Use the algebraic procedure explained in section 8.9 in your book to find the derivative of f(x)=1/x. Use h for the small number

Triss [41]

Answer:

By definition, the derivative of f(x) is

$lim_{h\rightarrow 0}\frac{f(x+h)-f(x)}{h}$

Let's use the definition for $f(x)=\frac{1}{x}$

$lim_{h\rightarrow 0} \frac{\frac{1}{x+h}-\frac{1}{x}}{h}=\\lim_{h\rightarrow 0} \frac{\frac{x-(x+h)}{x(x+h)}}{h}=\\lim_{h\rightarrow 0} \frac{\frac{(-1)h}{x^2+xh}}{h}=\\lim_{h\rightarrow 0} \frac{(-1)h}{h(x^2+xh)}=\\lim_{h\rightarrow 0} \frac{-1}{x^2+xh)}=\frac{-1}{x^2+x*0}=\frac{-1}{x^2}$

Then, $f'(x)=\frac{-1}{x^2}$

Container A can hold 9 cups of liquid. container B can hold 5 pints of liquid. Container c can hold 2 quarts of liquid. Whice co

nata0808 [166]

Hello!

1 cup = 0.5 pints

1 cup = 0.25 quarts

That means that 9 cups are equivalent to 4.5 pints and 2.25 quarts of liquid.

1 pint = 2 cups

1 pint = 0.5 quarts

That means that 5 pints are equivalent to 10 cups and 2.5 quarts of liquid.

1 quart = 4 cups

1 quart = 2 pints

That means that 2 quarts are equivalent to 8 cups and 4 pints of liquid.

FINAL ANSWER:

Judging by our calculations, Container B has the greatest capacity.
