Why does the expression i to the power 4n+2 is always equal to -1

Alexandra [31]

Answer:

See Below.

Step-by-step explanation:

We are given:

$i^{4n+2}$

Using exponent properties:

$=i^{4n}\cdot i^2$

Rewriting:

$=(i^4)^n\cdot i^2$

Since i⁴ = 1 and i² = -1:

$=(1)^n\cdot -1$

1 to any power is still 1:

$=1\cdot -1 = -1$

Given f(x)=x+3 what is the range, when the domain is {-1,3,5,7}?

Slope = -1

x-intercept = 3/-1 = -3.00000

f-intercept = 3/-1 = -3.00000

Slope = 0.667/2.000 = 0.333

x-intercept = 3/-1 = -3.00000

f-intercept = 3/3 = 1

Slope = 0.400/2.000 = 0.200

x-intercept = 3/-1 = -3.00000

f-intercept = 3/5 = 0.60000

Slope = 0.286/2.000 = 0.143

x-intercept = 3/-1 = -3.00000

f-intercept = 3/7 = 0.42857

irrational

Step-by-step explanation:

Since π is an irrational number, it would make 3π/9 an irrational number too since multiplying or dividing by pi makes the answer an irrational number.

Which of the following describes how to translate the graph y = |x| to obtain the graph of y = |x - 6|?. . . shift 6 units up. s

s2008m [1.1K]

Answer:

Shift 6 units right.

Step-by-step explanation:

Easiest way to answer this question is to plot the two graphs:

Let's plot these graphs and analyse each graph.

Lets take the graph of $y=|x|$ that is attached.

We can clearly see that graph intersects x axis at x=0 and then essentially looks like y=x is mirrored by the y axis.

Now when we look at the $y=|x-6|$ that is attached,

We can see that graph intersects x axis at x=6 and is a composite graph of $y=|x-6|$ and its mirrored graph by y=6.

We can clearly see that graph has moved 6 units to the right.
