4a^2-2b^2+40 a=2. b=7

-92

Step-by-step explanation:

4a^2-2b^2+40 a=2. b=7

Fill in variables

4(2)^2-2(7)^2+40      a=2. b=7

8^2 - 14^2 + 40

64 - 196 +40 = -92

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
