Answer:
thats easy you don't need help
Step-by-step explanation:
The answer to your question is " D.)119"
Simplifying the square of a complex binomial is done similarly to a purely real binomial, except that one was to remember the relation i² = -1.
Solving the equation (8 – 5i)<span>² is done below:
Rewriting </span>(8 – 5i)<span>²:
(8 - 5i)(8 - 5i) = 64 - 40i - 40i + 25i</span><span>²
Simplifying and applying </span><span>i² = -1</span><span>:
64 - 80i + 25(-1)
64 - 80i - 25
39 - 80i
From the choices, the answer is C. </span>
Answer:
292.45 m
Step-by-step explanation:
Both disk are at an angle of 38.48°
From the image below we calculate as,
For disk B, direct distance is 1.296 km from receiver = 1296 m
Vertical height from ground will be = 1296 x sin38.48 = 806.42 m
For disk A, direct distance is 826 m from receiver
Verival height above ground = 826 x sin38.48 = 513.97 m
Difference in height between disks is 806.42 - 513.97 = 292.45 m
Answer:
45%
Step-by-step explanation:
40 * .45 = 18
40-18 = 22
