Answer:
b
Step-by-step explanation:
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
It’s a because 5x6 then you add 6x5 to get your answer boom
The direct relationship between the original distance and the resulting distance is y = 3 · x.
<h3>What is the relationship behind a given statement and graph?</h3>
In this problem we find the case of a direct relationship, that is, a linear relationship between two b. According to this case, the original distance (d), in yards, is directly proportional to the resulting distance (d'), in feet.
y = k · x
Where:
- x - Original distance, in yards.
- y - Resulting distance, in feet.
- k - Proportionality constant, in feet per yard.
If we know that x = 1 yd and y = 3 ft, then the proportionality constant is:
k = y / x
k = 3 ft / 1 yd
k = 3 ft / yd
The direct relationship is y = 3 · x.
