x^x

A. The functions have comparable growth rates

Is it x^x? I chose it because it begins to grow faster once x>50 but other than that I...errr help/explain please.

1 AnswerMathematics4 years ago### Please clear up my confusion if you can: "Examine the discriminant. For what value(s) of b is(are) there two imaginary roots?"?

The given information is:

"Show that the general quartic polynomial f(x) = x^4 +ax^3 +bx^2 +cx +d has either zero or two inflection points, and the latter case occurs provided that b < (3a^2)/8.

After googling and youtubing for a bit I still sorta don't know...what I don't even know. Teach me someone please.

1 AnswerMathematics4 years ago### finding the d/dx of xsqrt(49-x^2)?

so my thought process

f '(x) = d/dx xsqrt(49-x^2)

= (1)(sqrt(49-x^2)+(x)(1/2(sqrt(49-x^2)(-2x)

=sqrt(49-x^2) - (2x^2)/2(sqrt(49-x^2))

=sqrt(49-x^2) - x^2/ sqrt(49-x^2)

=(1-x^2)/sqrt(49-x^2)

......

my answer sheet says im wrong but idk where i messed up. pls help

4 AnswersMathematics4 years ago### Confused on continuity of a function?

If a<b and f(a) ≤ L ≤ f(b), then there is some value of c between a and for which f(c) = L

true || false

and also

Suppose f is continuous on [a,b]. Then there is a point c in (a,b) such that f(c) = [f(a) + f(b)] / 2

true || false

if you could explain why that would be awesome

2 AnswersMathematics5 years ago### any animes to watch in this genre?

Well it's not really a genre, however do you guys know any anime where the protagonist is suddenly taken into a new world or something along the lines of that? I really like the whole fantasy element too

Some things I've watched so far (kinda had mixed feelings about some thought =.=):

Marchen Awakens Romance

Zero no tsukaima

Dog Days

are there any more like these? they dont necessarily need to be all light hearted like these either

8 AnswersComics & Animation9 years ago### If i want to lose fat...?

When I exercise should I be doing short burst of high intensity workouts or one long continuous work out? For example, should I be doing sprints and weights and then sprints with little breaks/pauses in between or go for long runs instead? I've been told this works and that works and stuff but I'm not sure what to do? Recently I've been doing more short high intensity work outs but after like 5 minutes of going "pure all out" I get too exhausted to do anymore. What should I do? Also should if it is high intensity, then how many times a day should I do it? Length of time in between? Thanks!

1 AnswerVideo & Online Games9 years ago### Can somebody give me a work out routine?

I want to get fit, healthy, strong, all that good stuff and I'm willing to go through the pain of exercise and proper eating to get it done. BUT I'm not exactly sure what I should be doing so can anyone help me on what to do?

I'm 5 feet and 7 inches tall. Korean. Around 175lbs. 18 years old. I used to play football in high school (defensive line) so at the time I tried to stay big, but now that I'm going to college I really want to slim down.

Recently I've been eating just lettuce and chicken (breasts? i think) with no sauce or dressing. I've been trying to do more cardio but I hurt my leg at one point and had to stop for a month, I want to start back up again now that I'm almost 100% healed but I can't seem to force myself to work out without a routine to follow. (While I 'dieted' a month before my injury, I shed off around 10 pounds, but I see no visible difference so I'm worried I'm just losing muscle instead of fat.

PLEASE HELP ME GUYS: WHAT WORK OUTS, HOW LONG, WEEKLY, WHAT FOODS TO EAT, AND HOW MUCH TO EAT. -THANKS!
