Joseph has a credit card with his bank but he must pay off completely each month for each day that His payment is late the bank
CaHeK987 [17]

Answer:

3%

Step-by-step explanation:

First find the difference between the total payment and what the payment would have been prior to to the 20 days late fee. Divide that number by the amount of days overdue (20) to find the cost of each day overdue. Divide that number of what each day overdue is by the cost of the bill prior to overdue fees. Move the decimal two places to the right.

Use completing the square to determine which of the following gives the solutions to 3x2 - 24x + 40 = 28.
jeka94

Answer:

x=4+2\sqrt{3}

x=4-2\sqrt{3}

Step-by-step explanation:

<u>Completing the square</u>

when  ax^2+bx+c=0

Given equation:

3x^2-24x+40=28

Subtract 40 from both sides:

\implies 3x^2-24x=-12

Divide both sides by 3:

\implies x^2-8x=-4

Add the square of half the coefficient of x to both sides:

(\frac{b}{2})^2=(\frac{-8}{2})^2=16

\implies x^2-8x+16=-4+16

Factor the left side and simplify the right side:

\implies (x-4)^2=12

Square root both sides:

\implies x-4=\pm\sqrt{12}

Add 4 to both sides and simplify the radical:

\implies x=4\pm\sqrt{4 \cdot 3}

\implies x=4\pm\sqrt{4}\sqrt{3}

\implies x=4\pm2\sqrt{3}
