Since the order of selection does not matter, we will use combinations to solve this problem.

We are to form the combination of 30 objects taken 6 at a time. This can be expressed as 30C6.

$30C6= \frac{30!}{6!*24!} \\ \\ 
= 593775$

This means the six teachers can be selected in 593775 ways.

So the correct answer is option A

Function h models an object's height in feet after x seconds have passed. Which equation shows that the object's height increase

ASHA 777 [7]

Answer:

Step-by-step explanation:

We know that function <em>h</em> represents an object's height in feet after <em>x</em> seconds.

In that case, option A) h(15) = 100 means that after 15 seconds, the object's height is 100 feet.

Option B) h(100) = 15 means that after 100 seconds, the object's height is 15 meters.

Therefore, neither A nor B are correct.

Option C) h(15) - h(0) = 100 means that between the zeroth and 15th second, their difference is 100 feet.

In other words, the object's height increased by 100 feet over the first 15-second period.

Option C is correct.

For Option D), it gives us the average rate of change. (h(15) - h(0)) / (15) = 100 means that for the first fifteen seconds, the height of the object increased at an average rate of 100 feet per second.

At each mile marker for the first five miles of a marathon, Ellie was 18 seconds, 9 seconds, 14 seconds, 6 seconds, and 3 second

mixas84 [53]

The mean is the average.

Let A = mean

A = (18 + 14 + 9 + 6 + 3)/5

A = 50/5

A = 10

Ellie's mean time is 10 seconds.

The table below shows the squares of different numbers:

gogolik [260]

The table in Part A represents y as a function of x. This means that the value of Y is dependent on the value of X. The table can be represented by an equation that describes the relation of X and Y:
$y = x^{2}$ or $f(x) = x^{2}$
By substituting any value of X, you get a specific value of Y based from the given relationship, thus Y is a function of X.

For Part B, the value of f(150) is $470 and it represents the total cost for borrowing a rowboat for 150 hours. By substituting the value of x = 150 into the function, you get the total cost:
$f(x) = 20 + 3x \\ where \\ x = 150 \\ f(150) = 20 + 3(150) \\ f(150) =20 + 450 \\ f(150) = $ 470$
