Find the volume of the bag and candle.Round to the nearest tenth
user100 [1]
The volume of the bag will be found by multiplying the length times the width times the height. This would be 5.5 x 3 x 8. The volume of the bag is 20.9 cubic inches. The volume of the candle would be found by using the formula for finding volume of a cylinder. V =pi(approximately 3.14) x r^2 x h, where r is the radius( half the diameter) and h is the height. V = 3.14 x 1.25 x 1.25 x 6. The volume of the cylinder would be 29.4 cubic inches.

What is the product of complex conjugates? (1 point)
Leno4ka [110]

Answer:

A. the product of complex conjugates is a difference of two squares and is always a real number

Step-by-step explanation:

Given a complex number z1 = x+iy where x is the real part and y is the imaginary part.

The conjugate of a complex number is the negative form of the complex number z1 above i.e z2= x-iy (The conjugate is gotten by mere changing of the plus sign in between the terms to a minus sign.

Taking the product of the complex number and its conjugate will give;

z1z2 = (x+iy)(x-iy)

z1z2 = x(x) - ixy + ixy - i²y²

z1z2 = x² - i²y²

.since i² = -1

z1z2 = x²-(-1)y²

z1z2 = x²+y²

The product gave a real function x²+y² since there is no presence of complex number 'i'

It can also be seen that the product of the complex numbers z1z2 is like taking the difference of two square. An example of difference of two square is that of two values a and b which is (a+b)(a-b).

From the above solution, it can be concluded that the product of complex conjugates is a difference of two squares and is always a real number.
