Is 70 the correct value for x?
Reptile [31]

Answer:

68 is what I'm getting for x

70 is the correct length of DH

Step-by-step explanation:

You can set up the proportion for this question.

99.2 / 62 = 112/(x + 2)   Cross multiply

99.2 ( x + 2) = 62 * 112   Combine the right side

99.2(x + 2) = 6944         Use the distributive principle to remove the brackets.

99.2*x + 2*99.2 = 6944 Combine the factors on the left

99.2x + 198.4 = 6944     Subtract 198.4 from both sides

99.2x = 6944  - 198.4     Combine the terms on the right

99.2x = 6745.6               Divide both sides by 99.2

x = 6745.6/99.2

x = 68

DH = 70

Patrick is an electrical engineer who is testing the voltage of a circuit given a certain current and resistance. He uses the fo
morpeh [17]

Based on the given current and the given resistance, the voltage of the current is 14 + j8

<h3>How to determine the voltage of the current?</h3>

From the question, we have the following parameters

current of 4+j2 amps and a resistance of 2-j3 ohms.

This can be rewritten as:

Current (I) = 4+j2 amps

Resistance (R) = 2-j3 ohms.

The formula to calculate voltage is given as

Voltage=(current) × (resistance)

Rewrite as:

V = I * R

Substitute the known values in the above equation

V = (4 + j2) * (2 - j3)

Expand the brackets

V = 8 - j4 + j12 + 6

Collect the like ters

V = 8 + 6 - j4 + j12

Evaluate the like term

V = 14 + j8

Based on the given current and the given resistance, the voltage of the current is 14 + j8
