Answer:
Step-by-step explanation:
plot five points of f(x)=(1/2)^x
f(0)=(1/2)^0=1
f(1)=(1/2)^1=1/2... through five gives you
y=1, 1/2, 1/4, 1/8, 1/16 for points
(0, 1),(1, 0.5),(2, 0.25),(3, 0.125),(4, 0.0625)
It would be 14.1
6% of 14 is 0.9, so subtracting that from 15 would leave you with 14.1
You have 44$, your brother has 11$.
Let be the amount of money your brother has.
Since you have four times the amount of money your brother has, we can call the amount of money you have .
Thus, you have:
See the attached picture.
a+x+p+8 =r
(to solve isolate x)
x=r-(a+p+8)
x= r-a-p-8
