Answer:

$y=\frac{3}{2}x+4$

Step-by-step explanation:

So the line C equation is $y=\frac{3}{2}x+2$ and line D is parallel to it and it passes through the point (4,10) and we need to ding the equation for line D.

So first we have a graph with line C listed and (4,10).

And we can keep listing more equations till we find the right one which is $y=\frac{3}{2}x+4$ .

So I got this by knowing that in parrelel lines the slope is the same but the y intercept changes which is why it was fast to find the answer.

A surveyor wishes to determine the height of a mountain. At a given position he measures the angle of elevation to the top as 43

Usimov [2.4K]

Answer:

4,486.93 ft

Step-by-step explanation:

Let 'h' be the height of the mountain and 'x' be the horizontal distance between the first position measured and the top of the mountain.

Two right triangles can be modeled such that their tangent relationships yield:

$tan(43.66) = \frac{h}{x}\\tan(38.2) = \frac{h}{x+1000}$

Solving the linear system:

$x= \frac{h}{tan(43.66)}\\x = \frac{h}{tan(38.2)} -1000\\\frac{h}{tan(43.66)}=\frac{h}{tan(38.2)} -1000\\1000 = 0.222869*h\\h=4,486.93\ ft$

The mountain is 4,486.93 ft high.
