Answer:
Answer
0.109589 millimeters per day.
Explanation
10 mm = 1 cm
4 cm = 4 × 10
= 40 mm
365 days = 1 year
rate to millimeters per day = 40 mm in 365 days
= 40/365 mm/day
= 8/73 mm/day
or = 0.109589 mm/day.
Rate to millimeters per day = 0.109589 millimeters per day.

Answer:
The amount Trevor's family pay per minute on shower water is $0.005.
Step-by-step explanation:
The cost of water is,
Cost = $0.20/liter
Amount of water used over the entire month:
Amount of water used = 72 liters
Compute the total water cost as follows:
Total water cost = Amount of water used × Cost
= 72 × 0.20
= $14.4/liter
The average number of minutes each person showered is:
Average number of minutes = 480 minutes.
The number of people in Trevor's house:
N = 6
Compute the total amount of time the 6 person showered as follows:
Total amount of time = Average number of minutes × N
= 480 × 6
= 2880 minutes
Compute the pay per minute on shower water as follows:
Pay per minute on water = Total water cost ÷ Total amount of time
= $14.4 ÷ 2880
= $0.005
Thus, the amount Trevor's family pay per minute on shower water is $0.005.
Answer:
f(x)= 3(x - 2)(x + 2)
Step-by-step explanation:
The given quadratic function f(x) = 3x^2 - 12
Let's factor the given function.
f(x) = 3x^2 - 3*4
Here the common factor is 3, we can take it as common factor and write the remaining terms.
f(x) = 3(x^2 - 4)
Now we can factor (x^2 - 4) using the formula (a^2 - b^2) = (a-b)(a + b)
(x^2 -4) = (x^2 - 2^2)
= (x - 2)(x + 2)
Therefore, f(x) = 3(x^2 - 2^2)
f(x)= 3(x - 2)(x + 2)
Hope this will help you to understand the concept.
Thank you.
