HELP PLEASE?

Answer 1

Sorry my browser crashed.

This only gives you the first and last term so in order to find the common ratio r:
134456/8 = 16807
16807^1/5 = 7
8(1-(7)^6) / (1-7)
= 8(1-7^6)/6
= 156864
= C

Answer 2

(x+8)(x-4)
x^2 + 8x - 4x - 32
x^2 - 4x - 32
D

Answer 3

Remember the binomial multiplication method FOIL (first outer inner last)

Answer 4

Substitute g(x) into f(x)
(3x+6)-4
3x+2 = D

Answer 5

I remembered polynomial graphing with an acronym: POLH (along with PEHH, NOHL, NELL)
Positive (Coefficient) Odd (Exponent) -- starts low, ends high (A)

Answer 6

2 parts to this one.

Answer 7

A. The local maximum is definitely to the left of the y-axis because only one of the coefficients is negative, and it's -2x.

Answer 8

factor out a 5x from the numerator
5x(2x^2-x+3) / 5x
= 2x^2 - x +3
= B

Answer 9

Synthetic division yields 3x^2+15x+18
Multiply by 1/3 (since 3x-1 = 0; x = 1/3)
x^2+5x+6
A

Answer 10

A. the full answer is 2x^2 +3x^2 +3x + 3 + 8/x-2.

Answer 11

2x^3*
