You are being asked to make π the subject in

C=2πr \:

So divide both sides of the equation by
2r

That is

\frac{ C}{2r} = \frac{2πr}{2r}
The you have
\frac{ C}{2r} = \pi

or

\pi = \frac{ C}{2r}

I hope this is helpful?

Select the correct texts in the table.
ra1l [238]

Based on the given texts in the table about the graph of the function, the true statements are:

  • The graph crosses the y-axis at (0,-15).
  • The graph has a point of discontinuity at x = -2.
  • The graph is increasing over the interval (4, ∞o).
  • The domain of the function is all real numbers.

<h3>Which statements are true of the graph of the function?</h3>

The function, 4x - 15 shows that 15 is the y-intercept which means that the graph will cross the y-axis at (0,15).

The point of discontinuity is x = - 2 and we see this with the gap created at x < -2 and -2 ≤ x ≤ 4.

The graph is indeed increasing over the interval (4, ∞o) because any value of x that is greater than 4 will increase f(x) = 3^x^-^4.

The domain of the function is also all real numbers as it begins at negative infinity and ends at infinity, (-∞, ∞).

When estimating a job to bid, a contractor’s estimator first determines the actual cost of labor using the function
CaHeK987 [17]

Answer:

M(B(h))=78.18025h

Step-by-step explanation:

First we have the following equations:

L(h) = 28.75h         eq. 1

B(L) = 1.78L            eq. 2

M(B) = 1.43B           eq. 3

To find the selling price based on the estimated number of hours, we need to start replacing equation 1 in equation 2 as:

B(L) = 1.78*B  

B(L(h)) = 1.78*(28.75h)

B(L(h)) = B(h) = 51.175h       eq. 4

Finally, if we weplace equation 4 in equation 3, we get:

M(B) = 1.43B

M(B(h)) = 1.43*(51.175h)

M(B(h)) = 73.18025h

So, the composite function that can be used to find the selling price for the labor portion of a bid based on the estimated number of hours is:

M(B(h)) = 73.18025h
