Which note could be modeled by the function y=sin pi/62 0.

A. middle C
B. D-flat

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

what is the rest of the question? ?

1. supplementary angles

2. acd and bcd

step-by-step explanation:

the answer, i believe is y-8=1(x+4)
