Answer:

Step-by-step explanation:
The radius, r of the expanding circle of oil is modeled by the function:
, where s is time in seconds.
When s=5
Radius 
Area of a circle 
Therefore, the area of the oil spill when s=5 seconds

The area of the spill when s=5 seconds is 45pi square inches.
Is there supposed to be a graph or a “circle”? you kinda need it to solve the problem lol
Answer:
the slope for x is 1 and the slope for f(x) would be 7
Step-by-step explanation: the y intercept for x is 5 and for f(x) it would be 25
Answer:
B. (-1, 0)
General Formulas and Concepts:
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
- Solving systems of equations using graphing
Step-by-step explanation:
To find the solution set of a systems of equations, the point where the 2 lines intersect would show the solution for the systems.
According to the graph given, both lines intersect each other at x = -1.
Therefore, our answer is B.
