Answer:
B
Step-by-step explanation:
The formula for the area of a triangle is given as:
A = ½*base*height
A = ½*b*h
A = (bh)2
If we know the area (A) and the base, to find the height, the following would be done:
Divide both sides by b
A/b = h/2
Multiply both sides by 2
As we can see here, to find the base, we would divide the area by the vase, then multiply what we get by 2.
Answer:
Stationary Points: See below.
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Calculus</u>
Derivative Notation dy/dx
Derivative of a Constant equals 0.
Stationary Points are where the derivative is equal to 0.
Basic Power Rule:
Quotient Rule:
Step-by-step explanation:
<u>Step 1: Define</u>
<u>Step 2: Find 1st Derivative (dy/dx)</u>
<u>Step 3: 1st Derivative Test</u>
Our Critical Points (stationary points for rel max/min) are -2 and 2.
<u>Step 4: Find 2nd Derivative (d²y/dx²)</u>
<u>Step 5: 2nd Derivative Test</u>
Our Possible Point of Inflection (stationary points for concavity) is 0.
<u>Step 6: Find coordinates</u>
<em>Plug in the C.N and P.P.I into f(x) to find coordinate points.</em>
x = -2
x = 2
x = 0
<u>Step 7: Identify Behavior</u>
<em>See Attachment.</em>
Point (-2, -8) is a relative max because f'(x) changes signs from + to -.
Point (2, 8) is a relative min because f'(x) changes signs from - to +.
When x = 0, there is a concavity change because f"(x) changes signs from - to +.
