Parallelogram is a quadrilateral that has two pairs of parallel sides.

In a parallelogram, opposite sides and angles are equal.

The adjacent angles add up to 180 degrees.

We have,

EB = x - 7

DE = 31

From the figure, we see that,

(1/2)BD = EB = DE

Since the diagonal of a parallelogram bisects each other at its midpoint.

Now,

x - 7 = 31

Adding 7 on both sides.

x = 31 + 7

x = 38

Thus,

x = 38.

Step-by-step explanation:

I can explain what each item is, but I don't know exactly what it's asking

5 is a coefficient. The number attached to the left of the variable/term is always called the coefficient

x is the term/variable. Can always change the outcome, it just depends on the value inputed at that place

3 is a constant, since there's no term attached to it, it will always stay 3

Answer: x = 18

Step-by-step explanation:

Rearrange the terms

70 = 7 + 3.5 × x

Calculate

-3.5x = 7 -70

Divide Both Sides

-3.5x = -63

x = [tex]\frac{-63}{-3.5}[/tex]

x = 18

Answer:

Table 3

Step-by-step explanation:

A linear relationship will have constant rate of change(slope) for all x values

Rate of change = Δf(x)/Δx

where Δf(x) = change in values of f(x)

and Δx = corresponding change in values of x

Only table 3 has this constant rate of change:

This slope of 2 is the same if you take any two pairs of x, f(x) values in that table

Hence constant slope = linear relation

Faults are planar features in rocks where the two sides move past each other due to tectonic forces. However, not all planar features in rocks are faults, as there are other types of planar features that do not involve movement. A planar feature that does not involve movement is called a joint.

A planar feature refers to a surface or boundary within a rock that has a relatively consistent orientation or direction. These features can be caused by a variety of geological processes, such as deformation, metamorphism, or sedimentation. Some examples of planar features in rocks include bedding planes, foliation, and cleavage.

A fault, in particular, is a type of planar feature that forms when tectonic forces cause two sides of a rock to move past each other. This movement can be horizontal, vertical, or a combination of both. Faults can range in size from small fractures in the rock to large features that extend for kilometers. They are a common feature in regions where tectonic forces are actively shaping the Earth's crust, such as along plate boundaries or in areas with active volcanism.

On the other hand, a planar feature that does not involve movement is called a joint. Joints are fractures in rocks that do not result in any significant displacement of the rock on either side of the fracture. They can be caused by a variety of factors, such as cooling and contraction of magma or shrinkage of sediments. Joints can be important in geology because they can influence the way that rocks weather and erode over time.

In summary, a planar feature refers to a surface or boundary within a rock that has a relatively consistent orientation or direction. While faults are a type of planar feature that involves movement between two sides of a rock, joints are planar features that do not involve any significant displacement of the rock on either side of the fracture. Understanding these different planar features is important in geology, as they can provide insight into the geological history of a region and can be used to predict future geological activity.

The equation y = 2(kx - 1)^5 represents a curve. To find the equation of the curve, we need to determine the value of the constant k. To do this, we can use the two points given, (0,1) and (1,8), to find two equations and solve for k.

First, we'll substitute the x-coordinate and y-coordinate of the first point, (0,1), into the equation:

1 = 2(k * 0 - 1)^5

Expanding the right-hand side:

1 = 2(-1)^5

1 = -32

This equation is clearly false, so the point (0,1) does not lie on the curve represented by y = 2(kx - 1)^5.

Next, we'll substitute the x-coordinate and y-coordinate of the second point, (1,8), into the equation:

8 = 2(k * 1 - 1)^5

Expanding the right-hand side:

8 = 2(k - 1)^5

Dividing both sides by 2:

4 = (k - 1)^5

Taking the fifth root of both sides:

2 = k - 1

Adding 1 to both sides:

3 = k

Now that we have the value of k, we can write the equation of the curve:

y = 2(kx - 1)^5

= 2(3x - 1)^5

This is the equation of the curve that passes through the points (0,1) and (1,8).

It's important to note that the original equation y = 2(kx - 1)^5 is only one of an infinite number of curves that can pass through the points (0,1) and (1,8). The process of finding the equation of a curve that passes through specific points is known as curve fitting. The specific equation found in this case is just one possible representation of the curve that passes through the given points.

0.00426 is the probability of being dealt six clubs and three cards with one card .

Describe probability using an example?

A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

                                 The likelihood of an event occurring increases as its probability increases. The flip of a fair (impartial) coin serves as a straightforward illustration.

We will get 9 cards out of 52 cards

Probability of getting 6 clubs is

total we have 13 clubs

no of chances = 13C6

chances of getting 3 cards from 3 other suits

= 39C3

Now, the total probability

= 13C6 * 39C3 / 52C9

= 1716 * 9139 / 3679075400

The solution to the equation cos(x + 2π/3) = √2/2 over the interval

(0, 2π) is [7π/12, 3π/4]

A periodic function has a range that is determined for a fixed interval and a domain that includes all real number values.

Any function that has a positive real integer p such that f (x + p) = f (x), with all x being real values, is said to be periodic.

The given function is cos(x + 2π/3) = √2/2 over the interval (0, 2π).

(x + 2π/3) = cos⁻1(√2/2).

x + 2π/3 = π/4  or 21π/12   (As cos is +ve on I and IV)

Now,

x + 2π/3 = π/4.

x = π/4 - 2π/3.

x = (3π - 8π)/12.

x = - 5π/12.

x = π - 5π/12.

x = (12π - 5π)/12.

x = 7π/12.

And,

Number of bottles of paint needed to paint 70 ornaments is 112.

The area of a three dimensional object on it's outer surface is called the surface area of the object

Each ornament is made up of two identical cones.

A cone has a circular base and a lateral surface

Surface area of base = πr², where r is the radius

Lateral surface area of the cone = πrl, where r is radius and l is slant height.

Total surface area of a cone = πr² + πrl = πr (r + l)

There are 2 identical cones for an ornament.

Surface area of an ornament = 2πr (r + l)

                                                = 2π × 3.3 (3.3 + 8.6)

The probability of being dealt two aces and one of them being the ace of spades is 1 in 221, or 0.45%.

The probability of being dealt two aces and one of them being the ace of spades is 1/221. This is because the chance of the first card being the ace of spades is 1/52 and the chance of the second card being an ace, given that the first card is an ace, is 3/51. Thus, the probability of both cards being aces and one of them being the ace of spades is 1/221.

Mathematically, this can be expressed as P(Ace of Spades, Ace) = P(Ace of Spades) x P(Ace|Ace of Spades) = (1/52) x (3/51) = 1/221.

This means that the probability of being dealt two aces and one of them being the ace of spades is 1 in 221, or 0.45%.

The chance of observing Mississippi after permuting the letters of it and randomly picking a word from that set is 1 in 34032.

The number of words that can be constructed from the letters of the word "Mississippi" is given by the number of permutations of those letters. Since the letters are not unique, we use the formula for permutations with repetition:

n! / (n₁! ×  n₂! ×  ... × nk!)

where n is the total number of letters, and n₁, n₂, ..., nk are the number of times each letter is repeated.

In this case, n = 11 and n₁ = 4, n₂ = 4, n₃ = 2, n₄ = 1.

So, the number of words that can be constructed is 11! / (4! × 4! × 2! × 1!) = 34, 032.

Thus, the chance of observing "Mississippi" is 1 in 34, 032 or approximately 1/34.

The exponential function is [tex]y = 1505.88(0.85)^x[/tex].

The monthly number of defective parts will be less than 500 about 7 months after Jane was hired.

What is an exponential function?

The formula for an exponential function is f(x) = a^x, where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.

To model the monthly number of defective parts, we can use an exponential equation of the form:

[tex]y=a(b)^x[/tex]

Where y is the number of defective parts, x is the number of months after Jane was hired, a is the initial number of defective parts, and b is the common ratio between consecutive months.

To find the values of a and b, use the two data points given -

In the first month, there were 1,280 defective parts, which means that y = 1280 when x = 1.

In the second month, there were 1,088 defective parts, which means that y = 1088 when x = 2.

Substituting these values into the exponential equation -

1280 = a(b)

1088 = a(b)²

Dividing the second equation by the first equation -

1088/1280 = (a(b)²)/(a(b))

0.85 = b

Substituting b = 0.85 into the first equation -

1280 = a(0.85)

1280 = 0.85a

a = 1505.88 (rounded to two decimal places)

So the exponential equation that models the monthly number of defective parts is -

[tex]y = 1505.88(0.85)^x[/tex]

To find when the monthly number of defective parts will be less than 500, we can set y = 500 and solve for x -

[tex]500 = 1505.88(0.85)^x[/tex]

Dividing both sides by 1505.88 -

[tex]0.332 = (0.85)^x[/tex]

Taking the logarithm of both sides (with any base) -

log(0.332) = x log(0.85)

Dividing both sides by log(0.85) -

x = log(0.332) / log(0.85)

x ≈ 6.87

Therefore,  the monthly number of defective parts will be less than 500 about 7 months after Jane was hired.
