Answer:
See below.
Step-by-step explanation:
A. k = 50 * 3.6 = 180.
B. The equation is y = 180/x.
C. When x = 75, y = 180/75
= 2.4.
D. Checking C: 2.4 = 180/75 = 2.4. Correct
Answer:
83.2 cm^2
Step-by-step explanation:
To solve this we're going to find the area of the bigger triangle (the shaded and unshaded parts together) and then the area of the smaller triangle (the unshaded part) and then subtract that from the area of the bigger triangle. We're going to use the equation: Area=1/2 x base x height. So the base of the big triangle is 16, and the height is (10.4+8.6 = 19). Put into the equation this looks like this: Area=1/2 x 16 x 19, so by multiplying we find that the area is 152 cm^2. Next we find the small triangle's area, Area=1/2 x 16 x 8.6, so the area is 68.8. Then to find the area of the shaded part, we subtract the unshaded area (68.8) from the whole area (152), 152-68.8=83.2.
W² - v + 1
(-2)² - (-8) + 1
4 + 8 + 1 = 13
B.13 is your answer
(two negatives = one positive)*
(plug in -2 for w, and -8 for v)
(is that w², or do you mean 2w?)
