140*.20=28
140-28= $112
so, the current price is $112
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.

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.
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
