How can you make your answer (41-13i)/(25) into a+bi form?

KengaRu [80]

Hello, do you know that for any a, b and c real numbers with c different from 0 the following is correct?

$\dfrac{a+b}{c}=\dfrac{a}{c}+\dfrac{b}{c}$

Then,

$\dfrac{41-13i}{25}=\dfrac{41}{25}-\dfrac{13}{25}i$

So,

$a=\dfrac{41}{25}\\\\b=\dfrac{-13}{25}$

Thank you.

Answer:

3.32ft

Step-by-step explanation:

The wire and the poles attached to the ground form a right triangle with the length of the wire being the hypotenuse.

Using Pythagoras Theorem:

Hypotenuse²=Adjacent²+Opposite²

6²=5²+x²

x²=36-25

x²=11

x=√11=3.32 ft.

The wires are attached 3.32 ft from the base of the pole on the ground

What is the equation of a line with a slope of -1/2 and passes through the point (6,-6)

Vlad [161]

Well I am going to assume you need slope-intercept form. So the equation is y=mx+b. m is slope, b is y intercept. So you just plug it in -6= -1/2(6)+b. -6=-3+b. Now you figure out for b so what does b have to be to make the equation equal. Well -3 so -6=-3+-3, or -6=-6.

y=-1/2x-3

Hope that helped
