Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point A(2, 125)

Point B(98, 15)

Step 2: Identify

A(2, 125) → x₁ = 2, y₁ = 125

B(98, 15) → x₂ = 98, y₂ = 15

Step 3: Find distance d

Substitute in coordinates [Distance Formula]: $\displaystyle d = \sqrt{(98-2)^2+(15-125)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(96)^2+(-110)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{9216+12100}$
[√Radical] Add: $\displaystyle d = \sqrt{21316}$
[√Radical] Evaluate: $\displaystyle d = 146$

Which one of the following statements is true? (5 points)

DanielleElmas [232]

Answer:

None of these statements are true.

Step-by-step explanation:

a) The derivative of (fg)(x) is f'g +fg' according to the product rule for derivatives.

b) The derivative of |x² +x| is a 3-part piecewise linear function equal to 2x+1 for |x+1/2| > 1/2, and equal to -2x-1 for |x+1/2| < 1/2. It is undefined for x=0 and x=1.

c) for y = √f(x), y' = f'(x)/(2√f(x))
