The complex number is
-3i
There is no real number
a = 0
b = -3
The value of r is
√(0² + (-3)²) = 3

The trigonometric form of the comoplex number is
y = 3 cos θ
and 
x = 0

In a triangle the measure of the first angle is twice the measure of the second angle. the measure of the third angle is 8 degre
Rufina [12.5K]
Let's call the missing angles Q, R, and S. We know that Q = 2R and S = R - 8 and we also know that Q + R + S = 180. So that really just means that              180 = 4R - 8  Add 8 on both sides of the equal sign
188 = 4R So we divide on both sides of the equal sign by 4
47 = R And that means that Q = 2 * 47 So Q = 94 and S = 47 - 8 So S = 39
39 + 94 + 47 = 180
The missing angles are 39 degrees 94 degrees and 47 degrees.

Find the equation of the line that has a slope of 3 and passes through (-1, 2)
Nadusha1986 [10]

Answer:

y= 3x+5

Step-by-step explanation:

start with the linear equation formula

y= mx+b

indentify what you already have.

x= -1 and y= 2 and m(slope)= 3

We are solving for b, so plug in what you have.

2= 3(-1)+b

Simplify.

2= -3+b

Add 3 on both sides.

5= b

Rewrite your equation with the x and y values.

y= 3x+5

Ben is 12 years older than Ishaan. Ben and Ishaan first met two years ago. Three years ago, Ben was 4 times as old as Ishaan.
bixtya [17]
So, the 2 equations would be.... B -12 = I   and    (B - 3) = 4(I - 3)  the second sentence is irrelevant.
B - 3 = 4 (I) - 12
B - 3 = 4B - 48 - 12
B - 4B = -60 + 3
-3B = -57
B (Ben) = 19
Ishaan is 7

Hope this helps!
