Recall that the imaginary number i has the definition of [tex]i = \sqrt{-1}[/tex]

List out the first few powers of i

I'm skipping steps when I listed out those terms, so let me know if you need to see them.

The process repeats every 4 items. This means we'll divide the exponent by 4 to look at the remainder.

Let's do that for the first exponent

12/4 = 3 remainder 0

The remainder 0 tells us that i^12 = i^0 = 1

Also,

22/4 = 5 remainder 2

The remainder 2 means i^22 = i^2 = -1

-------------------

In short:  i^12  = 1 and i^22 = -1

which means 6i^12 + 7i^22 = 6(1) + 7(-1) = -1

Answer: yes only if the number is negative itself.

Answer:

15x = 15x

or

0 = 0

Step-by-step explanation:

21(x + 1) - 6x = 15x + 21

21x + 21 -6x = 15x + 21

21x - 6x = 15x

15x = 15x

or

0 = 0

this equation is always true

Answer:

Step-by-step explanation:

Step 1: Convert
8 3/7= 43/5
7 2/15= 10/15

Step 2: Multiply
43×107=4601
----------
5×15=75

[tex]\frac{4601}{75}[/tex]

Step 3: Convert to an improper fraction

[tex]\frac{4601}{15}= 61\frac{26}{75}[/tex]

Hence, our answer is 61 26/75

The amount of money Nancy has is $12.5.

Given that, Steve has $5. Nancy has 250% as much money as Steve.

We need to find out how much money Nancy has.

A specific portion or amount in every hundred is what is meant by the term percentage. It is a fraction with the denominator 100, and the symbol for it is "%."

Let the amount of money Nancy has to be x.

Now, x=250% of 5

=250/100 × 5

=2.5 × 5

=12.5

The equation of this linear equation is f(x) = 9/7(x - 1) + 2

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

The given parameters are

f(−6) = −7, f(1) = 2

Start by calculating the slope (m) using

m = [f(-6) -f(1)]/[-6 - 1]

This gives

m = [-7 - 2]/[-6 - 1]

Evaluate

m = 9/7

The linear equation is then calculated as

f(x) = m(x - x1) + f(1)

So, we have

f(x) = 9/7(x - 1) + 2

Hence, the equation of this linear equation is f(x) = 9/7(x - 1) + 2

Based on the fact that the shape of the given square is dilated with a scale factor, the result would be the first square with a dimension of 3.

The Dilation is to be with a scale factor of 1/3.

This means that the dimensions on the new shape will be:

= Dimensions on original shape x scale factor

= 9 x 1/3

Answer:

Step-by-step explanation:

5x10^-7 is 0.0000005, while 8.5x10^-4 is 0.00085

0.00085/0.0000005=1700

Thus5 x [tex]10^{-7}[/tex] is 1700 times smaller than  8.5 x [tex]10^{-4}[/tex].

Option C is the correct answer.

Given,

5 x [tex]10^{-7}[/tex] and 8.5 x [tex]10^{-4}[/tex]

We need to find how many times smaller is 5 x [tex]10^{-7}[/tex] than 8.5 x [tex]10^{-4}[/tex].

Exponents are the power of a given number.

Example: a²

a - base

2 - exponent

Compare 5 x [tex]10^{-7}[/tex] and 8.5 x [tex]10^{-4}[/tex].

5 x [tex]10^{-7}[/tex]  can be written as 5 / 10000000

8.5 x [tex]10^{-4}[/tex] can be written as 8.5 / 10000

Now,

5 / 10000000 = 0.0000005

8.5 / 10000 = 85 / 100000 = 0.00085

We see that,

0.0000005 is less than 0.00085

Now,

0.0000005 x 1700 = 0.00085

5 x [tex]10^{-7}[/tex] is 1700 times smaller than  8.5 x [tex]10^{-4}[/tex].

We can also write as:

5 x [tex]10^{-7}[/tex] x 17 x 10 ²  

= 5 x 17 x [tex]10^{-7}[/tex] x 10²

= 85 x [tex]10^{-7 + 2}[/tex]

= 85 x [tex]10^{-5}[/tex]

= 85/10 x 10 x [tex]10^{-5}[/tex]

= 8.5 x [tex]10^{-5 + 1}[/tex]

= 8.5 x [tex]10^{-4}[/tex]

Thus 5 x [tex]10^{-7}[/tex] is 1700 times smaller than  8.5 x [tex]10^{-4}[/tex].

Answer:1

Step-by-step explanation:

The measure of each of the supplementary angles are: 88.6° and 91.4°.

Based on the definition of supplementary angles, the sum of two angles that are supplementary equals 180 degrees.

Given the following:

Let one of the angles equal x

The second angle would be expressed as: x + 2.8

Therefore, we would have the equation:

x + 2.8 + x = 180 [supplementary angles]

2x + 2.8 = 180

2x = 180 - 2.8

2x = 177.2

x = 177.2/2

x = 88.6

Thus:

One of the angles = x = 88.6°

Th second angle is: x + 2.8 = 88.6 + 2.8 = 91.4°

Therefore, the measure of each of the supplementary angles are: 88.6° and 91.4°.
