Answer:
This does represent an exponential function , because his savings increase by a constant rate
Step-by-step explanation:
Let
x -----> the number of weeks
y ----> the amount saved
In this problem we have a exponential function of the form
where
a is the initial value
b is the base
r is the rate of change
where
---- because he doubles the amount each week
---->
substitute
therefore
This does represent an exponential function , because his savings increase by a constant rate

Answer:
7^5
Step-by-step explanation:
7x7x7x7x7 is equal to 7^5. Depending on how much sevens there are, that is the power number. In this case there are 5 sevens so that means it is 7^5.

Answer:
44%
Step-by-step explanation:
Solution:
Calculate percentage change
from V1 = 2000 to V2 = 1120
(V2−V1)|V1|×100
=(1120−2000)|2000|×100
= −8802000×100
= −0.44×100
= −44%change
= 44%decrease
Answer:
119
Step-by-step explanation:
I believe you meant the question to be " + 1 / , if m - 1 / m = 3. "
I presume that we want to take this second equation at hand here, and " simplify " it further. After doing so this first expression will have a value with respect to the simplified value of the equation, and, plugging in it's value we can solve for the expression ( + 1 / . )
m - 1 / m = 3 - Take each value squared on either side of the equation,
- Simplify,
If you don't know how to expand expressions such as the one in the third step, " " here is a quick recap. Remember that . Therefore,
Now let's continue,
- Add 2 on either side,
_______________
So now we have the " simplified equation " as you can say, for the equation. Let's " simplify " the expression now,
- Substitute the value of 11,
Solution = 119
