Don't you mean pi or $\pi$ ? Pie is (usually) edible; pi is not.

If you meant

sin 3 $\pi$
_________________
2

That would be 0/2 = 0.

If you meant sin [3 $\pi$ /2]

that would be -1.

out of 32 students in a class, 5 said they ride a bike to school. based on these results, how many of the 800 students in the sc

Brut [27]

We can write a proportion for this question
5 out of 32 students and we have to find how many (x) out of 800
5/32 = x /800
cross multiply
5*800 = 32x
4000 = 32x
divide both sides by 32
125 = x

About 125 students of the 800 ride their bikes to school.

Hope this helps :)

What is the distance between the points (-4, 6) and (1, -6)?

Oksanka [162]

Answer:

The distance between these 2 points is 13.

Step-by-step explanation:

Picture the 2 points on a graph as a right triangle, where the hypotenuse of that right triangle is the distance between the points. It is very easy to find the length of the legs of that triangle, and you can use those legs to calculate the length of the hypotenuse.

First, find the vertical distance, or the distance between the y-coordinates. Either just look at a graph and count, or subtract them.

$-6-6=-12$

Distance is an absolute value from 0, so -12 is the same as 12.

Next, find the horizontal distance between the x-coordinates.

$1--4=5$

Now, we have the length of the legs, 5 and 12. Use the pythagorean theorem to find the length of the hypotenuse:

$a^2+b^2=c^2\\5^2+12^2=c^2\\25+144=c^2\\c^2=169\\c=\sqrt{169}\\c=13$

The distance between these 2 points is 13.
