Basic calculus limit question FML save me will rate quickly

lim y-->0(y-(4sqrt(y)) +3) / (y^2+1) how in the hell do i do this ive tried everything...conjugate factoring...i keep getting 0 please help me-you should use lhopitals rule. Which involves you takin

What is 0.5| x-0.14| + 0.32 = 0.71

thanks-.92 is correct :))

If two lines are coplanar, then they are (always, sometimes, never) perpendicular

Sometimes. Parallel lines, intersecting lines, and perpendicular lines are all coplanar, so coplanar lines are only sometimes perpendicular.

Solving quadratic equations by completing the square

Firstly, I just want to say I am NOT trying to cheat on homework or anything - this is one of many exercises in my textbook and I could easily copy from the answers if I wanted to, but I want to thoro

Help with multiplying radicals, cannot seem to understand it.

(√3+1)(5√3+1) and √5 ( 9√3 – 6√25)-Dont let the radical signs confuse you. The first problem is: √3*5√3 + √3*1 + 1*5√3 + 1*1. √3*5√3 = 5*3 = 15 (since √3*√3 = 3) √3 + 5√3 = 6√3 (you have 1 + 5 √3s).

Let y = tan(2x + 7) --- MATH HELP PLEASE---

A) Find the differential dy when x = 4 and dx = 0.2 B) Find the differential dy when x = 4 and dx = 0.4 THANK YOU!-y= tan(2x+7) diff. both side using formula dy/dx = sec^2(2x+7)*2 dx.................

Made mistake *** NEW Basic calculus limit question FML save me will rate quickly

im really sorry i made a mistake y approaches 1 for this question not zero like the previous one that i asked sorry everyone please answer this one lim y-->1 (y-(4sqrt(y)) +3) / (y^2+1) how in the

What's the derivative of 0,5ln(x³+4)

10 points for the best answer!-y = (1/2)ln(x³ + 4) use chain rule y = (1/2)*1/(x³ + 4) * 3x² y = 3x²/(2x³ + 8)-y = 1/2 * ln(x^3 + 4) Put the 1/2 on the outside and just focus on d/dx (ln(x^3 + 4)) B

Calculus: Chain Rule

Suppose the functions f(x) and g(t) are defined as follow: f(x) = 6x, x ≥ 0 2x^2, x g(t) = 3t; t ≤ 0 t2; t > 0 a. Show that (g o f)(x) will be given by: (g o f)(x) = 36x2, x ≥ 0 4x4, x I am so

How to factorise 4x²+20x+24

take out the greatest common factor (4) 4(x^2+5x+6) then factor 4(x+3)(x+2) and thats the answer-when you are factoring you need to receive two parts in parentheses (4x+8)(x+3) To check is use the r

How do you do this maths question fast in an exam

http://www4.boardofstudies.nsw.edu.au/te…-Well you see that there are two semi circles which mean that you divide the circumference by two. The formula is: Pi times diameter We will be rounding Pi

How to find the equation f(x), if given f(1)= 2, f(3)= 4, f(9) = 1, integral of f(x)dx from 1 to 3 = 4...

How would you find the equation of f(x) (or what might you just call this), if given f(1)= 2, f(3)= 4, f(9) = 1, integral of f(x)dx from 1 to 3 = 4, integral of f(x)dx from 1 to 9 = -2. The question

It's the right answer right

x^1/3 times x^1/4 equals x^5/12, is that right?-No! its suppose to bex^7/12 i.e x^(1/3 + 1/4) LCM = 12, 3 into 12 is 4 and 4 times 1 is 4 also 4 into 12 is 3 and 3 times 1 is 3, x^(4 + 3)/12 = x^7/12.

SIMPLE calculus limit question PLEASE answer I vote fast :)

i dont understand how this problem and i really should. limT-->0T /(square root(4+T)- square root(4-T)) how do you solve this damn thing! and also shouldnt lim T-->0(T^2)(3T) / ((T+2)^2 - (T-2)^2

Made ANOTHER FKING mistake *** NEW Basic calculus limit question FML save me will rate quickly? sorry philo

m really sorry i made a mistake i made another ******* mistake denominator is y squared -1 lim y-->1 (y-(4sqrt(y)) +3) / (y^2-1) thanks for your patience guys sorry its late and im going nuts-Ther
