C since y-x are being subtracted and there should be another subtraction but there isnt
First one b ≤ 9 good luck
The growth of the bacteria is expressed as:
<span>B(t) = 4 e^0.8t
</span>
where t is the time in units of hours. If the bacteria is allowed to grow for 8 hours then the number of bacteria present would be,
<span>B(t) = 4 e^0.8(8)
</span><span>B(t) = 2407</span>
Answer:

Step-by-step explanation:
Volume of a cylinder is given by cross sectional area multiplied by height hence
V=Ah
Since the cross sectional area of

Substituting the formula for A into formula for volume then

Substituting 8ft for r and 20 ft for h then

Rounded off to the nearest tenths, the volume is equivalent to
