Written as a simplified polynomial in standard form, what is the result when (3x+7)^2 is subtracted from 3?
nadezda [96]

Given:

(3x+7)^2 is subtracted from 3.

To find:

The result of the given statement in the standard form of the polynomial.

Solution:

We need to find the result when (3x+7)^2 is subtracted from 3.

So, the resulted polynomial can be written as:

P(x)=3-(3x+7)^2

On simplification, we get

P(x)=3-((3x)^2+2(3x)(7)+(7)^2)               [\because (a+b)^2=a^2+2ab+b^2]

P(x)=3-(9x^2+42x+49)

P(x)=3-9x^2-42x-49

P(x)=-9x^2-42x-46

Therefore, the resulted polynomial in standard form is -9x^2-42x-46.

Jose works 25 hours a week at $12.50 per hour. How many weeks will he have to work to earn $3,437.50?
Sidana [21]
The answer is 11. You multiply 25 and 12.5 first. then once you find out how much money you get each week, you divide the 3437.5 by the number you got, which is 312.5. Divide 3437.5 by 312.5

To offset college expenses, at the beginning of your freshman year you obtain a nonsubsidized student loan for $15,000. Interest
soldier1979 [14.2K]

Answer:

15000(1.003425)^12t ;

4.11%

4.188%

Step-by-step explanation:

Given that:

Loan amount = principal = $15000

Interest rate, r = 4.11% = 0.0411

n = number of times compounded per period, monthly = 12 (number of months in a year)

Total amount, F owed, after t years in college ;

F(t) = P(1 + r/n)^nt

F(t) = 15000(1 + 0.0411/12)^12t

F(t) = 15000(1.003425)^12t

2.) The annual percentage rate is the interest rate without compounding = 4.11%

3.)

The APY

APY = (1 + APR/n)^n - 1

APY = (1 + 0.0411/12)^12 - 1

APY = (1.003425)^12 - 1

APY = 1.04188 - 1

APY = 0.04188

APY = 0.04188 * 100% = 4.188%
