An ice cream factory makes 170 quarts of ice cream in 2 hours. how many quarts could be made in 12 hours? what was that rate per day?

The vertex of this parabola is at (-2,-3). when the x-value is -1, the y-value is -5. what is the coefficient of the squared expression in the parabola's equation?

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b

Which is an x-intercept of the graphed function? (0, 4) (–1, 0) (4, 0) (0, –1)
