Answer:
A. & B.
Step-by-step explanation:
General form is ax2 + bx + c = 0.
Must contain an x2 term
Must NOT contain terms with degrees higher than x2 eg. x3, x4 etc
At least, less than, more than, equal, no more than, etc
B = (1/6).π.x².s
1st Multiply both sides with 6 → 6B = (6).(1/6).π.x².s. Simplify by 6
6B = π.x².s. Now divide both sides by .π.x².
6B/(.π.x²) = .(π.x².s)/(.π.x²) After simplification you get:
6B/(.π.x²) = s → s = 6B/(.π.x²)
16 ounces = 1 pound
meaning 2.5 pounds is added to the skull, 602.5 pounds.
Answer:
Function: 
Amount earned for 10 hours of work: 
Step-by-step explanation:
Let be "x" the number of hours worked on a project and "y" the total amount Luigi charges for a project.
Based on the data given in the exercise, you can identify that:
- $140 is a fixed amount.
- For each hour worked on the project, Luigi charges $25. This can be expressed as:

Then, the total amount he charges for a project is the sum of $140 and
. This can be represented with the following function:

To calculate the amount of money earned for 10 hours of work, you must substitute
into the function and evaluate. Then:
