Answer:
(1 + 8i) / 65.
Step-by-step explanation:
When we divide by a complex number we multiply top and bottom of the fraction by the conjugate; this creates a real denominator.
So i / (8 + i) The conjugate of 8 + i is 8 - i, so we have:
i(8 - i) / (8 + i)(8 - i)
= (8i - i^2) / (64 - i^2) Now i^2 = -1 so we have:
(8i + 1) / (64 + 1)
= (1 + 8i) / 65.
Answer:
(500π)÷3
Step-by-step explanation:
area=4πr^2 , volume=4(πr^3)÷3
area=100π ,so r=5
B and D by simplifying the fraction
Is that the question is there any parts to it I mean I guess it’s a plot
Answer:
B for the first one , and C for the second
Step-by-step explanation:
for the first question DEG which is 60, and GEF which is 120, would equal to 180 degrees, which would be DEF because its a linear pair.
For the second question the are alternate exterior angles, so the are opposite of each other and on the outside.
