Arecording studio charges musicians an initial fee of $60 to record an album. studio time costs an additional $75 per hour. which function represents the total cost in dollars, c(t), of recording an album as a function of studio time in t hours?

a) c(t) = 60t - 75

b) c(t) = 75t - 60

c) c(t) = 60t + 75

d) c(t) = 75t + 60

D

Step-by-step explanation:

slope= 75

y-intercept= 50

substitute 75 for m in mx+b and 50 for y in mx+b

C(t) = 75t + 60

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.
