Answer: a) 6, 0, 10       b) yellow/orange line  

Step-by-step explanation:

a) Plug the x in the y functions, y = 2x² + x

when x = -2, y = 2(-2)² + (-2) = 8 - 2 = 6

when x = 0, y = 2(0)² + (0) = 0 + 0 = 0

when x = 2, y = 2(2)² + (2) = 8 + 2 = 10

b) By looking the table, the equation has a point (0,0), only blue and yellow/orange line has the passed the point (0,0), so we delete the red line option.

And we choose a point (1,3), then only yellow/orange line has passed the point (1,3). So the yellow/orange line fits the equation.

The triangle shown below has an area of 32 units^2
Lorico [155]

Answer: Varies, missing side lengths could be 1, 2, 4, 8, 16, 32, 64, choose the one that works BEST for answering your problem, as there was no image

Step-by-step explanation:

for the triangle to have an area of 32, the "square" that it would make when multiplying the area by 2 would be 64...

so factors of 64 are 1, 2, 4, 8, 16, 32, and 64.

1 and 64 don't seem like good dimensions for the triangle, but could work

2 and 32 is another possibility

4 and 16 can work too

8 and 8 also is possible...

so pluging the lengths into the formula for a triangle...

(b* h)/2 should get you to 32.

How to find sin A, sin (90°-A), and tan A?
finlep [7]

1) sin(90 - A) = cos A=√(2/3) or √6/3

2) sin²A + cos²A=1

sin²A= 1 -cos²A=1 - (√2/3)²= 1 - 2/3= 1/3

sin A = 1/√3 or √3/3

3) tan A= sin A/ cos A= (1/√3)/(√2/√3)= 1/√2

tan A = 1/√2 or √2/2
