Answer:

Well, the function is F(x)=x^(2)-6x=C so the domain would be found infinite.

All of the numbers are real except where the expression is undefined but in this case, there is no real number that makes the expression undefined.

Hope this helped, if not, message me and I'll try to explain further.

Illusion [34]

Answer:

24 ft cubed

Step-by-step explanation:

The volume of a rectangular prism is denoted by the formula: $V=lwh$ , where $l$ is the length, w is the width, and h is the height.

Looking at the diagram, we can see that the length is 2 ft (so $l$ = 2), the width is 4 ft (so w = 4), and the height is 3 ft (so h = 3). Now, we can just plug in these values to find V, the volume:

$V=lwh$

$V=2*4*3=24$

Thus, the answer is 24 ft cubed.

Hope this helps!

A building engineer analyzes a concrete column with a circular cross section. The circumference of the column is 18π meters.

Whitepunk [10]

Answer:

$A=81\pi\ m^{2}$

Step-by-step explanation:

Step 1

Find the radius of the circular cross section

we know that

The circumference is equal to

$C=2\pi r$

we have

$C=18\pi\ m$

substitute and solve for r

$18\pi=2\pi r$

simplify

$18=2 r$

$r=9\ m$

Step 2

Find the area of the circular cross section

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=9\ m$

substitute

$A=\pi (9)^{2}$

$A=81\pi\ m^{2}$

Benjamin decides to treat himself to breakfast at his favorite restaurant. He orders chocolate milk that costs $3.25Then, he wan

stepan [7]

Answer:

is the correct answer.

Step-by-step explanation:

As per the question statement:

Cost of Chocolate milk which is ordered already = $3.25.

Benjamin want his bill to be at most = $30

Each stack of pancakes contains 4 pancakes.

Each stack of pancake costs= $5.50

Given that S represents the number of stacks of pancakes bought.

We have, Cost of 1 pancake = $5.50

Now, let us calculate the cost of the number of stacks of pancakes bought.

$\text{Cost of one stack of pancakes}\times \text{Number of stacks of pancakes bought}$

i.e.

$5.50S$

So, total bill = Cost of chocolate milk shake + Money spent on stacks of pancakes = $\$3.25+5.50S$

Now, this money should be lesser than or equal to $30 because maximum bill that Benjamin wants is $30.

So, the inequality can be written as:

$\bold{3.25+5.50S \le 30}$

Determine the mean absolute deviation of the data.9, 7, 11, 10, 8

Darya [45]

Answer:

mean=average which means you add all of the numbers and divide by the number of numbers there are, which sounds pretty confusing, but i'll show you! 9+7+11+10+8=45, now you divide 45 by 5, which is how many numbers there are that we had to add. 45 divided by 5 is 9, which means the MEAN/average is 9!

Step-by-step explanation:

hope this helps!
