Which equation is equivalent to the following?
2x^2 - 12x + 2y^2 + 20y - 28 = 0

1) 2(x-3)^2 +2( y+5)^2=44
2) 2(x-3)^2+2(y+5)^2=60
3) 2(x-3)^2+2(y+5)^2=62
4) 2(x-3)^2+2(y+5)^2=96

Answers

Answer 1

Answer:

Therefore, the equivalent expression is: 2*(x - 3)² + 2*(y + 5)² = 96. Number 4)

Step-by-step explanation:

In order to find the equivalent expression, lets first factor the common term, which is "2":

2*(x² - 6*x + y² + 10 *y - 14) = 0

If we look closely to the terms that have "x" and "y", they both have a square structure, therefore we can complete the squares by manipulating the indepent term. Let's first check the term with "x" and "y":

x² - 6*x + c² = x² - 2*3*x + c² = (x - c)²

y² + 10*y + d² = y² + 2*5*y + d²= (y + d)²

In order to complete the squares, c must be equal to 3 and d must be equal to 5. We can arrange that, by summing and subtracting these numbers squared, we have:

2*(x² - 6*x + 3² + y² + 10 *y +5² - 14 - 3² - 5²) = 0

2*(x² - 6*x + 3²) + 2*(y² + 10*y + 5²) -28 - 18 - 50 = 0

2*(x - 3)² + 2*(y + 5)² = 96

Therefore, the equivalent expression is: 2*(x - 3)² + 2*(y + 5)² = 96

Answer 2

Answer:

2*(x - 3)² + 2*(y + 5)² = 96.

Statements second statements third, and statement fifth is correct as per the conditional relative frequency table.

What is a relative frequency?

It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the frequency cell by the total frequency.

As per the relative frequency table, the correct statements are:

Eve's table shows that those who enjoy dancing are likely girls. Bob's table shows that boys are likely to not enjoy dancing. The percentage of someone being a girl, given that the person enjoys dancing is lower than the percentage that someone enjoys dancing, given that the person is a girl.

Thus, statements second statements third, and statement fifth is correct as per the conditional relative frequency table.

10m + 40 = 9m + 27

10m - 9m = 27 - 40

m = -13

Answer:

m = - 13

Step-by-step explanation:

2/3 (m + 4) = 1/5 (3m+9)

2/3m + 8/3 = 3/5m + 9/5

2/3m - 3/5m = 9/5 - 8/3

10/15m - 9/15m = 27/15 - 40/15

1/15m = - 13/15

Step 1: Simplify both sides of the equation.

−2(3x)+1=7−6x

−6x+1=7+−6x

−6x+1=−6x+7

Step 2: Add 6x to both sides.

−6x+1+6x=−6x+7+6x

1=7

If you square a googol, how many zeros will the answer have? Show your reasoning.

Answers

200 zeros

Step-by-step explanation:

1 googol is the number 1 followed by a hundred zeros, right? Right. Using 'Laws of Indices', for instance, 10^2=100, ie 10×10=100. The number of zeros will always be the sum of the number of zeros of the multiplier and multiplicand. More example, 100×100=10000. So, I think it's reasonable to say that 1 googol×1 googol= the number one followed by two hundred zeros ‍♀️

The Service Club is choosing members at random to attend conferences in Sheboygan, Madison, La Crosse, and Green Bay. There are 15 members in the club, how many ways can they choose someone to go to the Sheboygan conference, someone different for the Madison conference, someone else for La Crosse, and one last person for Green Bay? SHOW YOUR WORK.

Answers

Answer:

There are 32760 ways to pick the members

Step-by-step explanation:

For the first place you have 15 possibilities, since every member of the club is available. For Madison you will have only 14, since you cant pick the same member than the one you picked for Sheyoygan. For the same argument, you will have 13 possibilities available for La Crosse, and only 12 for Green Bay.

We have to pick a combination using the possibilities that we have, thus, you have to multiply all 4 possibilities toguether to find the amount of ways to choose members to attend the conferences. This means that you will have a total of 15*14*13*12 = 32760 possibilities in total.
