Step-by-step explanation:
n(h)=36h because there are 3 dozen cupcakes made per hour, to get C(h) you just plug in 36h in place of n and simplify, and then for the final answer 2 is plugged into the equation from the second answer.
Answer:
The world population will be 11.64 billions in 21 years.
Step-by-step explanation:
Initial population = 8 billion
Growth rate = 1.8% per year =0.018
Time = 21 years
We are supposed to find what will the world population be in 21 years
Formula : 
y = population after t years
r = rate of interest in decimals
t = time in years
Substitute the values :


Hence the world population will be 11.64 billions in 21 years.
Hello!
To solve this exercise, let's think a bit and choose the best option for each alternative.
<h2>(a) Karen's desk is about 3...</h2>
Well, a desk with 3mm or 3cm is too small, and with 3km is too big.
In this case, the best option is 3 meters (even though it's big, it's the best option).
<h2>(b) Dan's refrigerator has a mass of 80...</h2>
Usually, a refrigerator is heavy. So the best option is kilograms.
<h2>(c) The bucket holds about 5... of water.</h2>
5ml of water is too little, it fits in a spoon. The correct option is liters.
Answers:
a. meters
b. kilogr
Answer:
Step-by-step explanation:
A(1) = 9
A(n+1) = A(n) - 5
n = 1 ; A(1+1) = A(1) - 5
A(2) = 9 - 5
A(2) = 4
n = 2 ; A(2+1) = A(2) - 5
A(3) = 4 - 5
A(3) = 1
n = 3 ; A(3+1) = A(3) - 5
A(4) = 1 - 5
A(4) = -4
n = 4 ; A(4+1) = A(4) - 5
A(5) = -4 - 5
A(5) = -9
First four terms are: 9 , 4 , 1 , -4 , - 9
