Find the distance and midpoint of a segment with the following endpoints: (5,-1) and (-9,-1)

Likurg_2 [28]

Answer:

$d = 14$

$(-2,-1)$

General Formulas and Concepts:

Order of Operations: BPEMDAS
Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
Midpoint Formula: $(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Step-by-step explanation:

Step 1: Define

(5, -1)

(-9, -1)

Step 2: Find distance d

Substitute: $d = \sqrt{(-9-5)^2+(-1-(-1))^2}$
Simplify: $d = \sqrt{(-9-5)^2+(-1+1)^2}$
Subtract/Add: $d = \sqrt{(-14)^2+(0)^2}$
Evaluate: $d = \sqrt{196}$
Evaluate: $d = \14$

Step 3: Find Midpoint

Substitute: $(\frac{5-9}{2},\frac{-1-1}{2})$
Subtract: $(\frac{-4}{2},\frac{-2}{2})$
Divide: $(-2,-1)$

This year Sheila earned 8.00$ an hour. This year she earns 10.00$ an hour. What is the percent increase in the amount Sheila ear

yulyashka [42]

Answer: It is a 25% increase.

Step-by-step explanation: First lets subtract her new wage from her old wage. 10 - 8 = 2

Next, lets write an percent equation, for p = percent.

2 = p x 8

Basically, we are saying that her new wage will be what percent of her old wage.

Next,

2/8 = p

0.25 = p

Now, multiply 0.25 by 100 to get a percent

0.25 x 100 = 25

So her new wage is a 25% increase from her old wage.
