If the sin 0° = 0, then which statement is true?

cos 90° = 1, because the cosine and sine are complements
cos 180° = 1, because the cosine and sine are supplements
cos 90° = 0, because the cosine and sine are complements
cos 180° = 0, because the cosine and sine are supplements

Which expression is equivalent to 2x^2+7x+4?

For which pairs of functions is (f•g)(x)=12x? f(x)=3-4x and g(x)=16x-3 f(x)=6x2 and g(x)= 2/x f(x)= and g(x) = 144x f(x)=4x and g(x) =3x

If the car had not hit the fence, how much farther would it have skidded? solve the skid-distance formula to find the extra distance that the car would have traveled if it had not hit the fence. round your answer to two decimal places. note that unit conversion is built into the skid distance formula, so no unit conversions are needed.
