Which of the following sums would be under the radical symbol to find the distance between the points (7, -1) and (-8, -9)?

Alex

So the distance formula is $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ . Using this, our equation is $\sqrt{(7-(-8))^2+(-1-(-9))^2}$ and we can solve for it as such:

$\sqrt{(7-(-8))^2+(-1-(-9))^2}\\ \sqrt{15^2+8^2}$

As we see with this radical, the sum that's under it is 15^2 + 8^2, or the third option.

Give an MN find the value of X and Y

Sever21 [200]

Answer:

x = 21
y = 114

Step-by-step explanation:

Consecutive interior angles are supplementary:

(6x +6)° +(3x -15)° = 180°

9x -9 = 180 . . . . . . . . . . . . . . simplify, divide by °

x -1 = 20 . . . . . . . . . . . . divide by 9

x = 21

Angles of a linear pair are supplementary:

(3x -15)° +(y +18)° = 180°

3(21) -15 + y + 18 = 180 . . . . substitute for x, divide by °

y = 114 . . . . . . . . . . . . . . . . . . subtract 66

5. A standard-size volleyball court has an

Fed [463]

Answer: The width of the court is 30 feet.

Step-by-step explanation:

We know that the area of a rectangle is given by :-

Area = length x width (1)

Given : A standard-size volleyball court has an area of 1,800 square feet.

The length of the court is 60 feet.

To find : The width of the court.

According to (1) , we have

$1800 = 60\times \text{width}$

Then,

$\text{Width}=\dfrac{1800}{60}=30$

Hence, the width of the court is 30 feet.
