Answer:

Julia found 5 coins

Step-by-step explanation:

lets take the # of coins julia found as "x"

alice found6

davi found 5

lucas found 6

and carter found 8

remember how to calculate mean( add all numbers and divide by the# of numbers)

6+5+6+8+x/5=6 (since there are "5" terms)

25+x/5=6

treat this like a linear equation so multiply by 5 on both sides

25+x/5(5)=6(5)

25+x=30

subtract "25 on both sides"

25-25+x=30-25

x=5

hope this helps

Answer:

C. $\displaystyle \frac{cos(x)}{x} - ln(x)sin(x)$

General Formulas and Concepts:

Calculus

Differentiation

Derivatives
Derivative Notation

Derivative Rule [Product Rule]: $\displaystyle \frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)$

Trig Derivatives

Logarithmic Derivatives

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle f(x) = ln(x)cos(x)$

Step 2: Differentiate

Derivative Rule [Product Rule]: $\displaystyle f'(x) = \frac{d}{dx}[ln(x)]cos(x) + ln(x)\frac{d}{dx}[cos(x)]$
Logarithmic Derivative: $\displaystyle f'(x) = \frac{1}{x}cos(x) + ln(x)\frac{d}{dx}[cos(x)]$
Trig Derivative: $\displaystyle f'(x) = \frac{1}{x}cos(x) + ln(x)[-sin(x)]$
Simplify: $\displaystyle f'(x) = \frac{cos(x)}{x} - ln(x)sin(x)$
