H/1000 = tan(65°)
h = 1000*tan(65°) ≈ 2145 . . . . ft
The helicopter is about 2145 ft high.
Right answer is B. If we have f equal the amount of her remaining way so f it will be the difference between the way she has gone and her finish line. So we have 70 in the approximate middle of her way and F is between 70 feet and 105 feet, so 105=70+F
Answer:
Step-by-step explanation:
Note that the sine wave is shifted up by 1/2 and the peak is at 5/2 so subtract the 1/2 from the 5/2 to get the amplitude of this wave.
It's 2
Step-by-step explanation:
it's obviously the equation is equals to zero,
-12x + 16 = 0
-12x = -16
-12. 12
like terms cancel each other to remaining with x
thus,
x = 4/3
<h2>AND</h2>
4x - 12 = 0
4x = 12
4. 4
like terms cancel each other to remaining (make x subject of the formula) with x
thus,
x = 3
Answer:
y = 16
Step-by-step explanation:
The slope of GH is ...
G -H = (14, 11) -(8, -13) = (6, 24) = (Δx, Δy)
slope = Δy/Δx = 24/6 = 4
The perpendicular line through F will have a slope of the negative reciprocal of this, or -1/4. The point-slope form of the equation can be written as ...
y -k = m(x -h) . . . . . line with slope m through point (h, k)
The perpendicular line through F is then ...
y -13 = (-1/4)(x -6)
For an x-value of -6, the value of y will be ...
y = (-1/4)(-6 -6) +13 = 12/4 +13 = 16
The value of y so that EF is perpendicular to GH is 16.
