Answer:
f(2) = -6
General Formulas and Concepts:
Order of Operations: BPEMDAS
Substitution and Evaluation
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -2x² + 4x - 6
f(2) is x = 2
<u>Step 2: Solve</u>
- Substitute: f(2) = -2(2)² + 4(2) - 6
- Exponents: f(2) = -2(4) + 4(2) - 6
- Multiply: f(2) = -8 + 8 - 6
- Add: f(2) = -6
In one full rotation/revolution, a point on the edge travels a distance equal to the circumference of the gyroscope, or 2<em>π</em> (18 cm) = 36<em>π</em> cm. Convert the angular speed, 36<em>π</em> cm/rev, to linear speed:
(36<em>π</em> cm/rev) • (35 rev/min) = 1260<em>π</em> cm/min ≈ 3958 cm/min
The major advantage of exponential notation is that it simplifies a number into a more readable form, so we don't have to count all the zeros every time we look at it / calculate it. It helps us to identify big numbers as small decimals which we are more familiar with.
