Answer:

4) v=kx^2/y^3

2= k(4^2)/(3^3)

2 =k16/27

k = 2(27/16) = 27/8

v = (27/8)(3^2)/(2^3 = (27/8)(9/8) = 243/64

v = 243/64 when x=3 and y=2

Need help solving this differentiation problem please. Thank you.

DIA [1.3K]

First convert the terms to fractional exponents

u = t^2/3 - 3t^3/2

differentiating

u' = 2/3 t^ (2/3 - 1) - 3* 3/2 t^(3/2 - 1)

= 2/3 t ^(-1/3) - 9/2 t ^(1/2)

= 2 / (3∛t) - 9 √ t / 2 in radical form

The diameter of a cylindrical water tank is 12ft , and its height is 14ft . What is the volume of the tank?

Luda [366]

So the formula for finding the area of a cylinder is $2 \pi r^{2}+2 \pi rh$ . r=radius. If we put the numbers into the equation it is $2 \pi 6^{2}+2 \pi 6(14)$ We get 6 as the radius because half of 12 is 6. 6 squared is 36 and 6*14= 84. So our equation is now $2 \pi36+2 \pi84$ . 2*pi=6.28318530718 but let's round that to 6.283. So now our equation is much simpler 6.283(36)+6.283(84). Just multiply them. 226.188+527.772= 753.96 is your final answer.
