Find the distance between (1, 4) and (-2, 0)

Mathematics
1 answer:
Vanyuwa [196]2 years ago
4 0

Answer:

\boxed {d = 5}

Step-by-step explanation:

Use the <u>Distance Formula</u> to help you determine the distance between two given points:

d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}

First point: (x_{1}, y_{1})

Second Point: (x_{2}, y_{2})

-Apply the two given points onto the formula:

First point: (1, 4)

Second point: (-2, 0)

d = \sqrt{(-2 - 1)^{2} + (0 - 4)^{2}}

-Solve for the distance:

d = \sqrt{(-2 - 1)^{2} + (0 - 4)^{2}}

d = \sqrt{(-3)^{2} + (-4)^{2}}

d = \sqrt{9 + 16}

d = \sqrt{25}

\boxed {d = 5}

Therefore, the distance is 5.

DO THE MATH
lesantik [10]

f(p) where p is the price in thousands. f(250) means the average number of days before being sold for $250,000. Lets take a look at the answers and see which fits the best:

1. The house sold for $250,000. (This is what the 250 stands for, but we need to find what f(250) means and not just 250)

2. The house stayed on the market for an average of 250 days before being sold. (Nope, not even close)

3. This is the average number of days the house stayed on the market before being sold for $250,000. (Yes! This seems right, f(250) is the average number of days before being sold for $250,000)

4. The house sold on the market for $250,000 and stayed on the market for an average of 250 days before being sold. (Nope, we are not told anywhere that it takes 250 days to be sold)

This means that our answer has to be 3) This is the average number of days the house stayed on the market before being sold for $250,000.

I hope I've helped! :)

Find the value of x.<br><br> A.<br> 7<br> B.<br> 9<br> C.<br> 11<br> D.<br> 12
Arisa [49]
Use the law of cosines to solve for angle A. Plug your known side length values into the equation a^2 = b^2 + c^2 – 2bc cos A.

Then use the law of sines to find angle B. (Sin A/a = Sin B/b = Sin C/c).

Because the two red angles within B are congruent, divide your angle measure in half.

From there, do the law of sines to solve for x. Good luck!

Help pls! this is due tonight. thanks!
erma4kov [3.2K]

Answer:

Neon: 0

Oxide:  -2

Copper:   2

Tin:  0

Step-by-step explanation:     To solve you must add/subtract the numbers to get the charge, for example if its -30 charge from electrons and 10 charge from protons, -30 + 10 = -20     therefore the charge is -20

A political pollster conducted a study to determine political party loyalty. To do so, he selected a random sample of 100 regist
Reika [66]

Answer: (a)

P - Value = 0.0981 is high, this indicates stronger evidence that we should fail to reject the null hypothesis: H0: pD = pR (There is no significant difference between the proportion of Democrats who plan to vote for the Democratic candidate in the upcoming election and the proportion of Republicans who plan to vote for the Republican candidate in the upcoming election). P - Value = 0.0981 is the probability of obtaining results at least as extreme as the observed results of the Hypothesis Test, assuming that the null hypothesis is correct.

(b)

Since P - Value = 0.0981 is greater than \alpha = 0.05, the difference is not significant. Fail to reject null hypothesis.

(c)

Since in the Hypothesis Test, we have failed to reject null hypothesis, we could have made: Type II Error: Failure to reject a false null hypothesis. One potential consequence of this error is as follows:

Suppose in reality there is significant difference between the proportion of Democrats who plan to vote for the Democratic candidate in the upcoming election and the proportion of Republicans who plan to vote for the Republican candidate in the upcoming election. But the political pollster wrongly concludes that there is no significant difference between the proportion of Democrats who plan to vote for the Democratic candidate in the upcoming election and the proportion of Republicans who plan to vote for the Republican candidate in the upcoming election. Type II Error is committed in this situation. The consequence of this Type II Error is that the political pollstar will that the political parties are loyal and will not do any follow up work whereas in reality it is not so.
