The real part of given complex number -3 + 9i is -3
<em><u>Solution:</u></em>
We have to find the real part of complex number -3 + 9i
A Complex Number is a combination of real Number and an imaginary Number
<em><u>The general form of complex number is:</u></em>
a + bi
Where "a" and "b" are real numbers and i is the unit imaginary number
The given complex number is:
-3 + 9i
On comparing the above complex number with general form of complex number we get,
Real part = -3
Thus real part of given complex number is -3
Answer:
Step-by-step explanation:
Area is + 111.6 square meters
Formula : A/ 3.14 / 2
111.6 / 3.14 = 35.54
35.54 is the radius so multiply by 2 to get diameter .
35.54 / 2 = 17.77
Hope that’s right:)
The answer is g because 40/4 is 10 and minus 5 is 5 so the answer is G
You find your slope with the equation
(y2-y1)/(x2-x1)
(-1-2)/ -4-1.5)
(-3)/(-5.5)
.54x is your slope
you then plug that into your equation.
y=mx+b
y=.54x+b
you substitute one of our coordinates.
(-4,-1)
-1=.54(-4)+b
-1=-3.45+b
+3.45
2.45=b
your equation is
y=.54x+2.45
standard form
y-.54x=2.45
Answer:$8.36
Step-by-step explanation:
Change % to decimal and multiply
15% =.15
55.73 x .15 = 8.3595
