Calculate the average rate of change of

Mathematics
1 answer:
Arlecino [84]3 years ago
6 0
Avg rate of change is given by change in f(x) over change in x, in other words:

\displaystyle \frac{f(x_2)-f(x_1)}{x_2-x_1}, x_2 > x_1

Substituting the function and your values of x gives:

\displaystyle \frac{f(3)-f(-5)}{3-(-5)} = \frac{(-3(3)^2+4(3))-(-3(-5)^2+4(-5))}{8} = \frac{-15+95}{8} \\
= \frac{80}{8} = \boxed{10}

What are the two solutions of 2x^2=-x^2-5x-1
hammer [34]

Answer:

x = 5/-6 + (√13)/-6

x = 5/-6 -(√13)/-6

Step-by-step explanation:

2x^2 = -x^2 - 5x - 1. Subtract 2x^2 from both sides.

-3x^2 - 5x - 1. Do the quadratic formula.

That gives you:

-5/6 ± (√13)/-6.

Since the triangles are similar, they will have proportional sides. With this knowledge, we can make the proportion \frac{8}{10} =\frac{x}{5} to solve for x.


Firstly, cross multiply: 40=10x


Next, divide by 10 on both sides, and your answer will be 4 = x, or the first option.

Julie tips the ball over the net in a volleyball game. The graph shows the quadratic function that represents the height of the
Andrew [12]

We are given a graph for the height of the ball with respect to horizontal distnace x of the ball from Julie.

From the graph, we can see the position of Julie is at (0,0). And starting height of the ball when thrown is 6 feet.

Then it moved to the maximum height of 14 feet. And hit to the ground when it has position on x-axis is 3.5 feet.

<em>Because we can see the parabola is crossing x-axis at 3.5 on the right.</em>

<em>That represents distance of the ball from Julie when it hit to the ground.</em>

<h3>Therefore, it has a horizontal distance of 3.5 feet from Julie.</h3>
