We are integrating f(x) = 9cos(9x) + 3x²: 
a) Apply the sum rule

b) Calculate each antiderivative
<u>First integral</u>

1. Take out the constant

2. Apply u-substitution, where u is 9x

3. Take out the constant (again)

4. Take the common integral of cos, which is sin

5. Substitute the original function back in for u and simplify
6. Always remember to add an arbitrary constant, C, at the end

<u>Second integral</u>

1. Take out the constant

2. Apply the power rule,
, where <em>a</em> is your exponent
⇒ 
3. Add the arbitrary constant

c) Add the integrals
sin(9x) + C + x³ + C = sin(9x) + x³ + C
Notice the two arbitrary constants. Since we do not know what either constant is, we can combine them into one arbitrary constant.

Answer:</h3>
F(x) = sin(9x) + x³ + C
Answer:
Step-by-step explanation:
<u>Slope-intercept form: </u>
<u>Use two of the ordered pairs and find the slope:</u>
- m = (1-2)/(0-(-2)) = -1/2
<u>y-intercept is 1 as point (0, 1) is given in the table:</u>
<u>The line is:</u>

Answer:
True
Step-by-step explanation:
If this is a true or false question it is true.
22 x 20% = 2.2
22 ÷ 10 = 2.2
