Hi i need desprate assistance. Two parabolic arches are being built. The first arch can be modelled by the function: y = -x2 + 9. In relation to the first arch, the second arch must span twice the horizontal distance and be translated 6
units to the left and 3 units down. Determine the equation of the second arch.

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.

answer: 0.64
