G evaluate lim h → 0 (1 + h)9 − 1 h . hint: this limit represents the derivative of a function f at a given point

Bond [772]

$\displaystyle\lim_{h\to0}\frac{(1+h)^9-1}h$

Write $1=1^9$ , and recall that for a differentiable function $f(x)$ , the derivative at a point $x=a$ is given by

$f'(a)=\displaystyle\lim_{h\to0}\frac{f(a+h)-f(a)}h$

which would suggest that for this limit, $f(x)=x^9$ and $a=1$ . We have $f'(x)=9x^8$ , and so the value of the limit would be $9(1)^8=9$ .

The volume of a rectangular solid can be written as V=LWH, where L is the length of the solid, W is the width, and H is the heig

marshall27 [118]

Answer:

The length of the rectangle is 9 inches.

The height of the rectangle is 11 inches.

Step-by-step explanation:

Given : The volume of a rectangular solid can be written as V=LWH, where L is the length of the solid, W is the width, and H is the height. A box of cereal has a width of 2 inches. It’s height is 2 inches longer than it’s length. If the volume of the box is 198 cubic inches.

To find : What are the length and height of the box ?

Solution :

The width of the box is L inches

The width of the box is W=2 inches

The height is 2 inches longer than it’s length i.e H=L+2

The volume of a rectangular solid is $V=L\times W\times H$
