• ### What is a good love song?

i care mostly about the lyrics doesn't have to sound perfect

• ### calculus question its pretty easy but I just don't see it?

f(-6)=30

f'(-6)=-5

f(30)=12

f'(30)=-4

g(12)=-25

g'(12)=-9

g(30)=-21

g'(30)=47

what is (g ∘ f)' (30)

what is (f ∘ f)' (-6)

• ### graph/easy calculus question?

f(x)= ca^x

it goes through the points (3,135) and (1,15)

please show the work to find it thanks

• ### how do i set up this calculus equation ? (beginner calculus)?

y=4x³-12x-21

find the equation of two tangent lines to the above function that go through the point (-2,3)

• ### easy calculus question.?

f(0) = 7

f'(0) = -5

g(0) = 6

g'(0) = -9

what is (f ∘ g)' (0) =

and what is (f+g)' (0) =

• ### easy probability question?

if you have a bag of 4 marbles (2 blue marbles, 1 red and 1green) and you can pick two marbles out of the bag was is the probability you will get a blue marble? a red? and a green?

• ### calculus limit question? it appears to be an easy question I'm just not seeing it?

find the limit as x goes to 3

x³ - 27

---------

(3-x)³

• ### calculus limit question, how does the absolute value effect the answer?

limit as x→1⁻ (from the left side if you can't see the little negative sign)

∣ 8x² - 5x - 3 ∣

---------------------

7x² - 10x + 3

factoring the top and bottom you can pull out at x-1 from the numerator and the denominator but I'm not sure how the absolute value effects the limit because when i solved it i got 11/4 when i checked it by substituting 0.99999 in for x I got the answer -11/4....please explain where my mistake is thanks a bunch

• ### calculus limit question involving absolute value.?

lim as x→3⁻⁻

∣ 11x² - 32x -3 ∣

-----------------------

7x² -23x +6

(the entire numerator is an absolute value if you can't see the lines in this font) it is a left handed limit as well ( x is not going to negative three its going to positive three from the left side)

• ### beginner calculus question...?

object moves with velocity(m/s) ... v= 6t - 3t^2

a) how far is the object after 2 seconds?

b) at 3 seconds the object is back where it started how far did it move?

i took the antiderivative and got 3t^2 - t^3 and found a) to be 4m but how do u do b)

• ### really easy calculus question?

i know 1/x is the derivative of lnx so does that mean that 2x/x^2 is the derivative of lnx^2...using the chain rule?

• ### find y' if e^xy = 2x + y?

more steps u show the better thanks

• ### trig identity question.... (1-sin2x) / cos2x = cos2x / (1+sin2x)?

prove this is true using identities... would be a big help thanks in advance

some names of programs to play the movie and where to get them would be great this is the torrent if that helps

• ### University programs... what is the next best thing to mechanical engineer?

live in alberta the u of c and u of a both offer a mechanical engineering course that i would like to take but not sure i will be able to meet requirement planning on getting a job in the oil patch considering Sait's 2 year petroleum engineer course

• ### Tire size question 35inch tire by 10inch width?

what is the tire code for 35inch tire with a 10inch width R16? .... example 245/70 R16

• ### First date ideas plz?

want to do dinner and movie but there isn't much playing in theaters that i would go see
