The doubling period of a bacterial population is 15 minutes. At time t = 110 minutes, the bacterial population was 50000.
What was initial population at time t=0?
Find the size of the bacterial population after 4 hours

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

step-by-step explanation:

si si si

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
