Answer:
Composition of f and g = 6x + 7
Composition of g and f = 6x + 11
Step-by-step explanation:
f(x) = 2x + 3
g(x) = 3x + 2
f(g(x)) = 2(g(x)) + 3 = 2(3x + 2) + 3 = 6x + 4 + 3 = 6x + 7
g(f(x)) = 3(f(x)) + 2 = 3(2x + 3) + 2 = 6x + 9 + 2 = 6x + 11
A. in 11 years it will be reduced to 858.99, in 10 it will be reduced to 1,073.
b. 43 years
Given that the bag contains 5 apples and 3 oranges, if you select 4 pieces of fruit without looking, the number of ways you can get 3 apples is given by:
we can select 3 apples in 5C3 ways but we are selecting 4 pices, this means that one orange can be selected in 3c1 ways. Using product rule, the total ways to select four pices is
5C3*3C1
=5!/[3!*(5-1)!]×3!/[1!(3-1)!]
=120/(6×2!)*6/(2!)
=12×3
=36
54/3= 18
18•2=36
36+18=54
The shortest piece is 18in
