I'm am almost 100% positive that the answer is d
Answer:


Step-by-step explanation:
Let's rewrite the equation as:

Now, let's find its derivate:

Let's evaluate x=0.27 and x=2:


Keep in mind that when we derivate A(average speed) we find the average acceleration, thats why the result is given in mi/h^2, also it explains the minus sign, because for every stop you make on the trip you are decelerating.
It should be roughly 50.27? when finding the area of a circle, be sure to use a=πr^2!
First convert from standard to slope intercept form.
3x+4y=12
4y=-3x+12
y=-3/4x+3
The slope should be -3/4 and the y intercept should be 3.
Final answer: D
