Answer:

the answers are d and b

Step-by-step explanation:

d. 19x - 18 = -19x + 18

38x - 18 = 18

38x = 36

x= 36/38= 18/19

b. 19x + 18= -19x + 18

38x + 18 = 18

38x = 0

x =0

Answer:

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

General Formulas and Concepts:

<u>Calculus</u>

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:

<u>Step 1: Define</u>

<em>Identify</em>

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

<u>Step 2: Differentiate</u>

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

4. What percent relates to when an event will definitely happen?
Pavel [41]

Answer:

C

Step-by-step explanation:

If we know that the event will <em>definitely</em> happen, then there is no doubt and no probability that the event will <em>not</em> happen.

This means that the probability is 1, which is the same as 100%.

Find the midpoint of A(5,3) and B(3,-5). Place your answer in (x,y) notation with no spaces.
kifflom [539]
Midpoint means 1/2 way 
separate the x's and the y's find the middle of the x length, middle of the y length 
 x: 5 - 3 = 2    1/2 of 2 = 1   from either end  (3 + 1) or (5-1) = 4 
y: 3-(-5) = 8     1/2 of 8 = 4   from either end  (3-4) or (-5 +4) = -1 

midpoint is therefore (4, -1)
