Answer:

r=d/t

Step-by-step explanation:

Step 1: Flip the equation.

rt=d

Step 2: Divide both sides by t.

rt/t=d/t

r=d/t

Find the greatest common factor of the<br> following monomials:<br> 36m3n4. 2m5n3. 4m6n6
melisa1 [442]

Answer:

2m^3n^3

Step-by-step explanation:

Let us start with the number parts

36 , 2 and 4

2 is common here as it can divide all

The smallest m factor is m^3 so it is common for all

The smallest n factor is n^3 which is also common for all

So, we have the greatest common factor as;

2 * m^3 * n^3 = 2m^3n^3

M 1 = (2x + 28)<br> m 3= (6x + 4)<br> What is m&lt;2<br> Enter your answer in the box.
s2008m [1.1K]

Answer:

m∠2 = 140°

Step-by-step explanation:

m∠1 = m∠3, since they're vertical angles.

Solve for x:

2x+28=6x+4\\24=4x\\6=x

Plug in 6 for x for either m∠1 or m∠3. Doesn't matter since they're equal.

m∠1 = (2(6) + 28)°

m∠1 = (12 + 28)°

m∠1 = 40°

Now that we know m∠1, we can now solve for m∠2.

m∠1 + m∠2 = 180°

40° + m∠2 = 180°

m∠2 = 140°

This table represents a quadratic function with a vertex at (1, 1). What is the
erastova [34]

The average rate of change on the interval (5, 6) is 9. So the correct option is D.

<h3>How to find the average rate of change on the interval?</h3>

Here we want to find the average rate of change of f(x), the function on the table, on the interval (5, 6).

This is just:

r = \frac{f(6) - f(5)}{6 - 5}

f(x) = a*x^2 + b*x + c

I we look at the table we see that:

f(1) = 1 = a + b + c

f(2) =2 =  4a + 2b + c

f(3) = 5 = 9a + 3b + c

This is a system of equations.

If we subtract the second and first functions, we get:

2 - 1 = (4a + 2b +c) - (a + b + c)\\1 = 3a + b = a + b + c

From that we take two relations:

1 - 3a = b\\2a = c

Now we can replace these two in the last equations so we get:

5 = 9a + 3b + c\\\\5 = 9a + 3*(1 - 3a) + 2a\\\\5 = 9a + 3 - 9a + 2a\\\\5 = 3 + 2a\\\\5 - 3 = 2a\\\\2 = 2a\\\\a = 1

Now that we know the value of a:

c = 2a = 2*1 = 2\\\\b = 1 - 3a = 1 - 3 = -2

The quadratic equation is:

f(x) = x^2 - 2x + 2

Evaluating this in x = 6 we get:

f(6) = 6^2  - 2*6 + 2 = 26

And from the table we know that f(5) = 17, then the average rate of change is:

r = \frac{f(6) - f(5)}{6 - 5} = \frac{26-17}{1} = 9

The correct option is D.
