Use the graph representing bacteria decay to estimate the domain of the function and solve for the average rate of change across the domain.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

it would rotate about 180 degrees.

d 600 because 15*10*2=300

300+300=600
