Answer:

c) 3/12

Step-by-step explanation:

This is because if we bring 3/12 to its lowest form,

(3/3)/(12/3) = 1/4

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

Explanation:

The graph of y = 5 is the horizontal line through 5 on the y axis. Two points on this line are (0,5) and (1,5).

Similarly, the graph of y = -3 is the same idea, but the horizontal line goes through -3 this time. Two points on this line are (0,-3) and (1,-3)

Let's say we're at (0,5). Directly below this point, on the other line, is (0,-3). The midpoint of (0,5) and (0,-3) is (0,1)

The midpoint of (1,5) and (1,-3) is (1,1)

We form a horizontal line through (0,1) and (1,1). This is the locus of points equidistant from the lines y = 5 and y = -3. It's the middle line halfway between the two given lines. Think of it as the median of the highway (the two shoulders of the highway being y = 5 and y = -3).

So that's why the answer is A) 1 line

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

Side note: any time we have parallel lines like this, the locus of points equidistant from the two lines is always one single line, and it's the median/middle line as described above. This applies to diagonal parallel lines as well, and vertical parallel lines.

Answer:

The angular velocity of the tennis ball is 10 radians per second.

Step-by-step explanation:

The tennis ball can be represented as a particle, the angular momentum ([tex]L[/tex]), in kilogram-square meter per second, of the tennis ball is described by the following formula:

[tex]L = m\cdot r^{2}\cdot \omega[/tex] (1)

Where:

[tex]m[/tex] - Mass of the tennis ball, in kilograms.

[tex]r[/tex] - Radius of gyration, in meters.

[tex]\omega[/tex] - Angular velocity, in radians per second.

If we know that [tex]m = 0.68\,kg[/tex], [tex]r = 0.02\,m[/tex] and [tex]L = 2.72\times 10^{-3}\,\frac{kg \cdot m^{2}}{s}[/tex], then the angular velocity of the tennis ball is:

[tex]\omega = \frac{L}{m\cdot r^{2}}[/tex]

[tex]\omega = \frac{2.72\times 10^{-3}\,\frac{kg\cdot m^{2}}{s} }{(0.68\,kg)\cdot (0.02\,m)^{2}}[/tex]

[tex]\omega = 10\,\frac{rad}{s}[/tex]

The angular velocity of the tennis ball is 10 radians per second.

Answer:

[tex]3\sqrt{85}[/tex] = EC

Step-by-step explanation:

21² + 18² = EC²

441 + 324 = EC²

765 = EC²

[tex]\sqrt{765}[/tex] = EC

Simplified: [tex]3\sqrt{85}[/tex] = EC

y = 4

Step-by-step explanation:

2x + 3y = 6. #1

2x + y = -2. #2

Subtract Eq 2 from Eq 1,

3y - y = 6 - (-2)

2y = 8

or

y = 4

Answer:

y = 4

Step-by-step explanation:

2x + 3y = 6

2x + y = -2

Let's set the second equation equal to y. This means that y will be alone on one side of the equal sign.

2x + y = -2

Subtract 2x from both sides.

y = -2x - 2

Now that we have y as an expression, plug it into the first equation.

2x + 3y = 6

2x + 3(-2x - 2) = 6

Distribute the 3 across the parentheses by multiplying.

2x - 6x - 6 = 6

Combine like terms.

-4x = 12

Divide both sides by -4.

x = -3

Now we have solved x.

To solve for y, plug x back into one of the equations.

y = -2x - 2

y = -2(-3) - 2

Multiply.

y = 6 - 2

Subtract.

y = 4

Check your answer by plugging both values back into the original equations.

2x + 3y = 6

2(-3) + 3(4) = 6

Multiply.

-6 + 12 = 6

Add.

6 = 6

Your answer is correct.

Answer:

x2+2x−15

Step-by-step explanation:

Answer:

x^2 + 2x - 15

Step-by-step explanation:

X × X + 5x - 3x - 3 × 5 =

x^2 + 5x - 3x - 3 × 5 =

X^2 + 2x - 15

also x^2 means x to the 2nd power

Answer:

Let p be the number of pens and let n be the number of notebooks.

4 notebooks + 3 pens cost $96 so 4n + 3p = 96

2 notebooks + 2 pens cost $54 so 2n + 2p = 54

We find n and p by solving the system of linear equations:

4n + 3p = 96

2n + 2p = 54

4n + 3p = 96

4n + 4p = 108 (we multiply this by 2 to cancel out 4n in both equations)

We then subtract the two equations:

(4n + 3p) - (4n + 4p) = 96 - 108

-p = -12

p = 12

So, a pen costs 12 dollars. We can use p to find n. We substitute 12 for p in one of our earlier equations:

2n + 2p = 54

2n + 2(12) = 54

2n + 24 = 54

2n = 30

n = 15

So, a notebook costs 15 dollars and a pen costs 12. Now, we need to find the cost of 8 notebooks and 7 pens:

8n + 7p = ?

8(15) + 7(12) = ?

120 + 84 = 204.

Thus, 8 notebooks and 7 pens cost 204 dollars (why is it so expensive lol).

204

Answer:

x=-8

Step-by-step explanation:

First multiply both sides by 8

-6=-[tex]\frac{7}{8}[/tex]x-13

Next, move the terms so that x is by itself

-48=-7x-104

7x=-104+48

Finally, you can solve

7x=-56

x=-8

Answer:

2/5 or 40 percent

Step-by-step explanation:

All we need to solve this problem are the total number of boys and the total number of girls. Since we already know how many boys there are (6) , let's start by finding the girls, which is marked as b. Looking at the chart, we can tell that

8 + a = b

but we don't know what a is yet. How about we find that out first? If we look vertically, we can see that

a + 4 = 5

so

a = 1.

Now, we can find b.

b = 9

To find the probability of selecting a boy, we have to divide the number of boys by the total number of people.

boys/total = 6 / 15

Simplifying, we get the answer

2/5.

Answer:

3.0 x 10^5 km

Step-by-step explanation:

c = 299,792,458 metres per second

c = 299,792 km per second

1 light second =  299,792 km

To two significant figures

300,000 km

3.0 x 10^5 km

In 1 light second there are [tex]3\times 10^5[/tex] kilometers.

[tex]1 \text{light seconds}=3.0\times 10^5 km[/tex]

Step-by-step explanation:

To find:

Value of 1 light  second into Kilometers

Solution:

Speed of light in space = [tex]3.0\times 10^8 m/s[/tex]

This means that in 1 second light travels [tex]3.0\times 10^8 m/s[/tex].

1 m = 0.001 km

The distance traveled by the light in Km in a second will be:

[tex]3\times 10^8 m= 3\times 10^8\times 0.001 km =3.0\times 10^5 km[/tex]

So, from this, we can conclude that in 1 light second there are [tex]3\times 10^5[/tex] kilometers.

[tex]1 \text{light seconds}=3.0\times 10^5 km[/tex]
