Answer:
Step-by-step explanation:
12 + 4c + c = c + 4
12 + 5c = c + 4
12 + 4c = 4
4c = -8
c =-2
Answer: 6.6
Step-by-step explanation:
We have two triangles. Find the hypothenuse of the first triangle to make it easier to solve the second triangle.
First triangle:
a = 6
b = 8
c = ?
Use pythagorean's theorem


This hypothenuse is valid for both triangles. Having said this, we already have 2 sides of the second triangle; c and a. We need to find b.


Okay, here we have this:
Considering the provided angle, we are going to calculate the requested cosine, so we obtain the following:
Then to obtain the cosine we will review the following image of the unit triangle:
So since pi radians is equal to 180°, we can see in the image that the cosine of 180 degrees is equal to -1, so we finally get that the cosine of the angle is -1.

Step-by-step explanation:
Outliers can affect the slope of a line of best fit.
Step-by-step explanation:
Outliers are observed data points which are far from the least-squares line.They contain large errors.They occur as a result of incorrect data.Outliers have a big effect on the slope of a regression line.
