Answer:I forgot how to do that one but I had it
Step-by-step explanation:I’m sorry
The formula for compound interest growth is
A=P×(1+r/100)^t
Where
A= end amount
P= principle amount
r= rate
t= time in years
Plug your numbers into the formula:
A=936×(1+(5.5/100))^1
A=$987.48
So the end amount is $987.48
Answer:
Step-by-step explanation:
Given that there are two functions f and g as
![f(x) = \sqrt{x} \\g(x) =4x+9](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Csqrt%7Bx%7D%20%5C%5Cg%28x%29%20%3D4x%2B9)
We have to find the composition of functions.
Composition functions are calculated as the first function inside bracket and then the outside function of answer inside.
a)![fog= f{g(x)} =f(4x+9) = \sqrt{4x+9}](https://tex.z-dn.net/?f=fog%3D%20f%7Bg%28x%29%7D%20%3Df%284x%2B9%29%20%3D%20%5Csqrt%7B4x%2B9%7D)
b) ![gof = g{f(x)} = g(\sqrt{x} )=4\sqrt{x} +9](https://tex.z-dn.net/?f=gof%20%3D%20g%7Bf%28x%29%7D%20%3D%20g%28%5Csqrt%7Bx%7D%20%29%3D4%5Csqrt%7Bx%7D%20%2B9)
c) ![fof = f(\sqrt{x} ) = \sqrt[4]{x}](https://tex.z-dn.net/?f=fof%20%3D%20f%28%5Csqrt%7Bx%7D%20%29%20%3D%20%5Csqrt%5B4%5D%7Bx%7D)
d) ![gog = g(4x+9) = 4(4x+9)+9\\= 16x+45](https://tex.z-dn.net/?f=gog%20%3D%20g%284x%2B9%29%20%3D%204%284x%2B9%29%2B9%5C%5C%3D%2016x%2B45)
Answer:
164 cookies each
Step-by-step explanation:
divide 492 by 3. 3 Because it says Diana and her friends, and 492 because that is the total cookie count.
