Determine which of the following choices gives the volume of the solid of revolution generated by revolving the region bounded by y=ln(x), y=0, and x=5 around the line y=7. I. π ∫ 1 5 ( 7 − ln ⁡ ( x ) ) 2 d x II. π ∫ 1 5 [ 7 2 − ( 7 − ln ⁡ ( x ) ) 2 ] d x III. 2 π ∫ 1 5 x ( 7 − ln ⁡ ( x ) ) d x IV.

answer: 43/157

this is the answer and if you try to prove me wrong your a meanie

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

answer: hello!

the answer to this problem is, d. (7.3)(8.52)=62.19
