4. (08.02 hc) the function f(x) = −x2 + 44x − 384 models the daily profit, in dollars, a shop makes for selling cake ball combos, where x is the number of combos sold and f(x) is the amount of profit. part a: determine if this function has a maximum or a minimum value. how did you know? (2 points) part b: determine the vertex. what does this calculation mean in the context of the problem (hint: compare the profit they are making (f(x)) vs. the sales ( show your work for finding the vertex. (4 points) part c: determine the x-intercepts. what do these values mean in the context of the problem? show your work for finding the x-intercepts. (4 points)

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.
