Answer:
B
Step-by-step explanation:
Given
f = c / λ ( multiply both sides by λ )
fλ = c
Let that number be x.
"I multiply a number by four" Can be represented by 4x.
"Then I add one" means that to 4x, you added 1. So it's 4x + 1
"The answer is 33" So 4x + 1 = 33.
We need to solve for x.
4x + 1 = 33
First, subtract 1 from each side to have the variable on a side and the number on the other:
4x + 1 - 1 = 33 - 2
4x = 32
Divide both sides by 4 to get the variable x alone on a side and its value on the other side:
(4x)/4 = 32/4
x = 8
You can recheck your answer (very important):
4x = 8*4 = 32
4x + 1 = 32 + 1 = 33
The answer has been approved.

Answer:
this is quite easy. if the tire is 14 ft. tall, that would mean the diameter is 14 ft. as well (do to a tire being round). the radius is half of the diameter, meaning the radius is 7 ft. finally, to find the circumference, you would have to multiply pi by 2 (6.28) then multiply this by the radius to make 43.98 ft.
Step-by-step explanation:
D = 14
R = 14/2 = 7
C = 2(pi) x 7 = 6.28 x 7 = 43.98

Using the exponential model given, the number of bacteria in the culture after 9 minutes after the observation began will be 4789
<u>Given the exponential model</u> :
- <em>t = number of minutes after observation begins </em>
<u>The number of bacteria in the culture 9 minutes after the observation began can be calculated thus :</u>
<em>Substitute 9 for t in the exponential equation :</em>
Therefore, the number of bacteria in the culture after 9 minutes will be about 4789
