An employee at a garden center fills a water tank once a day around noon to a height of 20 inches. The function M models the height of the water in the
tank, M(x), in inches, x seconds after 12:00 p. m. on Monday as it fills. The
function T gives the height of the water in the tank, T(2), in inches, x
seconds after 12:00 p. m. on Tuesday as it fills. Here are the equations and
graphs of M and T.
M(x) = 575

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

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.
