Answer: The complex conjugate has a very special property. Consider what happens when we multiply a complex number by its complex conjugate. We find that the answer is a purely real number it has no imaginary part. This always happens when a complex number is multiplied by its conjugate the result is real number.
Real numbers can be positive or negative, and include the number zero. They are called real numbers because they are not imaginary, which is a different system of numbers
Step-by-step explanation: Every complex number has a complex conjugate. The complex conjugate of a + bi is a - bi. For example, the conjugate of 3 + 15i is 3 - 15i, and the conjugate of 5 - 6i is 5 + 6i.
Answer:
D
Step-by-step explanation:
Answer:
r ≈ 2.39 inches.
Step-by-step explanation:
I think your question is missed of key information of the height, allow me to add in and hope it will fit the original one.
<em>The cylinder shown has a lateral surface area of about 750 square inches. Which answer is closest to the measure of the cylinder's radius? Use 3.14 to approximate pi. the height being 50 inches.</em>
My answer:
Given that the lateral surface area of about 750 square inches and its height is 50 inches.
We have the formula ti find the surface area of the cylinder is:
S = h(2πr)
<=> 750 = 50*2*3.14*r
<=> r ≈ 2.39 inches.
Hope it will find you well.
$7.50 + $6.25x = $26.25 would be a valid equation that can be used to determine the number of rounds he can play.
