The angle of depression is
tan^-1 3/7 = 23.2 deg
Answer:
140%of minutes
Step-by-step explanation:
Answer:
Let b = profit on a blue car
w = profit on a white car
r = profit on a red car
b = w + 10 (1)
r = w - 7 (2)
2r = b -2
2r-b= -2 (3)
Subtract eq. (2) by 2q. (1)
r - b = 0 - 7 - 10
r - b = -17 (4)
Subtract eq. (3) by eq. (4)
r - 0 = -2 - (-17)
r = 15
in eq (2)
r = w - 7
15 = w - 7
w = 22
in eq (1)
b = w + 10
b = 22 + 10
b = 32
The profit on a blue car is $32
Step-by-step explanation:
THE ANSWER IS 32
If it doubles every 4 hours, in 12 hours you will have 3 doublings.
2 * 2 * 2 = 8
90*8 = 720 pounds of algae
Find slope by calculating rise over run (can pick whatever points are easiest for you). I'm choosing (0,2) and (-3,0)
(0-2)/(-3-0)
(-2)/(-3)
2/3
Slope=2/3
Y intercept is the value of y when x is 0. We can look to see the y intercept is 2.
Final answer: D
