The perimeter of the triangle is 21.4 units

<h3>How to determine the perimeter?</h3>

The points are given as:

A(−2,2), B(5,−3), and C(−4,−1)

Calculate the side lengths using:

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

So, we have:

AB = \sqrt{(-2 -5)^2 + (2 + 3)^2} = 8.6

AC = \sqrt{(-2 +4)^2 + (2 + 1)^2} = 3.6

BC = \sqrt{(5+4)^2 + (-3 + 1)^2} = 9.2

The perimeter is then calculated as:

P = AB + AC + BC

This gives

P = 8.6 + 3.6 + 9.2

Evaluate

P = 21.4

Hence, the perimeter of the triangle is 21.4 units

by solving the first equation you'll get x= -24/13

if you solve the second option (B) then you'll the same result i.e x=-24/13

so option C is correct

mrs_skeptik [129]

Answer:

2:15 PM

Step-by-step explanation:

When the plane arrives in Seattle, the time in eastern time period would be 5:15 PM.  From eastern to pacific, the time goes back 3 hours. 5:15 - 3 hours is 2:15. Since the time is still in the afternoon, it is still PM.

In a simple regression analysis (where y is a dependent and x an independent variable), if the slope is positive, then it must b
Scorpion4ik [409]

Answer:

c. there is a positive correlation in-between x and y

Step-by-step explanation:

A regression line is a line that suggests that all the points in a scatter diagram lie on or near one particular line. In a simple regression analysis in which y is the dependent variable and x is the independent variable. If the slope is positive, the bivariate data is also said to have a positive correlation. The positive correlation in-between two variables x and y implies that in general, an increase in x goes hand in hand with an increase in y.

Which function is quadratic?
PilotLPTM [1.2K]

Answer:

step 1. A, B,D are incorrectly written as these are not all coordinates. they must be written (x, y)

step 2. so the question becomes is C a quadratic

step 3. The x values must be evenly spaced. the x values are evenly spaced by a difference of 4

step 4. write out the y values: -126, -14, 2, 18

step 5. write out the differences: 140, 16, 16

step 6. write out the differences: -124, 0.

step 7. after doing this twice the numbers nust be the same for this to be a quadratic which they aren't

step 8. C is not a quadratic.
