Answer:
Y = x^2/2 - 2x - 2
Step-by-step explanation:
You have to build the triangles.
They are such that:
h is the common height
x is the horizontal distance from the plane to one stone
Beta is the angle between x and the hypotenuse
Then in this triangle: tan(beta) = h / x ......(1)
1 - x is the horizontal distance from the plane to the other stone
alfa is the angle between 1 - x and h
Then, in this triangle: tan (alfa) = h / [1 -x ] ...... (2)
from (1) , x = h / tan(beta)
Substitute this value in (2)
tan(alfa) = h / { [ 1 - h / tan(beta)] } =>
{ [ 1 - h / tan(beta) ] } tan(alfa) = h
[tan(beta) - h] tan(alfa) = h*tan(beta)
tan(beta)tan(alfa) - htan(alfa) = htan(beta)
h [tan(alfa) + tan(beta) ] = tan(beta) tan (alfa)
h = tan(beta)*tan(alfa) / (t an(alfa) + tan(beta) )
She can move the decemal place 2 places to the right because a centimeter is 100 times smaller than a meter. so it would be 785 centimeters

Answer:
dC = 2.44
Relative error = 19%
Step-by-step explanation:
Δv = 3 ; ΔT = 1 , v = 23, T = 8
Use differential Calculus
Relative Error
dC / C @(T = 8, v=23) * 100 = 19 %
