There are 25 questions on your math test. You have completed 5 questions so far. What fraction of the total questions do you sti
maksim [4K]

Answer:

\frac{4}{5}

Step-by-step explanation:

If you have completed 5 questions, you still have 25-5=20 more questions to answer. We need to find what fraction 20 is of 25, if that makes sense. A fraction is simply a part over a whole. In this case, the part is 20 and the whole is 25. Therefore, the fraction we are looking for is \frac{20}{25}, which simplifies to \frac{4}{5}. Hope this helps!

Which formula gives the x-coordinates of the maximum values for y = cos(x)?
solong [7]

We have been given a function y=\cos(x). We are asked to find the formula which gives the x-coordinates of the maximum values for given function.

We know that cosine function oscillates between -1 and 1 that is minimum value of cosine is -1 and maximum value is 1.

We also know that \cos(0)=1 and after period of cosine is 2\pi. This means after every 2\pi, we will get to 1.

So maximum of cosine is 2\pi n, where n is an integer.

Therefore, our required formula is 2\pi n, where, n=0,\pm 1,\pm 2,\pm3,...
