Find the slope of a line that contains the two points (-2,8) and (1,2)

kifflom [539]

Answer:

$m = -2$

Step-by-step explanation:

Slope Formula: $m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}$

Points: (-2, 8), (1, 2)

$m = \frac{8-2}{-2-1}$

$m = -2$

A passenger escalator travels from the first floor to the fifth floor a distance of 10 m in 10 seconds what is the escalator spe

Mumz [18]

It is presumed that the 10m is the vertical distance in 4 floors so 10meters divided by 10 seconds is 1m/second is the average speed of the escalator. Hard to add anything to this to make up to the required 40 words.

Eight expressions are given below. Determine whether each expression is equivalent to 5^10 or not equivalent to 5^10.

KengaRu [80]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the 8 expressions are not given.

The general explanation is as follows

As complex as an expression may seem, you have to simplify each expression until it cannot be further simplified.

Then you categorize each result, depending on if it equals $5^{10}$ or not

Take for instance:

$5^5 * 5^5$

Using law of indices:

$5^5 * 5^5 = 5^{5+5$

$5^5 * 5^5 = 5^{10$ ---- equivalent

$\frac{5^5 + 5^5}{2 * 5^{-5}}$

Factorize the numerator

$\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5(1 + 1)}{2 * 5^{-5}}$

$\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5 * 2}{2 * 5^{-5}}$

Cancel out 2

$\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5}{5^{-5}}$

Apply law of indices

$\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5--5}$

$\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5+5}$

$\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{10$ ---equivalent

$125 * 78125$

Express as exponent

$125 * 78125 = 5^3 * 5^7$

Apply law of indices

$125 * 78125 = 5^{3+7$

$125 * 78125 = 5^{10$ ---- equivalent

$5^3 + 5^7$

Solve exponents

$5^3 + 5^7 = 125 + 78125$

$5^3 + 5^7 = 78250$ ---- not equivalent

4’1” - 1’ 10” whats is

cluponka [151]

Since inches are out of 12 this would be

4 ft - 1 ft = 3 ft

3' 1" - 1 " = 3 '

3 feet is also 2 ft and 12 inches

2' 12" - 9 " = 2' 3"

So the answer is 2 feet and 3 inches

Hope this helps
