The average rate of change of f from 2 to 3

ella [17]

For a function of $f$ , the average rate of change can be found as follows:

$ARC=\frac{f(x_{2})-f(x_{1})}{x_{2}-x_{1}}$

So, this problem asks for the Average Rate of Change of $f$ from $x_{1}=2$ to $x_{2}=3$ . In this way, we need to find $f(x_{1}) \ and \ f(x_{2})$ . As you can see above, we have the graph of $f(x)$ , so we can find these values. Thus, from the graph:

$f(x_{1})=4 \\ f(x_{2})=1$

Therefore:

$ARC=\frac{1-4}{3-2} \\ \\ \therefore \boxed{ARC=-3}$

What is the volume of a cone that has a radius of 12 m and a height of 3 m?

vfiekz [6]

452.16 m^3
1/3 = 0.333333333
0.333333333 * 3.14 = 1.046666667
1.046666667 * 144 =150.72
150.72 * 3 = 452.16

As the earth rotates, it travels a distance of 80 miles in 5 minutes. At this constant rate, which equation best represents y, t

solniwko [45]

Answer:

y=16x

Step-by-step explanation:

So, you are given the equation as if y=total distance the earth travels in x minutes. If you are given that you travel 80 miles in 5 minutes, you can plug these value into the variables they are representing and solve for the constant.

Visual:

y=xk y=miles x=minutes k=constant

Plug in your values and you get:

80=5k

Now, you solve for k by diving 5 on both sides, which leaves you with k=16.

Now you plug your value for k into the original equation, leaving you with y=16x
