The relationship between voltage, E, current, I, and resistance, Z, is given by the equation E = IZ. If a circuit has a current

I = 3 + 2i and a resistance Z = 2 – i, what is the voltage of the circuit?

I=3+2i
Z=2-i
i=√-1
i²=-1
E=IZ=(3+2i)(2-i)=6-3i+4i-2i²=6+i-2(-1)=6+i+2=8+i.

Solution: E=8+i

Find the maximum rate of change of f(x; y) = 4y p x at the point (4,1) and the direction in which it occur
olga2289 [7]

Answer:

16p

Direction: positive/upward direction

Step-by-step explanation:

First, the function is f(x,y) = 4ypx

At the point where x=4 and y=1, the maximum rate of change of the function f(x,y) is

4(1)p(4) = 16p

The direction in which it occurs is the positive(upward) direction

Find the volume of the cone round your answer to the nearest tenth
Ainat [17]

Answer:

209.43951 round to the nearest tenth is 209.44

Step-by-step explanation:

A cone with a base radius of 5 units and a height of 8 units has a volume of 209.44 cubed units.

If a cone has a flat bottom, meaning the height and radius meet at right angles, then this formula can be used to find of volume ('V') of that cone (also know as a right circular cone):

V = 1/3(PI*r squared * h )

The volume of a cone can be calculated by taking one-third of the result of the radius squared, multiplied by the height, multiplied by the mathematical constant pi.

Here is a step-by-step case that illustrates how to find to volume of a cone with a radius of 2 feet and a height of 3 feet. Note that in order to save space (and because pi cannot be determine precisely) a limited number of decimal places are used, the symbol ~ denotes that this answer is an approximation.

V = 1/3(pi * r^2 * h)

= 1/3(pi * 2^2 * 3)

= 1/3(pi * 12)

= 1/3(37.7)

~ 12.6 cubic feet

Hope this helps!!
