A spotlight has a beam that travels 93 feet and covers an area intercepted by an 76 degrees angle, as shown below

Answer:

B: 5/13

Step-by-step explanation:

pythagoras theorem: a^2 + b^2 (sides) = c^2 (hypotenuse)

a^2 + 12^2 = 13^2

a^2 + 144 = 169

a^2 = 25

a = 5

sin = opp/hyp

sin 5/13

Hope this helps

Answer: 2 cups

Step-by-step explanation: Olivia spends 4$ and nothing more. 1$ is her profit that can continue to gain and can be represented as 1x or x. x-4 is the equation to represent her profit. Nathan spends 5$ and 0.50$ is his profit which can be shown as 0.5x. 0.5x-5 is the equation to represent his profit.

Set those two equations equal to each other.  [tex]0.5x-5=x-4[/tex]

Isolate x.   [tex]0.5x=-1[/tex]

Solve for x.  [tex]x=-2[/tex]

Since x represents the amount of cups sold, you cannot have a negative amount of cups sold. Therefore, Olivia and Nathan must sell 2 cups to make the same profit.

Answer:

x = 17.32

y = 10

Step-by-step explanation:

USsing the SOH CAH TOA identity

sin theta = opp/hyp

sin 30 = y/20

y = 20sin30

y = 20(0.5)

y = 10

Using Pythagoras theorem to get the value of x

20^2 = x^2 + y^2

400 = x^2 + 10^2

400 - 100 = x^2

300 =x^2

x = √300

x = 17.32

Answer:

x = 17.32 ,y = 10

Step-by-step explanation:

Use ratio of cosine :-

Use ratio of sine :-

Part (a)

Why not? Because we can locate the tallest building without having to gather a sample and computing any statistical values based on the sample data. Note how we have one single building and we're focused on just that building only. We aren't asking anything about a population of buildings. Statistics is the science of trying to measure a population in some way, often through the use of a sample statistic. For example, if we asked "what is the average building height in Chicago, Illinois?", then we would be asking a statistical question. Ideally, we would measure every single building in the city. Of course, that's very time consuming and impractical. So the next best thing is to randomly select a sample of buildings and try to estimate the average height like that.

Once again, we're only focused on one single building and not several. So we don't do the operations of gathering a sample and we aren't doing any statistics here. We're simply measuring the building, or looking up the building height in some records database.

=============================================================

Part (b)

The population is the set of teenagers. This could be narrowed to just the teens in one specific town, county, or regional area. It doesn't make much sense to extend the population out too far because teens too far away would likely not visit this particular mall in question. Let's say the population is every teen in a certain county. We have a lot of people in this population, so we'll have to gather a sample. Doing a census is too time consuming and expensive. This process of gathering a sample points to this question being a statistical one. We don't know which store is the most popular, but we can get a fairly good idea through the sampling process. It won't be a 100% guarantee that we got the right one considering that again the sample isn't the exact population, but we should get close if we did the sampling right.

Note how the variable in question is a qualitative one. The store names are the categories or names that the teens select in the survey. This data type is nominal and not ordinal, since stores do not have an inherent rank (other than alphabetical but that's not of much importance). Also note that the responses for this random variable are, more or less, random in nature. We simply don't know how the teens will respond assuming we go into this completely blind. It's a good idea to do so to avoid bias. This random nature helps add evidence we have a statistical question here. The random variable value is not set in stone like the tallest building is. Keep in mind that the question for part (a) is asked to refer to a very specific narrow window of time. The same can be said for part (b) as well. Be sure to carefully set up the question and avoid any ambiguity.

To summarize, to answer such a question given to us we would need to gather a sample and compute sample statistics. This is why we have a statistical question here.

Answer:

Step-by-step explanation:

Yes it's a function.

You may be looking at v which produces m

You may be looking at r which also produces m.

That's fine. Two different x values (the domain) can produce the same y value. Lots of functions do that. (you'll study parabolas pretty soon and all that open up or down have two x values producing the same y value).

If you have a member of the domain producing 2 y values,  that doesn't work. That would not be a function.

This example is a function.

Answer:

do you have a picture to help?

The measure of angle 6 in the transversal that cut the parallel lines is 57 degrees

When a transversal line cut parallel lines, the angles formed are corresponding angles, alternate angles, vertically opposite angles etc.

Therefore,

∠2 = 180  - 123 = 57° (angle on a straight line)

Therefore,

∠2 ≅ ∠6 (corresponding angles)

Hence,

∠6 = 57 degrees
