Answer:
Solution : Option B, or 9π
Step-by-step explanation:
We are given that y = x, x = 3, and y = 0.
Now assume we have a circle that models the given information. The radius will be x, so to determine the area of that circle we have πx². And knowing that x = 3 and y = 0, we have the following integral:
So our set up for solving this problem, would be such:
By solving this integral we receive our solution:

As you can tell our solution is option b, 9π. Hope that helps!
Answer:
Slope = 1/2
y-intercept = 30
Equation : y = 1/2x + 30
D. 150 miles
Step-by-step explanation:
We can use the two visible points you marked on the graph.
They are (0,30) which is also the y-intercept and (20,40).
Calculate change of y over change of x.
10/20 or 1/2
So the slope is 1/2 and the y-intercept is 30.
Therefore, using y = mx + b form, the equation is y = 1/2x + 30
Then, to find how many miles you drove if the cost was $105, we can plug in 105 for y in the equation.
105 = 1/2x + 30
75 = 1/2x
x = 150
0.00373134328
I think you can round that but I think that's the answer.
Answer:
C
Step-by-step explanation:
A is for sure wrong because we can see the distribution of the data showing us that the center is at 8. B is also wrong because the spread is only from 6.5 even though the table goes from 5. C would be correct because its symmetrical in shape.
