Answer:
Domain is all real numbers. Range is [36- negative infinity]
Answer:
The imaginary part is the multiple of i. It is common practice to use the letter z to stand for a complex number and write z = a + bi where a is the real part and b is the imaginary part. where a is the real part and b is the imaginary part.
Step-by-step explanation:
You can easily check that a complex number z = x + yi times its conjugate x – yi is the square of its absolute value |z|2. Therefore, 1/z is the conjugate of z divided by the square of its absolute value |z|2.
Complex numbers A complex number z is defined as an ordered pair z = (x, y), where x and y are a pair of real numbers.
She worked 2 1/2 hrs yesterday and 4 1/4 hrs today...
2 1/2 + 4 1/4 =
2 + 4 = 6
1/2 + 1/4 = 2/4 + 1/4 = 3/4
so she worked a total of 6 3/4 hrs....or 6.75 hrs
she is paid $ 54
54 / 6.75 = $ 8 per hr <=== what she earned per hr
Answer:
p <= 19
Step-by-step explanation:
We have that the area of a sheet of paper is:
8.5 ft * 11 ft = 93.5 ft ^ 2
So the area of the bulletin board would come from:
1728 / 93.5 = 18.48 pieces of paper.
What it means is that the solution is a number greater than 18.48, an inequality this case represents would be:
p <= 19
Which means, as long as it's under 19, I could hang it up. It is approaching 19 because this type of situation approaches the largest number.
