Answer:

Step-by-step explanation:

Given

x² = 36 ( take the square root of both sides )

$\sqrt{x^2}$ = ± $\sqrt{36}$

x = ± 6

that is x = - 6, 6 → C

Answer: x=6

Step-by-step explanation: To solve for x you do the opposite operation to both sides so since x is squared you'd find the square root of x^2 which would be x and the square root of 36 which is 6.

The following formula is used to calculate the monthly payment on a personal loan. P = P V times StartFraction i over 1 minus (1

blondinia [14]

The number of periods over which interest is calculated on the loan.

We have to determine

The following formula is used to calculate the monthly payment on a personal loan.

<h3>What is the formula used to calculate monthly payments?</h3>

The formula used to calculate monthly payments are as follows;

$\rm P = PV \times \dfrac{i}{1-(i+1)^{-n}}$

Where,

1. PV is the present value or the amount of the loan.

2. i is the interest rate per period and is calculated by dividing the yearly percent rate by 100 and by the number of periods in a year.

3. n is the total number of periods and is calculated as the product of the number of periods in a year times the number of years.

Hence, the number of periods over which interest is calculated on the loan.

3k^2=11+6k : complete the square

WARRIOR [948]

Answer:

3(k - 1)² = 12

Step-by-step explanation:

To complete the square, write the equation standard form and make the a term's coefficient 1.

3k² = 11 + 6k

3k² - 6k - 11 = 0

3(k² - 2k) = 11

Take the middle term -2k and divide the coefficient in 2 and square it. Here it is -2/2 = -1. -1² = 1. Add 1 to both sides.

3(k² - 2k + 1) = 11 + 1

3(k - 1)² = 12

A circle with radius of 1 cm sits inside a 3 cm x 4 cm rectangle.

White raven [17]

The area of shaded-region is 8.86 cm^2

Step-by-step explanation:

We can see that there is a circle and a triangle in the given figure

In order too find the area of shaded region, we have to find the area of rectangle and circle first. The area of the shaded region will be obtained by subtracting the area of circle from the area of rectangle.

So,

<u>Area of circle:</u>

Radius = r = 1 cm

So,

$A_c = \pi r^2\\= 3.14 * (1)^2\\= 3.14*1\\= 3.14\ cm^2$

<u>Area of rectangle:</u>

Length of rectangle = l = 4 cm

Width of rectangle = w = 3 cm

So,

$A_r = l*w\\= 4 *3\\=12 cm^2$

Now,

$Area\ of\ shaded-region = A_r - A_c\\= 12 - 3.14\\=8.86\ cm^2$

The area of shaded-region is 8.86 cm^2
