<span>rotated 90° about the origin
(x,y) = (-y, x)
so </span><span>(5, -2) is rotated 90° about the origin = (2, 5)
answer
</span><span>b.(2, 5)</span>
Answer:
4,886.83feet
Step-by-step explanation:
The question will result in a right triangle with
Opposite = distance of the balloon above the ground = 950feet
Angle of elevation = 11 degrees
Required
Horizontal distance h (adjacent)
Using SOH CAH TOA identity
Tan theta =opp/adj
Tan 11 = 950/h
h = 950/tan 11
h = 950/0.1944
h = 4,886.83feet
Hence the horizontal distance from the balloon to the ground crew is 4,886.83feet
The Answer To This Problem is: C.-4
V=πr2hWhen r=radius and h=height
Answer:
i think its B
