Area of a figure is the total number of square units in the figure. For a rectangle, it is equal to the product of the length and the width. Assuming that the space given is a rectangle, we can use the formula for the area of a rectangle. We calculate the area of the space as follows:

Area = length x width
Area = 7 cm x 4 cm
Area = 28 cm^2

Therefore, the area of the space you are aiming for would be 28 square centimeters.

What does i^739 equal? explain how you found your answer.
Sophie [7]
<h3>Answer:   -i</h3>

========================================================

Explanation:

i = sqrt(-1)

Lets list out the first few powers of i

  • i^0 = 1
  • i^1 = i
  • i^2 = -1
  • i^3 = i*i^2 = i*(-1) = -i
  • i^4 = (i^2)^2 = (-1)^2 = 1

By the time we reach the fourth power, we repeat the cycle over again (since i^0 is also equal to 1). The cycle is of length 4, which means we'll divide the exponent over 4 to find the remainder. Ignore the quotient. That remainder will determine if we go for i^0, i^1, i^2 or i^3.

For example, i^5 = i^1 because 5/4 leads to a remainder 1.

Another example: i^6 = i^2 since 6/4 = 1 remainder 2

Again, we only care about the remainder to find out which bin we land on.

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

Turning to the question your teacher gave you, we have,

739/4 = 184 remainder 3

So i^739 = i^3 = -i

<h3>-i is the final answer</h3>

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

Side notes:

  • if i^a = i^b, then a-b is a multiple of 4
  • Recall that the divisibility by 4 trick involves looking at the last two digits of the number. So i^739 is identical to i^39.

Divide x^4+3x^3-2x^2+4 by x-2 what is the correct synthetic division and quotinent
frez [133]

Answer:

A

Step-by-step explanation:

The correct divisor is 2. You change the sign of the real number without a variable when that real number is  the divisor.

So - 2 becomes 2 and C and D are both incorrect.

The 0 comes between - 2 and 4 because the x term is 0x. (there isn't one).

That makes B wrong.

The answer is A

mojhsa [17]

Question is Incomplete;

Complete question is given below;

Tracy had a total of $200 to spend while shopping. She has already spent $122 on clothes. She wants to buy some video games that are on sale for $20 each, including tax. Enter the maximum number of video games Tracy can buy with the remaining money.

Answer:

Tracy can buy maximum of 3 video games with the remaining money.

Step-by-step explanation:

Given:

Total money to spend on shopping = $200

Money spend on clothes = $122

Cost of each video game = $20

We need to find the number of Video games she could buy.

Solution:

Let the number of video games be 'x'.

So we can say that;

Money spend on clothes plus Cost of each video game multiplied by number of Video games should be less than or equal to Total money to spend on shopping.

framing in equation form we get;

122+20x\leq 200

Now by subtraction property of Inequality we will subtract both side by 122 we get;

122+20x-122\leq 200-122\\\\20x\leq 78

Now dividing both side by 20 using division property of inequality we get;

\frac{20x}{20}\leq \frac{78}{20}\\\\x\leq 3.9

Hence Tracy can buy maximum of 3 video games with the remaining money.
