I need help please thank you
Dafna11 [192]

Answer:

See attachment

Step-by-step explanation:

We can graph this line using the equation given to us. The equation is in slope-intercept form, y=mx+b. In this form, m = slope and b = the y-intercept.

So, we can tell that the slope is -\frac{1}{5} and the y-intercept is (2,0).

We begin by plotting on the graph the y-intercept, (2,0).

The slope also equals the \frac{rise}{run}. The slope is negative, so the line will slope down. From the point we have plotted, we will <em>rise</em> negative 1 unit. This means to move down<em> </em>1 unit. From this point, we will <em>run</em> 5 units. Because the line is negative, we will move 5 units to the left, not the right. We land on point (5,1).

Now, we will draw a line from these two points. This is the line shown in the equation.

Good luck ^^

Given w = 1 + i, what is arg (w) and |w|? Explain how you got your answer.
kirill [66]

Answer:

arg (w)=π/4 and  |w|=√2

Step-by-step explanation:

If z= x+iy is a complex number, then |z| is given by √ ( x²+y² ).

And the argument (z) is given by Ф = tan⁻¹ ( y/x ) where -π < x < π.

Now, in our case w= 1+i i.e. x=1 and y=1.

Therefore, arg (w) = tan⁻¹ (1/1) = π/4 and |w|=√ ( 1²+1² ) = √2 (Answer)
