Find the distance between the given points: (2, -2) and (-4, 7)

sasho [114]

Answer:

$3\sqrt{13}$

Step-by-step explanation:

Hi there!

We want to find the distance between the points (2, -2) and (-4, 7).

To do that, we can use the distance formula.

The distance formula is given as $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ , where $(x_1, y_1)$ and $(x_2, y_2)$ are points

We have everything needed to find the distance, but let's label the values of the points to avoid any confusion

$x_1=2\\y_1=-2\\x_2=-4\\y_2=7$

Now substitute those values into the formula and solve

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

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

Simplify

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

$\sqrt{(-6)^2+(9)^2}$

Square the numbers under the radical

$\sqrt{36+81}$

Add the numbers under the radical together

$\sqrt{117}$

Simplify the square root

$3\sqrt{13}$

Hope this helps!

A small town had a population of 960 people last year. The population increased to 1200 people this year. By what percentage did

Licemer1 [7]

Answer:

25% of 960 is 240. to find that we need to do...

0.25 x 960 = 240

add the percent increace to the 960.....

960 + 240 = 1,200

The same price of every item in a store is 85% of it usual price. ( please explain your answer because I don’t understand how to

Mademuasel [1]

85% is 0.85 decimals
85 percent of 30
30 * 0.85 = 25.50
30-25.50 = 4.50
Solution: after sale, it is $4.50

Diane works at a gardening store, and today she is helping assemble gas trimmers to be sold. An employee from an earlier shift a

Oxana [17]

The linear function for the number of trimmers assembled is:

y = 7 + 4x.

--------------------------------

A linear function has the following format:

$y = ax + b$

In which:

a is the rate of change.
b is the fixed amount.

--------------------------------

In an earlier shift, 7 trimmers had already been produced, thus 7 is the fixed amount, that is, $b = 7$ .
Diane assembles 4 trimmers per hour, thus the rate of change is 4, that is, $a = 4$
The <u>amount of trimmers y produced after x hours</u> is given by:
