The first week is 10 x 1.4.
The second week is that answer x 1.4 etc.
So you are only multiplying the first week by 10.
{ [ 10 x 1.4) x 1.4] x 1.4}. Since multiplication is commutative, we don’t need the grouping symbols...
10 x 1.4 x 1.4 x 1.4
That s answer A
Answer:
G(x) = (1/2)(1/(x +5)^2 -4
Step-by-step explanation:
G(x) = bf(x -h) +k
represents the function f(x) shifted right h units, up k units and scaled vertically by a factor of b. Your problem statement tells you ...
f(x) = 1/x^2, b = 1/2, h = -5, k = -4
so your G(x) is ...
G(x) = (1/2)(1/(x +5)^2 -4
