Answer:

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
Answer:
3 or 3/1
Step-by-step explanation:
count the rise over run from exact pints, I used (-1,3) ans (-2,0)
Answer:
Step-by-step explanation:
a) 3x^2-12x-11=3*x^2-3*2*2*x+3*4-23=3*(x^2-2*2x+2^2)-23=3*(x-2)^2-23
so a= -2 ,b= -23
b) x1=[12+V(12^2-4*3* -11)]/6=12/6+V(144+132)/6=2+2/6V69=2+1/3V69=
2+V69/9=2+V23/3
c=2, d= 23/3
