Trava [24]

Answer:

<h3> $2,179.2</h3>

Step-by-step explanation:

Given;

Loan = $36,320 (Principal)

Rate R = 6% = 0.06

Time T = 1year

Required

Interest that will be charged on this loan at the end of the first year

Using the formula for calculating simple interest as;

SI = PRT/100

SI = 36,320 * 6 * 1/100

SI = 0.06 * 36,320

SI = $2,179.2

Hence the amount of interest that will be charged on this loan at the end of the first year is  $2,179.2

nexus9112 [7]

Solution:

Given:

(2x^2+2x+1)(4x-1)

To get the product of the polynomial; we use the distributive property of multiplication.

a(b+c)=ab+ac

\begin{gathered} (4x-1)(2x^2+2x+1) \\ 4x(2x^2+2x+1)-1(2x^2+2x+1) \\ =8x^3+8x^2+4x-2x^2-2x-1 \\ \text{Collecting similar terms together and simplifying further;} \\ =8x^3+8x^2-2x^2+4x-2x-1 \\ =8x^3+6x^2+2x-1 \end{gathered}

Therefore, the product of the polynomials is;

8x^3+6x^2+2x-1
