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

A small town's phone numbers either begin 373 or 377. How many phone numbers are available?
ser-zykov [4K]

Answer:

  • <u><em>There are 20,000 number available.</em></u>

Explanation:

To determine <em>how many phone numbers are available </em>you need to know how many digits the number contains.

I will assume the same number of digits for other similar questions, i.e. 7.

With 7 digits, the numbers that begin with 373 or 377 can be of the form 373XXXX or 377XXXX.

Where each X can be any digit 0 - 9. Then, there are 10 different options for each X.

Thus, there are 10×10×10×10 = 10,000 different numbers starting with 373 and other 10,000 different numbers starting with 377.

In total, there are 20,000 numbers available.

What are some prime numbers to create a product of four
Alex_Xolod [135]
Since a product in maths means the result after multiplying numbers, you need to multiply 2 prime numbers and get 4.

If we look at the prime numbers: 2, 3, 5, 7, 11, etc, we see that the only number we can multiply to get 4 is 2, or, in other words, the only multiplication of prime numbers we can do to get four is 2*2=4.

Answer:

To find out the range, you check the minimum and maximum of the graph, and then check the y-component of these minimum and maximum.

You would get the minimum(-6, -6), and maximum(3, 4), get the y-component of these two points, you got the range: -6 to 4

Hope this helps!
