1320 ways
This can be solved using something called permutation. There are 12 possible swimmers that can be in first place. After that, 11 swimmers left to be in second place. Finally there are 10 swimmers left for third place. Multiply these together you get 12•11•10=1320. Hope this helps!!

What if this function simplified?
almond37 [142]

Hi!

Let's first expand the cotangent of theta.

You'll probably know that tangent will be "y/x", or \frac{sin(x)}{cos(x)}, and cotangent is the reciprocal of this, meaning that it is "x/y" or \frac{cos(x)}{sin(x)}.

That means that we are now given this equation.

cos(x)\frac{cos(x)}{sin(x)}+sin(x)

That'll multiply to:

\frac{cos^2(x)}{sin(x)}+sin(x)

We'll want a common denominator to add by multiplying sin(x) to both top and bottom of the second term:

\frac{cos^2(x)}{sin(x)}+\frac{sin^2(x)}{sin(x)}

\frac{cos^2(x)+sin^2(x)}{sin(x)}

Pythagorean Identity states that sin^2(x)+cos^2(x)=1, so substitute that in:

\frac{1}{sin(x)}

Which simplifies to:

csc(x)

Hope this helps!

What is 5/2 - 1/3 = 1/3y
kati45 [8]

5/2 - 1/3 = 1/3y

I would convert the denominators to 6 to make this easier like this

15/6 - 2/6 = 2/6y

Now you can subtract easily like so

13/6 = 2/6y

Now divide

y = 13/6 divided by 2/6

To divide fractions do keep (numbers) change (sign) and flip (numbers)

y = 13/6 x 6/2

Now multiply:

78/12 = 6 1/2 = 6.5

y = 6.5 is your final answer!
