You rrr meh herooozz! puhleaszeee its 10:

11.5 is not the answer btw(got it wrong)

Step-by-step explanation:

Modeling With Functions

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
