<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:
f(x)=x^2+1 -> f(a+1)=(a+1)^2+1=a^2+2a+1+1=a^2+2a+2
Step-by-step explanation:
Change the problem statements into equations or inequalities as appropriate.
"<span>The perimeter of a rectangle is at most 200 feet. The length of the rectangle is five less than four times the width. What are the maximum dimensions of the rectangle?"
P = Perimeter (is less than or equal to) 200 feet)
length = 4(width) - 5
Your job is to figure out the maximum length and the width of this rectangle.
If </span>P = Perimeter (is less than or equal to) 200 feet), then this is a constraint on the length and width of the rectangle.
2(length) + 2(width) (is less than or equal to) 200 feet)
2(4(width) - 5) + 2(width) (is less than or equal to) 200 feet
Let the variable "w" represent the width. Divide both sides of this inequality by 2. Simplify, to obtain an inequality for w.
