Answer:

Max E=3.8 Voltage

Step-by-step explanation:

maximum-value -of cos(\theta) =1, when \theta=0,360,720\\110\pi t=0, therefore t=0, 1.04, 2.08 etc

The volume of a sphere is 3,000π m3. What is the surface area of the sphere to the nearest square meter?
kolezko [41]
First, solve for the radius of the sphere using the volume and the equation,
                                  V = 4πr³ / 3
Substituting for the known values,
                       3000π m³ = 4πr³/3
The value of r from the equation is approximately 13.10 meters. The equation for the surface area is,
                             SA = 4πr²
Substituting the value of radius,
                             SA = 4π(13.10 m)² = 2157.74 m²
Therefore, the surface area is approximately 2157.74 m².

Write two sets of 5 different numbers that have the same mean but different standard deviations
Zina [86]

Answer:

The sets could be 5, 5, 5, 5, 5 and 0, 10, 20, -10, 5

Step-by-step explanation:

Standard deviations are a measure of how far the average point is away from the mean. In the first example, each term is exactly the mean. In the second set, some are quite a distance from the mean and therefore, it would have a bigger standard deviation.
