Answer:
![r=\sqrt {I}+10](https://tex.z-dn.net/?f=r%3D%5Csqrt%20%7BI%7D%2B10)
Step-by-step explanation:
We first need to know the square root of I then add 10 on that square root since r is 10 more than the square root of I
Therefore,
![r=\sqrt {I}+10](https://tex.z-dn.net/?f=r%3D%5Csqrt%20%7BI%7D%2B10)
There is no rate of change of Function 1. It's slope(rate of change) is zero.
Function 2 has a slope of 2.
Do you know your places? Like tenth place?
The answer for your question is 686
20% of 124.95 is close to $125 so that is equal of 12.50 of 10% so multiply by 2 which is $25.00 so the estimate discount of the jacket will be $25.00
