Answer:

You work at the local pool. The pools cleaners have emptied the pool and you need to refill it. The pool is a rectangular prism with a height of 10 ft, a length of 40 ft, and a width of 10 ft. Whats the volume of the pool so you can figure out how much water needs to go in it.

When asked to write the domain for the equation y= |x - 6| + 3, Mary wrote the Domain is y < 3. What mistake(s) did Mary make

castortr0y [4]

Answer:

Ok, the domain is the set of values that we can input in a function.

In this case, we have:

y = Ix - 6I + 3.

Notice that there is no restriction here, x can actually take any value, then the domain will be the set of all real numbers.

The correct domain is x, x ∈ R

Now, if we had (for example) something like:

y = Ix - 6I < 3

Now we have a restriction in the domain because we can not have y equal or larger than 3.

To find the domain, we can break the absolute value:

Ix - 6I < 3

is equivalent to:

-3 < x - 6 < 3

now let's add 6 in each side.

-3 + 6 < x - 6 + 6 < 3 + 6

3 < x < 9

That will be the domain in that case.

I NEED HELP PLEASE! ITS DUE TOMORROW!! THANKS!

Answer:

Katie is not cheating. From the question, it sounds like Katie's spinner is 1-12. James has two dice so he has two sets of each number 1-6. This means that Katie can roll two numbers greater than six but James can only roll up to six. Using probability, I think there is a 50% chance that Katie's number will be bigger than James every time she spins. A fairer way would be for them both to play with the same dice or spinner.

Does a polygon usually have more sides or more angles

xxTIMURxx [149]

I've seen this question on Brainly before, and I always shake my head.

Please think about this for a few seconds. Maybe even make some
scribbles on a piece of paper.

-- A triangle has 3 sides and 3 angles.

-- A square, rectangle, rhombus or parallelogram has 4 sides and 4 angles.

-- Draw anything with 5 sides. It doesn't have to be pretty, and they don't
all have to be the same length or anything special. Just draw any shape
with 5 sides. Count the angles, and you'll find that there are five of them.

By now you should be starting to get the creepy hunch that maybe a
polygon always has the SAME number of sides and angles. I hope so.
That's the correct creepy hunch.

You can get all kinds of hunches, and even work most of them out,
just by using your thinker for a while.
