If a car travels 120 miles in 2 hours, what is its rate of speed expressed as a unit rate?

erastovalidia [21]

The speed is 60 miles per hour

Step-by-step explanation:

Speed is the distance covered per unit time.

The formula for speed is:

$Speed = \frac{distance}{time}\\$

Given

Distance = d = 120 miles

Time = t = 2 hours

Putting the values in the formula

$s = \frac{d}{t}\\=\frac{120}{2}\\= 60$

What is the value of i4?

natima [27]

Answer:

Step-by-step explanation:

You want to know the value of i^4.

<h3>Powers of i</h3>

The fourth power of i, √(-1), can be found the same way the value of any fourth power can be found: carry out the multiplication.

i^4 = i·i·i·i = -1·i·i = -i·i = -(-1) = 1

The fourth power of i is 1.

<em>Additional comment</em>

As you can see from the evaluation process, ...

i¹ = i

i² = -1 . . . . . definition of i

i³ = -i

i⁴ = 1

The sequence repeats for higher powers.
