Answer:

Slope is y2-y1/x2-x1

Let’s make x1 and y1 (6,8)

Let’s make x2 and y2 (2,1)

1-8/2-6

-7/-4

Both are negative numbers, which cancel each other out, making the fraction a positive number.

7/4

A. Would be your answer

Hope I helped!

Answer:

A. 7/4

Step-by-step explanation:

To find the slope when we have 2 points, we use the formula

m = (y2-y1)/(x2-x1)

where (x1,y1) and (x2,y2) are the given points

m = (1-8)/(2-6)

= -7/-4

=7/4

Answer:

Option c. 30,000

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

Let

y ----> safe load in pounds

x ----> length in feet of a horizontal beam

we have

For $x=15\ feet, y=2,000\ pounds$

Remember that

$k=y*x$

substitute

$k=2,000*15=30,000$

Complete the following sentence. The coefficient of determination between the dependent variable, TEST SCORE, and the independen

amm1812

Answer: a. variation in the variable, HOURS SPENT STUDYING explains 43% of the variation in the variable. TEST SCORE

Step-by-step explanation:

The coefficient of determination is denoted by R square is the proportion of the variance in the dependent variable that is predictable from the independent variable.

Given: dependent variable = TEST SCORE

independent variable = HOURS SPENT STUDYING

coefficient of determination = 0.43

That means variation in the variable, HOURS SPENT STUDYING explains 43% of the variation in the variable. TEST SCORE.

Hence, the correct option is a.

What is the magnitude of the position vector whose terminal point is (6, -4)?

Marysya12 [62]

Answer:

2√13

Step-by-step explanation:

The distance formula is useful for this. One end of the vector is (0, 0), so the measure of its length is ...

d = √((x2 -x1)² +(y2 -y1)²) = √((6 -0)² +(-4-0)²)

= √(36 +16) = √52 = √(4·13)

d = 2√13 = |(6, -4)|
