(a) What is the capacity of the container?
Volume = length * width * height
V = 4ft * 2ft * 3ft
V = 24 ft³

(b) How much material was used to make the container?
Surface area = sum of 6 faces of the prism
4 ft x 3 ft = 12 ft² → 12 ft² x 2 = 24 ft²
4 ft x 2 ft = 8 ft² → 8 ft² x 2 = 16 ft²
2 ft x 3 ft = 6 ft² → 6 ft² x 2 = 12 ft²

Surface area = 24 ft² + 16 ft² + 12 ft² = 52 ft²

Find the first derivative of x^2+y^2=25

lozanna [386]

Answer:

$\frac{dy}{dx}=-\frac{x}{y}$

Step-by-step explanation:

Use implicit differentiation:

$x^2+y^2=25\\\\2x+2y\frac{dy}{dx}=0\\ \\2y\frac{dy}{dx}=-2x\\ \\\frac{dy}{dx}=-\frac{x}{y}$

Remember to treat "y" as a constant in implicit differentiation and include dy/dx.
