Assuming you meant
Then you can compose the function g(x)
With the function
Because f (g(x) ) means that you first find (calculte)
and second you divide 7 by g(x) to obtain 7 / [√(8x+10) ].
For this case we must find the product of two mixed numbers:
So, we have:
If we go to a mixed number we have:
Answer:
Answer:
the answer for this question is c
Answer:
21 ft by 66 ft
Step-by-step explanation:
From the question,
P = 2(L+W)............... Equation 1
Where P = Perimeter of the playing Field, L = Length of the playing Field, W = width of the playing Field.
If the Length of the Field is 45 ft longer than the width,
L = 45+W............ Equation 2
Substitute Equation 2 into equation 1
P = 2(45+W+W)
P = 90+4W............. Equation 3
Given: P = 174 ft.
Substitute into equation 3
174 = 90+4W
4W = 174-90
4W = 84
W = 84/4
W = 21 ft.
Substituting the value of W into equation 2
L = 45+21
L = 66 ft.
Hence the dimensions of the playing field is 21 ft by 66 ft
