When the height of liquid in a tub is x meters, the volume of liquid is Vm3, where
V = 0.05[(3x + 2)^3 - 8]
a) find an expression for dv/dx

If the liquid enters at a constant rate of 0.081m^3s^-1

b)Find the rate at which the height of the liquid is increasing when v = 0.95

since nobody want to post up question we go start easy

2x^4 + 34x^3 + 6

differentiate this blogbakes

tweety said...

y = 2x^4 + 34x^3 +6
dy/dx = 8x^3 + 102x^2

hey coke baby can u answer your question because to be honest with u if u start i wud maybe get an idea how to do it.
I think that one is a challenging one

DOH TAKE IT D WRONG WAY BUT IT WASNT MEANT TO BAD

moose you is the real bake

Le me give you one

4x/5^2 + 45/6^5 +54

Dante' said...

well, for the first question posted: dv/dx would be
:dv/dx = 0.05[9(3x + 2)^2]
right?

Prove that the function of y = x^3 , where x=a is 3a^2

lilo said...

What is the gradient of the curve y=√x+2 at x=16

lilo said...

Differentiate 7√x^3

everybody!!!
we get a question for mocks and i was abit confused. a little help here!!

Oil moves thru a pipeline such dat the distance 's'it moves and the time 't' are related by
s^3-t^2 = 7t. find the velocity of the oil for s = 4.01m and t = 5.25s

MOoSe said...

ok cruiser

4x/5^2 + 45/6^5 + 54

dy/dx = 4/25

voila!!!

cruiser you sure this is the question u want me to solve it looking kinda funny check it over na

MOoSe said...

ok tweety next one

3/2x^1/2 + 23x^2/3 + x^-3/4

take a crack at this na
