The rays MR and MP intersects at the point M, this means the point M is the vertex of the ∠2.
Another name for ∠2 is ∠PMR.
For this case we have the following equation:
Where, by definition, we have the following variables:
d (x): the daily expense per truck (in dollars)
x: the daily mileage
Therefore, the domain of the function is given by:
Equivalently:
[0, ∞)
Answer:
The input for the function includes all positive real numbers
option d.
Rachel spends 6 hours 45 minutes a week trying to learn to play the violin.
Step-by-step explanation:
Step 1; Rachel learns for 45 minutes a day from Monday through Friday and in the weekend she learns to play the violin for one and a half hours. So she learns for the following periods of time
Monday - 45 minutes
Tuesday - 45 minutes
Wednesday - 45 minutes
Thursday - 45 minutes
Friday - 45 minutes
Saturday - 90 minutes (60 × 1.5 hours)
Sunday - 90 minutes (60 × 1.5 hours)
Step 2; To determine how much time she practices in a week we just add the individual times she plays on each day.
Total time practices in a week = 45 + 45 + 45 + 45 + 45 + 90 + 90 = 405 minutes = 6 hours 45 minutes.
