Answer:
0.46 per donut. 46 cents
Step-by-step explanation:
5.49/12=0.4575
Rounding to the nearest cent is about 46 cents per donut.
After calculation, the composite function f(g(0)) returns the value 2 as the response.
Given, the values of the functions are:
f(x) = √₋x₊1 and g(x) = ₋x₋3
we need to find f(g(0)) = ?
F of g of x is another name for a composite function. Normal representations include f(g(x)) or (f g)(x), which denote that x = g(x) should be used in place of f(x). While the function g (x) is referred to as an inner function, the function f (x) is referred to as an outer function.
It means that every instance of an x in the function f is replaced with the function g(x).
∵ g(x) = ₋x₋3 so we can substitute this in the following expression:
g(0) = -(0) ₋ 3
g(0) = ₋3
Now in place of g(0) we can write ₋3, hence the changed expression becomes:
f(g(0)) = f(₋3)
= √₋(₋3)₊1
= √4
∴ f(g(0)) = 2
Hence we get the calculated function value as 2.

Answer:
D) 82 units
Step-by-step explanation:
ΔBCD ≅ ΔEFG
In congruent triangles, corresponding parts are congruent
BD = EG
4x - 9 = 2x + 15
4x - 9 -2x = 15
2x - 9 = 15
2x = 15 +9
2x = 24
x = 24/2
x = 12
EG = 2x + 15 = 2*12 + 15
= 24 + 15
EG = 39 units
FE = CB = 17 units
Perimeter of ΔEFG = FE + EG + GF
= 17 + 39 + 26
= 82 units
