(2x^4 + 3x^2)(x^2-1)
you multiply and you'll get:
2x^8-2x^4+3x^4-3x^2
then add the coefficients with x^4
= 2x^8+1x^4-3x^2

the coefficient for x^4 is 1, so the answer is B

Fynjy0 [20]

Answer:

Step-by-step explanation:

Formula:

d = √(x2−x1)^2 + (y2−y1)^2

plug in

d = √(8−2)^2 + (5−2)^2

d = √(6)^2 + (3)^2

d = √36 + 9

d = √45

Sarah took out a $30,000 loan for 11 years at a 4.7% interest rate to put a new pool in her backyard. If

MissTica

The amount of the loan after 11 years is $34,113.53 and the intereest earned is $4,113.53

<h3>How to calculate the compound interest</h3>

The formula for calculating the exponential function is expressed as:

$A =P(1+\frac{r}{n} )^t$

Given the following

P = 30,000
r = 0.047
t = 11 years
n = 4

Substitute into the formula to have:

$A=30000(1+\frac{0.047}{4} )^{11}\\A =30000(1.13711)\\A =\$34,113.53$

Hence the amount of the loan after 11 years is $34,113.53

<h3>Find the interest earned</h3>

Interest = A - P

Interest = 34,113.53 - 30000

Interest = 4,113.53

Hence the intereest earned is $4,113.53
