What is the slope of the line on the graph. I need help I!!!

Answers

From just looking at the graph we can already notice that the slope is gonna be a negative since the line is going downhill.

So using the Rise Over Run we can calculate the slope, from each point the slope rises 2 and runs -6 (-2/6) then simplify to -1/3

-1/3 is your slope

Martin needs 60 meters of fence to go around a rectangular garden.
The length, l, of the garden is twice its width w.
Three of these equations give the correct value for w.

Which equation does NOT?



2 • w + 2 • 2w = 60


2 • (2w + w) = 60


w + 2w = 60


w + 2w + w + 2w = 60

Answers

w + 2w = 60 would be your answer.

Answer:

w + 2w = 60

Step-by-step explanation:

w + 2w = 60

This equation will not give you the correct value for W because W is the siez or represents the size of the smaller side, since you have 4 sides, 2 small and 2 big, the sum of this 4 sides will be the perimeter, or the total meters of fence needed, since the total meter of fence need is 60 and in the equation you just have 2 sides, the value for W will be double than the real.

If the side length of a square pyramid is triple and the slant height is divided by 5 what would be the formula to find the modified surface area

Answers

If the original side length is "s" and the original slant height is "h", the original surface area is
.. S = (base area) +(lateral area)
.. S = s² +(1/2)*(4s)*h
.. S = s(s +2h)

Now, if we make these replacements: s ⇒ 3s, h ⇒ h/5, we have
.. S' = (3s)(3s +2h/5)
.. S' = 9s² +(6/5)s*h . . . . . . . the formula for the modified area (in terms of original dimensions)

_____
Of course, in terms of the modified dimensions, the formula is the same:

Noel is playing a game where he draws one playing card each out of two stacks of 5 cards. The table below shows all possible sums for the two numbers on the cards.

Answers

Noel is more likely to draw two cards with a sum that is greater than 13.

To determine which outcome is more likely, let's count the number of combinations that meet each criterion.

1. **Sum that is a multiple of 3**:

  - Possible sums: 3, 6, 9, 12

  - Counting the combinations:

    - 3: 1 combination

    - 6: 2 combinations

    - 9: 3 combinations

    - 12: 4 combinations

  - Total combinations: 1 + 2 + 3 + 4 = 10 combinations.

2. **Sum greater than 13**:

  - Possible sums: 14, 15, 16, 17, 18, 19, 20, 21, 22, 23

  - Counting the combinations:

    - 14: 1 combination

    - 15: 2 combinations

    - 16: 2 combinations

    - 17: 3 combinations

    - 18: 2 combinations

    - 19: 3 combinations

    - 20: 2 combinations

    - 21: 3 combinations

    - 22: 1 combination

    - 23: 1 combination

  - Total combinations: 1 + 2 + 2 + 3 + 2 + 3 + 2 + 3 + 1 + 1 = 20 combinations.

Comparing the total combinations, we see that there are more combinations with a sum greater than 13 (20 combinations) than there are combinations with a sum that is a multiple of 3 (10 combinations). Therefore, Noel is more likely to draw two cards with a sum that is greater than 13.

The probable question may be:

Noel is playing a game where he draws one playing card each out of two stacks of 5 cards. The table below shows all possible sums for the two numbers on the cards.

3, 6, 7, 9, 1

1 = 4, 7, 8, 10, 12

4 = 7, 10, 11, 13, 15

6 = 9, 12, 13, 15, 17

8 = 11, 14, 15, 17, 19

12 = 15, 18, 19, 21, 23

Is Noel more likely to draw two cards with a sum that is a multiple of 3 or two cards with a sum that is greater than 13?

Noel is more likely to draw two cards with a sum greater than 13, as there are 37 combinations compared to 11 combinations for multiples of 3.

To determine whether Noel is more likely to draw two cards with a sum that is a multiple of 3 or two cards with a sum that is greater than 13, we can analyze the table provided.

1. Sum that is a multiple of 3:

  - There are several combinations of card values that result in a sum that is a multiple of 3. We can count these combinations from the table:

    - (3, 4), (3, 7), (3, 9), (3, 12)

    - (6, 7), (6, 10), (6, 12)

    - (7, 8), (7, 11)

    - (9, 10), (9, 13)

    - (11, 12)

2. Sum greater than 13:

  - We need to count the combinations of card values that result in a sum greater than 13:

    - (6, 8), (6, 10), (6, 11), (6, 12), (6, 13), (6, 15), (6, 17)

    - (7, 8), (7, 9), (7, 10), (7, 11), (7, 12), (7, 13), (7, 15), (7, 17), (7, 19)

    - (9, 10), (9, 11), (9, 12), (9, 13), (9, 15), (9, 17), (9, 19)

    - (11, 12), (11, 13), (11, 15), (11, 17), (11, 19)

    - (12, 13), (12, 15), (12, 17), (12, 19)

    - (13, 15), (13, 17), (13, 19)

    - (15, 17), (15, 19)

    - (17, 19)

After counting the combinations, we can compare the number of combinations in each category:

1. Sum that is a multiple of 3:

  - Total combinations: 11

2. Sum greater than 13:

  - Total combinations: 37

Comparing the totals, we can see that Noel is more likely to draw two cards with a sum that is greater than 13, as there are more combinations resulting in this outcome.

A. AB, AC, BC
B. AC, AB, BC
C. BC, AB, AC
D. AB, BC, AC

Answers

1. The sum of of the interior angles of a triangle is 180°.

 2. Keeping this on mind, you have:

 A+B+C=180

 A=11x-4
 B = 4x-11
 C=63-4x

 3. When you substitute these values, you obtain:

 A+B+C=180
 11x-4+4x-11+63-4x=180
 11x+48=180
 11x=180-48
 11x=132
 x=132/11
 x=12

 3. Therefore:

 A=11(12)-4
 A=128°

 B = 4(12)-11
 B=37°

 C=63-4(12)
 C=15°

 5. The answer is:

 A. AB, AC, BC

The diagram is a hat box that is designed with the shape of a regular octagon inside and a rectangle outside. Find the value of x. Please explain.

Answers

in a regular octagon all the interior angles are of the same value. 
sum of the interior angles in octagon = (n-2) *180°
n - number of sides, in this case, n = 8
interior angles sum = (8-2)*180° = 6*180° = 1080°
since there are 8 equal angles = 1080/8 = 135°
Angle x + one interior angle of the octagon = 180 ° (as its a straight line)
x + 135 = 180
x = 45°

How many 4-sequences on {0..9} do not begin with 0?

Answers

I take a [tex]n[/tex]-sequence to mean any permutation of the digits 0-9 of length [tex]n[/tex]. Furthermore, I'm assuming no number can be repeated.

If that's the case, then for any 4-sequence, the first digits place (leftmost) has 9 possible choices (1-9). Once that number is used up, we have 9 numbers left in the pool of digits, from which we select a 3-sequence. The number of possible 3-sequences would be [tex]\dfrac{9!}{3!}=60,480[/tex]. Multiply this by 9 (to account for the first digit's possibilities) and we get a grand total of [tex]\dfrac{9\times9!}{3!}=544,320[/tex] possible 4-sequences on [tex]\{0,\ldots,9\}[/tex].

There are 9000 possible 4-sequences that do not begin with the digit 0.

The question asks how many 4-sequences on the set {0..9} do not begin with 0. To solve this, we need to consider the number of possible options for each of the four positions in the sequence, knowing that the first digit cannot be 0.

For the first position, there are 9 options (1-9), since 0 is not allowed. For the next three positions, each can be any of the 10 digits (0-9), since there are no restrictions. Thus, the total number of such sequences is the product of the number of options for each position.

9 options (1st position) x 10 options (2nd position) x 10 options (3rd position) x 10 options (4th position) = 9 x 10 x 10 x 10 = 9000.

So, to find how many 4-sequences do not begin with 0, multiply the number of choices for each position: 9 (first position, cannot be 0) x 10 (second position) x 10 (third position) x 10 (fourth position), resulting in 9000 such sequences.

Write the following decimal number in its equivalent fraction form. Show all work for full credit.
0.8(repeating)

Answers

Let x=0.8888... 

x=0.8888 Start with the given equation 

10x=8.8888 Multiply both sides by 10. The goal is to move the decimal point to the next repeating portion (which is just one spot to the right) 



 Now subtract the equation x=0.8888 from 10x=8.8888 to get 
10x-x=8.8888-0.8888 

9x=8 Combine like terms. Notice how the decimal portions cancel out. 

x=8/9 Divide both sides by 9 to isolate x 

So the answer is x=8/9 which means that 8/9=0.8888 (where the 8's repeat)
 
Final answer:

To write the decimal number 0.8(repeating) as a fraction, use the concept of an infinite geometric series and convert it to an equation. Multiply both sides of the equation by 10 to eliminate the decimal point and subtract the original equation to eliminate the repeating part. Finally, divide by 9 to get the equivalent fraction form.

Explanation:

To write the decimal number 0.8(repeating) as a fraction, we can use the concept of an infinite geometric series. Let's assume the repeating decimal as x: x = 0.8(repeating). Now, multiply both sides of the equation by 10 to remove the decimal point: 10x = 8(repeating). Next, subtract the original equation from this new equation to eliminate the repeating part: 10x - x = 8(repeating) - 0.8(repeating). Simplifying these expressions gives us: 9x = 7.2. Finally, divide both sides of the equation by 9: x = 7.2/9. Therefore, the equivalent fraction form of 0.8(repeating) is 7.2/9.

Find the differential of the function. v = 2y cos(xy)

Answers

Given a function f(x,y), the differential of f is given by
[tex]df = f_x dx + f_y dy[/tex]
where [tex]f_x[/tex] is the derivative of f(x,y) with respect to x, while [tex]f_y[/tex] is the derivative of f(x,y) with respect to y.

The function of our problem is[tex]f(x,y)=2y \cos(xy)[/tex]
The derivative in x is
[tex]f_x = 2y(-y \sin (xy))=-2y^2 \sin (xy)[/tex]
The derivative in y is
[tex]f_y = 2 \cos (xy) + 2y (-x \sin (xy))=2 \cos (xy) - 2xy \sin (xy)[/tex]

So, the differential of f(x,y) is
[tex]df= -2y^2 \sin (xy) dx + (2 \cos (xy) - 2xy \sin (xy))dy[/tex]

The differential of the function v = 2y cos(xy) is found using the product rule and the chain rule, yielding dv = 2 cos(xy) dy - 2y sin(xy) (xdy + ydx), which accounts for changes with respect to both x and y.

To find the differential of the function v = 2y cos(xy), we'll need to apply the product rule and the chain rule. The product rule states that the differential of a product of two functions is d(uv) = u dv + v du. The chain rule is used when differentiating composite functions, and it implies that d/dx (f(g(x))) = f'(g(x)) * g'(x).

Applying the product rule, we get:

dv = cos(xy) * d(2y) + 2y *d(cos(xy)).The differential d(2y) is simply 2 dy.For d(cos(xy)), we use the chain rule and get -sin(xy) * d(xy), which further expands to -sin(xy) * (xdy + ydx) by applying the product rule again.

Combining these, the differential dv becomes:

dv = 2 cos(xy) dy - 2y sin(xy) (xdy + ydx).

This equation represents the total differential of the function v with respect to both x and y.

For implicit differentiation examples like in equation In(xy) = x2y3 or systems of differential equations, understanding and applying the product rule, chain rule, and implicit differentiation are essential to calculate derivatives and solve the equations.

A cardboard sheet is cut in the shape of a triangle, with vertices at (0,0), (20,0), and (3,4) units. the thickness of the sheet is uniform. what is the x-coordinate of its center of mass?

Answers

This problem can be solved in two ways, the long way, or the short way.

1. The long way
We know that the base of the triangle is along the x-axis, and the length of the base is 20.
The centre of mass is located at 2/3 of the distance from vertex (3,4) along the median, which cuts the base at (10,0).
Therefore the centre of mass is located at
x=3+(10-3)*2/3=23/3
y=4/3

2. The short way
It turns out that the centre of mass of a triangle sheet is located at the mean of the coordinates of the three vertices, i.e.
CG=((0+20+3)/3, (0+0+4)/3)=(23/3, 4/3)  as before.
