Any complex number can be written in fallowing form:
Z = x + yi
When drawing complex numbers as point on x,y coordinate system we can use variables x and y to represent our coordinates in x y coordinate system.
Our complex number is:
Z = 3i which means
x = 0 and y = 3
x is real part of complex number and we draw it on x axis (real number axis) and y is imaginery part and we draw it on y axis (imaginery axis)
answer is point with coordinates (0,3) Graph 1
There are 16 cups in a gallon. Divide 100 into 16 to get 6.25. You now just multiply 3.12 by 6.25 to get 19.5. Your answer is $19.50.
hope this helps!
The area of a rectangle is calculated as length times its width. So, for the given area above, the expression should b written as:
20 = LW
To know the length for various measurement of the width, we can write it by:
L = 20 / W
You can substitute any measurement to W and you can obtain the corresponding value of the length.
1 3/4 - 5/6r = 8/3
-5/6r + 7/4 = 8/3
-5/6r +7/4 - 7/4 = 8/3 -7/4
-5/6r = 11/12
(6/-5)*(-5/6r)=(6/-5)*(11/12)
=-11/10
r = -1 1/10
