Answer:

mCEA = 90ᴼ because CEA is a right angle, and right angles have 90ᴼ measures.

CEF is a straight angle because there are two 90ᴼ angles (CEA and AEF) and therefore there is 180ᴼ in total. A straight line has a measure of 180ᴼ.

AEF is a right angle because if CEA is a right angle and CEF is a straight line, then AEF has to be a right angle.

stich3 [128]

Answer:

The value of y is 6\sqrt{3} units ⇒ 2nd answer

Step-by-step explanation:

In the attached figure

∵ ∠MTN is a right angle

∵ TU is the altitude of the triangle

- There are some rules in this triangle let us revise them

  • (NT)² = NU . NM
  • (MT)² = MU . MN
  • (TU)² = MU . NU
  • TM . TN = TU . MN

∵ NU = 9 units

∵ UM = 3 units

∵ MN = UM + NU

∴ MN = 3 + 9 = 12 units

- By using the 1st rule above

∴ (NT)² = 9 × 12

∴ (NT)² = 108

- Take a square root to both sides

∴ NT = \sqrt{108}

- Simplify the root

∴ NT = 6\sqrt{3} units

∵ NT is y

∴ y = 6\sqrt{3} units

The value of y is 6\sqrt{3} units

The change in water level of a lake is modeled by a polynomial function, W(x). Describe how to find the x-intercepts of W(x) and
andre [41]
If x is time and W(x) is the change in water level at a certain time, then W(x) = 0 indicates when the water level does not change. In other words, the change in water level is 0.

This occurs exactly at the x intercepts as the x-intercepts are points of the form (x,0) where x is some number and the y coordinate is always 0. These special points are also known as roots. The roots or x intercepts are places where the curve crosses the x axis. The handy thing about roots is that they are visually easy to find, and relatively easy to comprehend no matter what math level you deal with. This is why many people of different backgrounds can understand what is going on even if they haven't taken a formal math course (in a while). So if you're giving a presentation, you can simply point to where the roots are and the managers would most likely understand. 

In terms of algebra, it depends on the complexity of the polynomial. For cubics and higher, you'll most likely need a graphing calculator or special software to get the approximate solution. Factoring and using the rational root theorem is a bad idea as it would take a while. It might not even be possible if the roots aren't whole numbers. Thankfully software makes the process relatively painless.

Which of the following is a benefit to using a random sample for an observational study?
Pavel [41]

Answer:

Step-by-step explanation:

Even though no answer choices are given, the main benefit of this is that by choosing a randomly from a population it allows every single individual to have the same chance of getting chosen and observed. This randomness allows for that sample group to much more accurately represent the entire population that is being observed without having to conduct additional research. Therefore, becoming extremely useful in such studies.

Rachel has 24 red candies and Maya has 18 green candies. They want to arrange the candies in such a way that each row contains e
oksano4ka [1.4K]

Answer: 6 candies per row.

Step-by-step explanation:

The restrictions that we have are:

Each row has the same number of candies.

Each row has only one color of candy.

We want to find the largest possible rows.

We have 18 green candies and 24 red candies.

Now, to arrange them in rows of equal numbers, we should find a common factor between 18 and 24. (particularly, we want to find the largest common factor between 18 and 24).

Now, to find common factors we first take the smaller number, and we divide it by different numbers, starting by 2 (we want to divide by small numbers, so the result will be the largest factor)

18/2 = 9.

Now to see if 9 is also a factor of 24, we see if the quotient between 24 and 9 is a whole number.

24/9 = 2.66

This is not a whole number, so 9 is not a common factor.

Now we divide by the next number, 3.

18/3 = 6.

24/6 = 4.

So 6 is a common factor of 18 and 24.

Then each row will have 6 candy.

And we will have:

18/6 = 3 rows of green candy.

24/ = 4 rows of red candy.
