Finding a Derivative Using the Definition of a Derivative

y=(1/3x^3) - (5x) - (4/x) Dont use the shortcut method.-By (1/3x³), do you mean (1/3) x³ or 1/(3x³)? Ill assume the latter. f(x) = 1/(3x³) - 5x - 4/x f(x) = lim[h→0] (f(x+h) - f(x)) / h . . . = lim

What kind of triangle has 4 right angles

My teacher was showing us how to draw a triangle with 4 right angles, everyone drew theirs and we even counts the angles, everyone understood what was happening except me.. could someone please explai

How to find the derivative of a function

8 sqrt(8^x+6) The first 8 is not in front but on the square root symbol. I dont know how to answer these kind of problems. help-You use the chain rule, and the power rule. Answer in prettyprint availa

MATH problem, is this right

Given g(x)= x^2+12x find a g(3) b(g-5) and C(0) (3)^2+12(3)= 9+36=45 now for b- (-5)^2+12(-5) 25+(-60)=-35 and I know the next one is zero when I replace all the xs with 0. So did I do this right?

Help with composite function and absolute value please

How do I find f(g(x)) if f(x) = sq root all of x-5.. and g(x) equals absolute value of all of 4-x^2. The answer is suppose to be sqrt x^2-9-g(x)=|4-x^2| and f(x)=sqrt(x-5) f(g(x)= =f(|4-x^2|) = sqrt(|

Find the equation of the tangent line to y=lnx at x=1

I got the equation and its x-1, but I dont know how to answer the second problem. Use it to calculate approximate values forln(1.2) and ln(2.5). How do I calculate the approximate values?.-y(x) = ln(x

Help w/ projectiles??!!(the last one on my hw that i cant solve!!!!)

An arrow is shot at an angle of 33º above the horizontal with a velocity of 26.5 m/s. When the arrow lands back on the ground, how far did it travel horizontally? Round your answer to 2 decimal places

Determine the point at which the graph of the function has a horizontal tangent line.

i need to Determine the point at which the graph of the function has a horizontal tangent line in this: f(x)=3x^2/x^2+7........i apparently need a (x,y) value. but i cant figure it out no matter what

Calculus 3 limit problem, help please

find the limit of the function, if it exists as x and y approach zero[y^2sin^2(x)]/[x^4+y^4] [xy]/[x^2+y^2]^(1/2) Much appreciated!-1) Try different paths to the origin. x = 0 ==> lim(y→0) 0/x^4 =

Math help please :]!!!!!!!!!!!!!!

Write the equation of the line which passes through (5, –2) and is parallel to x = 4. (1 point) if you know it please help me :P-line equetion in general is y = mx + b x =5 , Y = -2 -2 = m * 5 + b

Help with math function problem

Given f(x)=x^2+2x-3, find f^-1(x). If u didnt know f^-1 is basically the inverse of f(x)-y = x^2 + 2*x - 3 x = y^2 + 2*y - 3 y^2 + 2*y = x + 3 y^2 + 2*y - (x + 3) = 0 a = 1, b = 2, c =- ( x + 3)

I need help Solving for x and finding the zeros of f(x) (please help me)

Solving for xx^2 -3x = - 2 Find the zeros of f (x) =- 4(x-1)^2 + 4-x^2 - 3x = -2 Moving all values to the left side: x^2 - 3x + 2 = 0 Factor: (x - 2) * (x - 1) = 0 Solving, you get x = 1 and x =
