I don't get how to do this and I'm not sure how to use the ln y' =

How do I solve it?

so I am asked to maximize l*w*h = 2w^2*h l*w +2w*h+2lh=600 I solved for h in terms of w 2w*w+2wh+2*2wh=600 2wh+4wh=600-2w^2 h(6w)=600-2w^2 h=(600-2w^2)/(6w) I...

It says to eliminate one variable so I eliminated x. A=xy L2=x2+y2 x=(L2-y2)1/2 A=y*(L2-y2)1/2 =(L2y2-y4)1/2 Derivative =1/2(L2y2-y4)-1/2...

What is the perimeter of the rectangle? I don't know how to solve this question using optimization methods. How I solved it: sqrt1225 to find the smallest dimensions...

the particle is moving along the curve y=sqrtx. As the particle passes through the point(4,2) its x-coordinate increases at a rate of 3cm/s. How fast is the distance from the particle to the...

I drew a Lewis Structure of ClO3- with 3 double bonds instead of 2 and 1 single bond but I'm wondering if it is a valid structure. Is there a maximum amount of double bonds that Cl can make...

I am stuck can you please help? So far I have limx->9√x-√9 x -9 ...

Using chain rule and product/quotient rule, find derivative of sin(3x^2)/x when x=(squareroot of pi)

sin(3x^2)x^-1 this is how far I got. when do I sub in √pi ? what do I do next?

a)such scenario is not possible b)f(x) has a vertical tangent at x=0 c)f(x) must be discontinuous at x=0 d)f(x) has a vertical assymptote at x=0, and f(0) is defined to be 0. I...

a)instantaneous rate of change of f at a b) difference quotient of f at a c)definition of f'(a) d)secant line of f at a I tried a) and c) but they're wrong. What...
