What is the slope of pv? A:1 B:2 C:-2 D:-4

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

Explanation:

Let's say the teacher pulls the two boys out of the line, and stands in their place. So we have 5 girls and 1 teacher making 6 people total.

There are 6! = 6*5*4*3*2*1 = 720 different permutations here. Order matters. This involves the teacher, so let's have him/her step out of the line and have the two boys replace the teacher's position. This guarantees the boys stick together. For any permutation, we have 2 different ways to arrange the boys. So we have 2*720 = 1440 different ways to arrange the students so that the two boys are next to each other.

This is out of 7! = 7*6*5*4*3*2*1 = 5040 different permutations overall (we're arranging 5 girls+2 boys = 7 people).

The probability we're after is going to be 1440/5040 = 2/7

--------

Or you could see it like this

1440 = 2*6!

5040 = 7! = 7*6!

So,

1440/5040 = (2*6!)/(7*6!)

1440/5040 = 2/7

Answer:

4.5

Step-by-step explanation:

The reason is you take the .45 × 10 the 4 will be brought to the left due to the ten pushing it. If it was .45 x 100 it would be 45. Apply that with all decimals x 10 , 100 , 1000 or higher

The jet travels a distance of

(960 km/h) t

after time t, while the light plane travels a distance of

(560 km/h) t

The jet is faster than the light plane, so the distance between them is

(960 km/h) t - (560 km/h) t = (400 km/h) t

so the time it takes for them to be 4560 km apart is

(400 km/h) t = 4560 km

==>  t = (4560 km) / (400 km/h)

==>  t = 11.4 h

Answer:

40%

Step-by-step explanation:

Every week you he buys 4 number of 2 Litres bottle of lemonade.

Thus, let's say cost of each bottle is X.

This means he total cost is 4X

Now, total litres = 4 × 2 = 8 litres

Thus, cost per litre = 4X/8 = ½X

Now, we are told that Last week the bottles on the shelf were limited edition “2.5 litres for the price of 2 litres” bottles ".

This means that now, it is cheaper.

However, the supermarket also had a “buy 3 bottles, get another one free” offer.

Now since he buys 8 litres weekly, now since it's 2.5 L bottle, he will buy 3 since he will be given 1 free for every 3 he buys.

Thus, total litres he is paying for = 2.5 × 3 = 7.5 litres

Thus, cost per bottle is; 3X

Since he is getting 1 bottle free, then total bottle he gets is; 7.5 L + 2.5 L = 10L

Thus;

cost per litre is now; 3X/10

Difference in costs per litre is;

½X - 3X/10 = X/5

percentage of the cost of four bottles of lemonade lower than usual last week = (X/5)/(½X) × 100% = 2/5 × 100% = 40%

Answer: Therefore, the recursive formular is A(n) = A(n - 1) + 9

Step-by-step explanation: (n) = 2 + 9(n - 1) = 2 + 9n - 9  

(n + 1) = 2 + 9(n + 1 - 1) = 2 + 9n = (2 + 9n - 9) + 9 = A(n) + 9

Transformations are used to move a function from one position to another. The new function g(x) is [tex]g(x) = \frac{1}{x-1} - 6[/tex]

Given that

[tex]f(x) = \frac 1x[/tex]

When shifted 6 units down. the rule of transformation is:

[tex](x,f(x)) \to (x,f(x) - 6)[/tex]

So, we have:

[tex]f'(x) = f(x) - 6[/tex]

[tex]f'(x) = \frac 1x - 6[/tex]

When shifted 1 unit left. the rule of transformation is:

[tex](x,g(x)) \to (x -1,f'(x))[/tex]

So, we have:

[tex]g(x) = f'(x - 1)[/tex]

[tex]g(x) = \frac{1}{x-1} - 6[/tex]

Hence, the new function g(x) is [tex]g(x) = \frac{1}{x-1} - 6[/tex]

Answer:

1.10

Step-by-step explanation:

The velocity of the combined cars after the collision is 1.10 m/s.

Velocity is defined as the displacement of the object in a given amount of time and is referred to as velocity.

The momentum of an object is equal to its mass multiplied by its velocity.

The first car has a mass of 1,250 kg and a velocity of 2.24 m/s, its momentum is 1,250 kg x 2.24 m/s = 2,800 kgm/s.

Similarly, since the second car has a mass of 1,300 kg and a velocity of 0 m/s (it is stopped), its momentum is 0 kgm/s.

Therefore, the total momentum of the two cars before the collision is:

⇒ 2,800 kgm/s + 0 kgm/s = 2,800 kg m/s.

After the collision, the two cars stick together and move forward as one unit. We can find the velocity of the combined cars by dividing their total momentum by their total mass.

The total mass of the cars is:

⇒ 1,250 kg + 1,300 kg = 2,550 kg.

So, the velocity of the combined cars after the collision is:

⇒ 2,800 kgm/s / 2,550 kg = 1.098 kgm/s.

To two decimal places, this velocity is 1.10 m/s. Therefore, the correct answer is 1.10 m/s.

Step-by-step explanation:

We have 25.5/3600, and when we convert it to a decimal, we have 0.00708(3), the 3 in the parentheses means the 3 repeats forever. To convert it to percentage, we multiply it by 100, to get 0.708(3). Hope it helps!

Answer: 1.99

Step-by-step explanation: It's about time I tell you how this works. So here it says price PER apple. So PER means we divide 7.96/4 to get 1.99. Now you may be like, How do I know that I do 7.96/4? Why not 4/7.96? Well it says PRICE per APPLE. Price being first so we do 7.96 which is the price, divided by 4 which is the apples. Then we just repeat this process if you want to check your work. So 9.95/5, and 11.94/6

Answer:

I am doing this for the gram say hi

Step-by-step explanation:

a(50) = 238

The constant (diference) = 5

-2 - (-7) = - 2 + 7 = 5

3 - (-2) = 3 + 2 = 5

use formula

a(n) = a + (n - 1)d

a = - 7

n = 50

d = 5

a(50) = - 7 + (50 - 1)5

= - 7 + 49ₓ5

= - 7 + 245

= 238

Answer:

Step-by-step explanation:

Simplifying

3x + 5 = 3x + 7

Reorder the terms:

5 + 3x = 3x + 7

Reorder the terms:

5 + 3x = 7 + 3x

Add '-3x' to each side of the equation.

5 + 3x + -3x = 7 + 3x + -3x

Combine like terms: 3x + -3x = 0

5 + 0 = 7 + 3x + -3x

5 = 7 + 3x + -3x

Combine like terms: 3x + -3x = 0

5 = 7 + 0

5 = 7

Solving

5 = 7

Couldn't find a variable to solve for.

This equation is invalid, the left and right sides are not equal, therefore there is no solution.

Answer: 6 - √35 < 0

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

Answer: (z + 2)(z - 3)

Step-by-step explanation:

First, we have 1 as a coefficient on z², so we multiply that by -6, which gives us -6. Now we must find out what two numbers when multiplied, give us -6, and when added together, give us -1 (z's coefficient). Going through -6's factors, I got -3 and 2 since we need a negative one when they are added together. Now we can input our values:

(z - 3)(z + 2).

Double checking, we get the starting equation, which means our factorization was correct, and so is the solution.

Note: it does not matter which binomial comes first because you will get the same answer regardless of its position.
