To calculate the are of the sides of a cylinder, you take the circumference of the base, or circle, and multiply it times the height. To calculate the circumference of a circle we use the formula 2*pi*r, or 15pi. We multiply this times 20 to get 300pi cm. If you are using 3.14 for pi, this is 942, or if you are using actual pi, around 942.4777.
Answer:
- 5 min: 3,029,058
- 10 min: 3,398,220
- 60 min: 10,732,234
Step-by-step explanation:
The given function is evaluated by substituting the given values of t. This requires using the exponential function of your calculator with a base of 'e'. Many calculators have that value built in, or have an e^x function (often associated with the Ln function).

<h3>5 minutes</h3>
The number of bacteria present after 5 minutes is about ...
f(5) = 2.7×10^6×e^(0.023×5) ≈ 3,029,058
<h3>10 minutes</h3>
The number of bacteria present after 10 minutes is about ...
f(10) = 2.7×10^6×e^(0.023×10) ≈ 3,398,220
<h3>60 minutes</h3>
The number of bacteria present after 60 minutes is about ...
f(60) = 2.7×10^6×e^(0.023×60) ≈ 10,732,234
Three hundred nine thousand and seventeen
Answer:
Geometric Sequence
Step-by-step explanation:
As you can see, the terms are of consecutive sequences.
The 3rd term ÷ The 2nd term = 3
The 4th term ÷ The 3rd term = 3
The ratio between the consecutive terms is the same. Therefore, it's a geometric sequence.
Answer:
It would take them 6 minutes to paint the wall and 12 to paint the other half : 18 minutes
Step-by-step explanation:
Say that the student who can paint a wall in 12 minutes is painting half of the wall it would take them 6 minutes
As the other student who can paint the same wall in 24 minutes also paints half of a wall it would take that person 12 minutes.
