Which of these represents the conjugate of the impedance of a circuit written as 7 – i ohms?

A
–7 – i ohms

B
–7 + i ohms

C
–7i ohms

D
7 + i ohms

Answers

Answer 1

For the expression 7 - i ohms, the conjugate will be 7 + i ohms (the sign was changed from negative to positive)

The impedance of the circuit is written in form of a complex number.

The standard representation of a complex number is expressed as a + ib where:

a is the real part

ib is the imaginary part

The conjugate of the complex number a + ib will be a - ib. Note that the signs of the expression were changed from addition to subtraction.

Similarly for the expression 7 - i ohms, the conjugate will be 7 + iohms (the sign was chaged from negative to positive)

What is the midpoint of the line segment whose
endpoints (7,-4) and (-3, -2)?
are

Answers

Answer: (2, -3)

Step-by-step explanation:

To find the the answer, you will need to use the midpoint formula, which is as following:

(x₁+x₂/2, y₁+y₂/2)

Since we have two coordinates, let's substitute them into the equation.

(7 + (-3 )/ 2, (-4) + (-2)/2)

We should first add 7 and -3 together, as well as -4 and -2.

(4/2, -6/2)

We then divide 4 and -6 by 2. This would give us our midpoint coordinate.

Answers

Answer:

The area is 49/12 or 4 1/12

Step-by-step explanation:

The area of a triangle is:

a = 1/2 × base × height

a = 1/2 × 3 1/2 × 2 1/3 (4 2/3 is not the height!)

a = 1/2 x 7/2 x 7/3 (I converted all the fractions into improper fractions)

a = 49/12 (1 × 7 × 7 = 49, 2 × 2 × 3 = 12)

You can convert it back to a mixed number:

49/12 = 4 1/12
