Step-by-step explanation:
<u>Modeling With Functions
</u>
We have a table of values of speeds vs distance taken for a car to stop. We are required to find a model that uses the square root and fits the given data to predict other values of d as a function of v.
By the nature of the problem, we can know that for v=0, d must be 0 too. So our model won't include a vertical shift or independent term. Being v the speed of the car and x the distance it takes to stop, we use the following model

We must find A to make the function fit the data. Let's use the first point (v,x); (20,9)

Solving for A


Then we have

Evaluating for v=35


Last option
its a fraction which is not in the answer choice

Step-by-step explanation:
Answer:
25%
Step-by-step explanation:
If we consider the original price of the piece of suit is x.
Given that, on Monday during a one day sale, the price of the suit was decreased by 20%.
Therefore, the new price of the suit on Monday is
.
Now, the price of the suit on Tuesday was changed back to the original price i.e. x.
Therefore, the price is increase by (x - 0.8x) = 0.2x from the price of 0.8x.
So, the percentage change in price of the suit on Tuesday is
%. (Answer)
