The equation of a circle is (x+2)2 + (y-3)2 =9. What are the coordinates of the center of this circle?

Zoe's Fish tank holds 27 L of water she uses a 3L container to fill the tank how many times does she have to fill the three litt

Marianna [84]

<h2>Answer:</h2>

Zoe's Fish tank holds 27 L of water, so this is the capacity of the tank. On the other hand, Zoe uses a 3L container in order to fill the tank, so the question is how many times does she have to fill the three litter container in order to fill the fish tank? Let's solve this as follows:

First time:

She pours 3L

Second time:

She pours another 3L, but she previously poured 3L, so she has poured 6L

Third time:

She pours another 3L, but she previously poured 6L, so she has poured 9L

Fourth time:

She pours another 3L, but she previously poured 9L, so she has poured 12L

Fifth time:

She pours another 3L, but she previously poured 12L, so she has poured 15L

Sixth time:

She pours another 3L, but she previously poured 15L, so she has poured 18L

Seventh time:

She pours another 3L, but she previously poured 18L, so she has poured 21L

Eighth time:

She pours another 3L, but she previously poured 21L, so she has poured 24L

Ninth time:

She pours another 3L, but she previously poured 24L, so she has poured 27L

<em>According to this, she needs to pours the </em><em>3L </em><em>container nine times in order to fill the fish tank. This can also be solved dividing </em><em>27L/3L= 9</em>

The number of employees working for Widget Wonders in 1997 was 17,697, with an expected decrease of 2.2% per year. At the percen

Veronika [31]

In 1997 = 17697

Because, each year, the number of employees is expected to decrease by 2.2%, find 2.2% of 17697 and subtract from the number.

2.2/100 x 17697 = 38933.4/100 = 389.334

^that was calculating 2.2% of 17697. Now we subtract:

17697.000
- 389.334
17307.666 =

Round to the nearest whole number = 17308

Answer: in 1998, the expected number of workers is 17308

5y + 7 < = -3
5y < = -3 - 7
5y < = -10
y < = -10/5
y < = -2

3y - 2 > = 13
3y > = 13 + 2
3y > = 15

5. Which of the following is the equation of a line. that passes through the points (0.8) and (6.4)7 Use of

andriy [413]

See in the explanation

<h2>Explanation:</h2>

In this exercise, <em>we have the following points:</em>

$(0.8) \\ \\ (6.4)$

And <em>the following linear equations:</em>

$(1) \ y=-x+8 \\ \\ (2) \ y=\frac{3}{2}x+6 \\ \\ (3) \ y=-\frac{4}{5}x+4 \\ \\ (4) \ y=\frac{1}{2}x+8$

When plotting these graphs, we find the following facts:

We see the graph in the first figure below. The graph only passes through the point (0, 8)

This is the second graph below. The graph passes neither through point (0, 8) nor (6, 4)

This is the third graph below. The graph passes neither through point (0, 8) nor (6, 4)

This is the fourth graph below. The graph only passes through the point (0, 8)

So, <em>there is no any equation of the line that passes through the points (0.8) and (6.4) at the same time.</em>
