Answer:

Answer:

2nd graph (in the attached pics)

Step-by-step explanation:

Graphically, the x-intercepts of the graph of a quadratic function are its zeroes.

There can be

no zeroes (where graph doesn't cut the x-axis at all),

1 zero (where graph touches the x-axis at one point only), and

2 zeros (where the graph cuts the x-axis at 2 points)

Looking at the figures, the 2nd graph has no real zeroes, because the graph doesn't cut the x-axis at all!

So, the answer is the second graph.

Step-by-step explanation:

Rainbow [258]

Let the number of hour it took them to have completed the same number of problems be x, then
15 + 10x = 9 + 12x
12x - 10x = 15 - 9
2x = 6
x = 6/2 = 3

After 3 hours, they must have completed the same number of homeworks.

A circle has a diameter of 29 feet. What is the area? *

11111nata11111 [884]

Answer:

The answer is

<h2>660.5 square feet</h2>

Step-by-step explanation:

Area of a circle = πr²

where r is the radius

From the question

diameter = 29 feet

To find the radius given the diameter we use the formula

$radius = \frac{diameter}{2} \\ radius = \frac{29}{2} \\ = 14.5 \: \: feet$

So the area of the circle is

$A = {14.5}^{2} \pi \\ = 210.25\pi \\ = 660.519...$

We have the final answer as

<h3>660.5 square feet</h3>

Hope this helps you

Use the following graph of the function f(x) = 2x3 + x2 − 3x + 1 to answer this question: graph of 2x cubed plus x squared minus

Zina [86]

Answer:

Step-by-step explanation:

f(x) = 2x^3 + x^2 − 3x + 1

f'(x) = 6x^2 + 2x − 3

The slope at -2:

f'(-2) = 6(-2)^2 + 2(-2) − 3

f'(-2) = 24 + -4 − 3

f'(-2) = 17

-----

The slope at 0:

f'(0) = 6(0)^2 + 2(0) − 3

f'(0) = − 3

The average rate of change is (17+(-3))/2, or 14/2, or 7
