What do you think?

I'm helping my brother with his math hw and I think there is some rule for what sin(x^2) is but I can't remember. Either that or as it relates to differentiating sin(x^2). Do we even care that x is being squared when inside the sin function as opposed to sin^2(x)?

When you use the quotient rule to find the derivative of a function, does the denominator of the function have to have a variable or can it be a constant number?

40% of the students are REGISTERED to vote. 60% of those prefer candidate A and 40% prefer candidate B.

60% are NOT REGISTERED to vote. 30% prefer candidate A and 70% prefer candidate B.

if there are 10 REGISTERED voters, what is the probability of getting 2-5 (two to five) votes for candidate B? (there is only one answer)

any help would be appreciated. thanks in advance

People laugh at me when I tell them that within 25 years we will find the secret to immortality because of great advances in science and medicine. I know that to a lot of people it sounds crazy. I'm a tech buff and I;m always looking stuff up online. I just think that in the next 25 years or so we will have so many great things. Like cars that drive themselves, affordable space tourism, organs that can be manufactured in a lab and be ready for implant within a couple of hours, nanobots that repair damaged tissues and keep us young forever, the end of extreme poverty and hunger just to name a few. I predict that by 2020 life expectancy will increase by more than a year each year and it's all exponential from then on. Computation power doubles every year and we will reach the singularity soon. Many people laugh because they don't really understand, but all these great advances are coming a lot sooner than most people expect it! When all this is finally in place we will have peace.
