Find the distance between the points (7, – 9) and ( – 2, – 4).

Masja [62]

Answer:

7.07106781187

Step-by-step explanation:

Let us use the distance formula:

$d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}$

x2=2

x1=7

y2=4

y1=9

$d = \sqrt{(2 - 7)^{2} + (4-9)^2}$

$d = \sqrt{(-5)^2 + (-5)^2}$

$d = \sqrt{25 + 25}$

$d = \sqrt{50}$

d=7.07106781187 (round to whatever digit neccesary)

Hope this helps!!

Alchen [17]

Answer: 48 sold-out performances must be played in order for you to break even.

Step-by-step explanation:

Let x represent the number of sold-out performances must be played in order for you to break even.

You invest in a new play. The cost includes an overhead of $30,000, plus production costs of $2500 per performance. This means that the total cost of x sold out performances would be

2500x + 30000

A sold-out performance brings you $3125. This means that he total revenue from x sold out performances would be

3125x

To break even, cost = revenue

Therefore,

2500x + 30000 = 3125x

3125x - 2500x = 30000

625x = 30000

x = 30000/625

x = 48

A piece of wire 40 cm long is cut into two piece, each to be bent to make a square.The length of a side of one square is to be 4

SSSSS [86.1K]

Answer: the wire should be cut into 12 cm and 28 cm

Step-by-step explanation:

All sides of a square is equal.

The perimeter of a square is the distance around the square.

Let L represent the length each side of one of the squares. Then the perimeter of this square is 4L.

The length of a side of one square is to be 4 longer than length of a side of the other. This means that the length of each side of the other square is L + 4

The perimeter of the other square would be 4(L + 4) = 4L + 16

Since the piece of wire is 40 cm long, then

4L + 4L + 16 = 40

8L = 40 - 16 = 24

L = 24/8 = 3

The perimeter of the first square is

4L = 4 × 3 = 12

The perimeter of the second square is

4L + 16 = 4 × 3 + 16= 28
