Answer:
strong negative correlation
Step-by-step explanation:
if x goes up y goes down and if y goes up x comes down
Answer:
Triangle 1: x = 80 degrees, acute
Triangle 2: x = 10 degrees, right
Step-by-step explanation:
Triangle 1:
By the Sum of Interior Angles Theorem, all the angles inside the triangle adds up to 180 degrees. So, set up this equation:

Solve for x:

So, x = 80 degrees
Because all the angles are less than 90 degrees, this is an acute triangle.
Triangle 2:
By the Sum of Interior Angles Theorem, all the angles inside the triangle adds up to 180 degrees. So, set up this equation (with the right angle given):

Solve for x:

So, x = 10 degrees
Because there is an angle measuring 90 degrees, this is a right triangle.
Answer:
162
Step-by-step explanation:
Step 1: Define
x⁴ + 9x²
x = -3
Step 2: Substitute and Evaluate
(-3)⁴ + 9(-3)²
81 + 9(9)
81 + 81
162
Similar polygons only differ by a scaling factor. In other words, two polygons are similar if one is the scaled version of the other.
In particular, this implies that the angles are preserved, and the correspondent sides are in proportion.
These two polygons are both rectangles, so the angles are preserved. We must check the sides, and we have to check if the smaller sides are in the same proportion as the bigger sides.
So, the two rectangles are similar if the following is true.

In any proportion, the product of the inner terms must be the same as the product of the outer terms:

This is clearly false, and thus the two rectangles are not similar.
