Answer:

z1 + z2 = 3

Step-by-step explanation:

Since we are given z1 = 2 + √(3)i and z2 = 1 – √(3)i. The sum of z1 + z2 would be:

(2 + √(3)i) + (1 – √(3)i) = 2 + √(3)i + 1 – √(3)i = 2 + 1 + √(3)i – √(3)i = 3

Hence, z1 + z2 = 3.

What is the arc length of a semicircle with a radius of 14?

Deffense [45]

Answer:

Perimeter of the semicircle is the formula r(π+2).

Radius r=14 cm

So, perimeter =14(π+2)... where π= 22/7

=2(22+14)=44+28=72 cm

So , the answer is

72 I guess

Which of the following could be the graph of y = –xn where n is odd?

mina [271]

Answer:

Step-by-step explanation:

I think you meant y = -x^n, where ^ denotes exponentiation.

If n is odd, the graph begins in Quadrant II and decreases through the origin into Quadrant IV. This is true of -x, -x^3, -x^5, and so on.
