You're gonna use the sine trig function to find the length of the shadow

sin26 / 1 = 43 / x; now you cross multiply

sin26 x = 43; divide both sides by sin26

x = 43 / sin26

x = 98 which is the shadow

Hope this helps!

The equation of the parabola is:

$y = 24x^2$

---------------------------

The <em>equation </em>of a parabola of vertex (h,k) and focus (0,f) is given by:

$y = 4p(x - h)^2 + k^2$

Vertex at the origin means that $h = 0, k = 0$ .
Focus (0,6) means that $p = 6$

Thus, the equation of the parabola is:

$y = 4p(x - h)^2 + k^2$

$y = 4(6)(x - 0)^2 + 0^2$

$y = 24x^2$

siniylev [52]

Answer: C (4,7)

Points are labeled as (x,y)

If the unknown point is 4 units away from the origin on the x axis, x will be 4

If the unknown point is 7 units away from the origin on the y axis, y will be 7

Therefore (4,7)
