ASAP please help This graph shows how many cookies Julia makes over 9 days.

a) How many total cookies will Julia have on
day 7?

b) Estimate the output when the input is 2.

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
