Answer:
<u>h = V/r²</u>
Step-by-step explanation:
The formula is :
- V = r²h (actually 1/3πr²h in real life)
Solving :
- Dividing both sides by r²
- V/r² = r²h/r²
- <u>h = V/r²</u>
Answer:
<em>Ct = 4075 + 368d</em>
Step-by-step explanation:
<u>Function Models</u>
A company rents out food booths and game booths at the county fair.
For a food booth, the company charges a fixed fee of $175 and a variable fee of $10 per day. If d is the number of days, then the charges for a food booth are:
Cf = 175 + 10d
Similarly, the company charges $50 plus $9 per day for a game booth, thus the total charges are:
Cg = 50 + 9d
If all the booths are rented for the entire time, the total amount the company is paid for 17 food booths and 22 game booths is:
Ct = 17Cf + 22Cg
Substituting:
Ct = 17(175 + 10d) + 22(50 + 9d)
Operating:
Ct = 2975 + 170d + 1100 + 198d
Simplifying:
Ct = 4075 + 368d
Answer:
a) 
b) The pollution level at 4 o'clock in the afternoon is of 280 parts per million.
Step-by-step explanation:
The pollution level in the center of a city at 6 am is 30 parts per million and it grows in linear fashion by 25 parts per million every hour.
This means that the pollution in t hours after 6 am is given by:
, which is the answer to question a.
b. The pollution level at 4 o'clock in the afternoon
4 in the afternoon is 10 hours after 6 am, so this is y(10).
The pollution level at 4 o'clock in the afternoon is of 280 parts per million.
