<u><em>Answer: -2/5+1/5i</em></u>
Explanation:
complex rule.
(-3*7+1*1)+(1*7-(-3)*1)i/7²+1² ← as the fractions
then refine and rewrite the problem down.
-20+10i/50 ← as the fractions shown.
-20+10i/50=-2+i/5
you can also rewrite the problem down in standard complex form.
-2+i/5=-2/5+1/5i
<u><em>=-2/5+1/5i</em></u>
Hope this helps!
Thanks!
Have a great day!
Answer:
100mm
Step-by-step explanation:
Multiply the length times the width
Answer:
The sum is x^2 + x, the product is x^3.
Step-by-step explanation:
Adding x^2 and x leaves no like terms, so no simplification is required.
Multiplying gives x^2*x, which is x*x*x, which is then x^3
Answer:
n = 6 is closest to the correct value.
Step-by-step explanation:
For the terminal side to fall on the y-axis, the angle must be a multiple of 90 degrees. Setting (525n)° = (90)°, or n = 525/90 = 5 5/6.
The answer n = 6 is closest to this result.
Answer:
angle 7= 66
Step-by-step explanation:
Angle 1 is equal to the 114 degrees. And angle 1 + angle 7 = 180. So it would be 114 + angle 7 = 180. So you do 180-114 = 66. So angle 7= 66.
The other way is that 114 + angle 6 = 180, so you do 180-114= 66.
And agle 6 is equal to angle 7, so that's another way you can know that angle 7= 66
