) = (x/2 + 1/2x)^2 </span>
<span>thus Sqrt[...] = (x/2 + 1/2x) </span>

Determine the total surface area, T
T is calculated using:
Substitute values for r and h
Remove bracket
Take 
So, we have:
--- approximated.
<em>Hence, the surface area is 1300 square inch</em>
