Use the quadratic formula to solve the equation. If necessary, round to the nearest
hundredth.
A model rocket is launched from a roof into a large field. The path of the rocket can be
modeled by the equation y = -0.04x4 + 8.3x + 4.3, where x is the horizontal distance, in
meters, from the starting point on the roof and y is the height, in meters, of the rocket
above the ground. How far horizontally from its starting point will the rocket land?
11.64 m
0 0.52 m
416.03 m
208.02 m

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
