Answer:
v = 875
Step-by-step explanation:
0.01v + 0.09(8000-v) = 650
Multiply the parenthesis
0.01v + 720 - .09v = 650
Combine like terms
720 - 0.08v = 650
Add 0.08v to both sides
720 = 650 + 0.08v
Subtract 650 from both sides
70 = 0.08v
Divide by 0.08 on both sides
v = 875
Hope this helps :)
we are given with two points: (-8,8) and (0,1). in this case, we are asked for the equation of the line connecting the two. we first solve for the slope that is (8-1)/(-8-0) equal to 7/-8 or -7/8. We substitute to the point-slope form equation y-y1 = m (x-x1) that is y - 1 = -7/8 * x ; y = -7/8 x + 1

Step-by-step explanation:
Answer:
A. 61.82°;
15.64°
B. 33.37°
Step-by-step explanation:
A.
✍️Angle of elevation from 15 ft:
A right triangle is formed. Apply trigonometric ratios formula to find the angle of elevation from 15 ft.
Thus,
Length of the side Opposite to reference angle = 22 + 6 = 28 ft
Adjacent length = 15 ft
Thus, we would have:



(2 d.p)
✍️Angle of elevation from 100 ft:
Thus,
Length of the side Opposite to reference angle = 22 + 6 = 28 ft
Adjacent length = 100 ft
Thus, we would have:



(2 d.p)
B.
✍️Distance you'd be from the screen if you lie on the ground and make an angle of elevation of 40° to the top of the screen:
Adjacent length = your distance from the screen = x
Opposite length = 22 + 6 = 28 ft
Angle of elevation = 40°
Tge trigonometric ratios formula to use would be:

Plug in the values

Multiply both sides by x

Divide both sides by tan(40)

(2 d.p)
You can skip count by ten to go from 240 to 350
Hope it kinda helps
