kap26 [50]

Answer:

40 problems in 100 minutes

Step-by-step explanation:

This is a ratio problem.

You first divide 30 minutes by three to get how many problems she can do in 10 minutes. What you do to one side you do to the other side. So then, you should have 4 problems in 10 minute. Then, you multiply 10 by 10 and 4 by 10 to get 40 problems in 100 minutes.

Find the derivative using the limit process of f (x) = - 10x

zubka84 [21]

Answer:

$\frac{d}{dx} f(x) =-10$

General Formulas and Concepts:

Calculus

Derivative Notation
Definition of a Derivative: $\lim_{h \to 0} \frac{f(x+h)-f(x)}{h}$

Step-by-step explanation:

Step 1: Define

f(x) = -10x

Step 2: Find Derivative

Substitute: $\frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10(x + h)-(-10x)}{h}$
Distribute -10: $\frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10x -10h-(-10x)}{h}$
Distribute -1: $\frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10x -10h+10x}{h}$
Combine like terms: $\frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10h}{h}$
Divide: $\frac{d}{dx} f(x)= \lim_{h \to 0} -10$
Evaluate: $\frac{d}{dx} f(x)=-10$

An old adage states that "You can't fit a square peg in a round hole." Actually, you can, it just won't fill the hole. If a hole

VLD [36.1K]

Suppose the peg is like a rectangular prism:

It will be a right triangle with two sides of 2 and 2 because the diameter is 4.
c=√(2²+2²)
c=2√2
so the width of the largest peg is 2√2 or 2.83 inch
