I think it’s 90 but not sure
Answer:
Height of plane = 25971.7 meters
Step-by-step explanation:
let H =height of plane
Let x = distance ray to the point under the plane
800 foot = 245meters
1 mile = 1609meters.
Tan 81 =
-----------------------(1)
Tan 67 =
-----------------------(2)
6.3134 =
------------------------(3)
2.3556 =
-----------------------(4)
from (3) and (4)
H = 10158.26 + 6.3134x ---------------(a)
H = 245 + 2.2336x ---------------(b)
equating both (a) and (b) we have:
9913.26 = 3.9576x
x = 2504.74
Subst. x = 2504.74 into (a)
H = 25971.7meters
Answer:
y = 3x + 6
Step-by-step explanation:
The domain is you x values. You need to substitute the x values into both functions to see which one produces the plots on the graph.
<h3>y = 2x + 4</h3>
when x = -3, y = 2(-3) + 4 = -6 + 4 = -2
when x = -2, y = 2(-2) + 4 = = -4 + 4 = 0
when x = -1, y = 2(-1) + 4 = = -2 + 4 = 2
when x = -0, y = 2(0) + 4 = 0 + 4 = 4
<h3>y = 3x + 6</h3>
when x = -3, y = 3(-3) + 6 = -9 + 6 = -3
when x = -2, y = 3(-2) + 6 = = -6 + 6 = 0
when x = -1, y = 3(-1) + 6 = = -3 + 6 = 3
when x = -0, y = 3(0) + 6 = 0 + 6 = 6
The points on the graph are (-3, -3), (-2, 0), (-1, 3) and (0, 6)
This is same as the results from the function y = 3x + 6
