What is the value of i^20+1?
ICE Princess25 [194]

You know

i^2=-1

Squaring both sides gives

(i^2)^2=(-1)^2\implies i^4=1

Then raising both sides to any integer power n gives

(i^4)^n=1^n\implies i^{4n}=1

That is, any power of i where the power is a multiple of 4 will always be equal to 1.

So

i^{20}+1=1+1=2

But perhaps you mean to write 20+1 as the exponent, in which case

i^{20+1}=i^{20}i=i

What is the slope-intercept form of the equation of the line containing the points (−2, 4) and (6, 0)?
Nikolay [14]

The slope-intercept form of the equation of the line containing the points (−2, 4) and (6, 0) will be y =0.5 x+ 5.

<h3>What is the slope?</h3>

A numerical assessment of a line's angle relative to the ground is known as the slope.

The inclination of any line, ray, or line segment is the fraction of the perpendicular to the horizontal distance between any two positions on it.

The slope of the line is found as;

\rm m = \frac{y_2-y_1}{x_2-x_1} \\\\ m = \frac{0-4}{6-(-2)} \\\\ m = \frac{-4}{8} \\\\ m = \frac{-1}{2}

The standard line equation is;

y-y₁=m(x-x₁)

\rm y-4= \frac{-1}{2}(x-(-2)) \\\\ 2y-8 = x+2 \\\\ 2y =x+10 \\\\ y = 0.5 x + 5

Hence, the slope-intercept form of the equation of the line containing the points (−2, 4) and (6, 0) will be y =0.5 x+ 5.
