In a lab experiment, 2200 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 26 hours. How many bacteria would there be after 17 hours, to the nearest whole number?

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
