7. Given the diagram below, what is the length of side x?

To write the point (1, 2) on a graph, you would first locate the point on the x-axis where x = 1, and then go up 2 units on the y-axis.

The point (1, 2) is on the Cartesian plane and it represents the coordinates of a point in the 2-D space. This point is located 1 unit to the right of the y-axis and 2 units above the x-axis.

It can be represented graphically as a point on a coordinate plane where the x-coordinate is 1 and the y-coordinate is 2.

On the graph, you can plot the point by first drawing the x and y axes and their respective scales, then place a dot on the point (1,2) which represents the coordinates of the point.

The maximum deflection of the simply supported beam, given the applied load P, the length of the beam L, the Young's Modulus E of the beam material, and the moment of inertia I, is equal to (5*P*L^3)/1536.3*10^15 m.

The maximum deflection of the simply supported beam is given by:

Maximum deflection = (5PL^3)/(384EI)

where P is the load applied to the beam, L is the length of the beam, E is the Young's Modulus of the beam material, and I is the moment of inertia of the beam.

Substituting the given values into the equation, we get:

Maximum deflection = (5*P*L^3)/(384*200*10^9*39.9*10^6)

= (5*P*L^3)/(1536.3*10^15)

The position number for term 47 is 269.

This is an arithmetic sequence since each term has a common difference. Let us test it.

The difference between 1st and 2nd terms is

-7 + d = -1

d = -1 + 7

  = 6

Now we check the difference for term

The difference between 3rd and 4th terms is

5 + d = 11

d = 11 – 5

  = 6

So the difference is the same so we can apply a common equation for arithmetic sequence

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + d ( n - 1 )

Where :

[tex]a_{n}[/tex] = number at term n

[tex]a_{1}[/tex] = first number of sequence

d = difference for each number sequence

n = term

From the question, we need to find the number at position term 47

Answer:

Step-by-step explanation:

The inequality that represents all the solutions of 10(3x + 2) > 7(2x − 4) is 10(3x + 2) > 7(2x − 4). To solve this inequality, first we must combine like terms on each side of the inequality. On the left side, 10(3x + 2) becomes 30x + 20. On the right side, 7(2x − 4) becomes 14x − 28. After combining the like terms, the inequality becomes 30x + 20 > 14x − 28. Next, we must subtract 14x from both sides of the inequality. On the left side, 30x + 20 becomes 16x + 20. On the right side, 14x − 28 becomes −28. After subtracting 14x from both sides, the inequality becomes 16x + 20 > −28. Finally, we must subtract 20 from both sides of the inequality. On the left side, 16x + 20 becomes 16x. On the right side, −28 becomes −48. After subtracting 20 from both sides, the inequality becomes 16x > −48. To solve the inequality, we must divide both sides of the inequality by 16. On the left side, 16x becomes x. On the right side, −48 becomes −3. Therefore, the solution to the inequality is x > −3.

By analyzing the given graph, we can see that the rate of change of the linear equation is 8.

A general linear equation can be written as:

y = a*x + b

Where a is the slope (also known as the rate of change, this is what we are looking for here) and b is the y-intercept.

If the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope can be written as:

a = (y₂ - y₁)/(x₂ - x₁)

Here we can see the points:

(1, 28) and (2, 36) and we can use these two to find the slope.

a = (36 - 28)/(2 - 1)

a = 8

So the slope (thus, the rate of change) is 8.

Given: QR = QS (by given)

We are to prove: LS = ZR

Proof:

Since QR = QS, by the SAS (Side-Angle-Side) congruence postulate, we know that triangle QRS is congruent to triangle QSZ (both have two equal sides and included angle).

By the AAS (Angle-Angle-Side) congruence postulate, we know that if two angles of one triangle are congruent to two angles of another triangle, and the included side is congruent, then the two triangles are congruent.

Therefore, by using AAS congruence, we can say that triangle QRS is congruent to triangle QSZ.

By the CPCTC (Corresponding parts of congruent triangles are congruent), we know that if two triangles are congruent, then their corresponding sides are congruent.

Therefore, LS is congruent to ZR.

Therefore, we have proved LS = ZR

Note: The above proof uses the properties of congruence of triangles, if the student is not familiar with this, it might be challenging for them.

The wood fragment is 11,460 years old by C-14 dating if only 25% of the amount the tree had when it was alive is left.

The process of carbon-14 dating can be used to determine the age of an organic material such as wood. Carbon-14 is a radioactive isotope of carbon that is present in all living organisms. When an organism dies, the carbon-14 begins to decay at a known rate, and the amount of carbon-14 in the material decreases over time. By measuring the amount of carbon-14 remaining in a sample, it is possible to determine how long ago the organism died.

If the analysis shows that the C-14 has been reduced to 25% of the amount the tree had when it was alive, it means that 75% of C-14 has decayed, and the material is therefore 75% of its way through its radioactive decay.

Carbon-14 has a half-life of 5,730 years, which means that after 5,730 years, half of the carbon-14 in a sample will have decayed. To find the age of the wood fragment, you would need to multiply the sample's decay percentage (75%) by the material's half-life (5730 years) to get the number of years that have passed.

[tex]t = \frac{5730\ ln(0.25)}{-ln2}[/tex]

Where t is the number of years to decay to 25%.

The ratio of water, sucrose, and saline solution needed is 1000:199:271 in its simplest form.

The amount of water, sucrose, and the saline solution used can be expressed as a ratio in its simplest form by finding the greatest common divisor (GCD) of the three quantities and dividing each by it.

1l of water = 1000 ml of water.

Let's find the GCD of the three quantities:

GCD(199,271,1000) = 1

So we can express the amount of water, sucrose, and saline solution needed as a ratio in its simplest form by dividing each of the three quantities by 1

Water : Sucrose : Saline solution = 1000 : 199/1 : 271/1 = 1000:199:271

From the given line equation, the closet point to the origin is (-6/5, 3/5).

Here we have given that the point on the line y=2x+3 that is closest to the origin.

As we all know that the closest point from origin will be the perpendicular distance from origin to the line.

Here we need to find an equation of the perpendicular from (0,0) on y = 2x + 3.

As we all know that the standard form of the equation is in slope-intercept form is written as,

=> y = mx + c

While we comparing this with the given equation, then we get the value of the Slope that is m = 2 and the Slope of the perpendicular is calculated as,

=> - (1/m) = -1/2

Now, we have to write the equation of the perpendicular is found by using the formula,

=> (y - y1) = m (x - x1)

Apply the value on the equation, then we get,

=> y - 0 = (-1/2) (x - 0)

=> y = (-1/2)x

therefore, the resulting perpendicular equation is written as,

=> 2y + x = 0 ----------------(2)

When we solving (1) and (2), then we get,

=> 5y = 3

Therefore, y = 3/5

And the value of x is calculated as

=> x + 2(3/5) = 0

=> x = -6/5

So the point on the line is (-6/5, 3/5).
