A wooden roller coaster contains a run in the shape of a sinusoidal curve, with a sorios of hills. The crest of each hill is 102 feet above the ground. If it takes a car 1.9 seconds to go from the top of a hill to the bottom (12 feet off the ground), find a sinusoidal function of the form y - Asin (-2) + B that models the motion of the coaster train during this run starting at the top of a hill.

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

c.   x=2.4cm

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.
