Let theta be an angle. Then there exists constants a and b such that cos(theta + 60) = a*sin (theta) +b*cos (theta) for all theta. Enter a, b in that order.

you are saying it as if a fact, not a question, but yes, you would be correct? ; )

step-by-step explanation:

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

$15.40 per mile

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4
