The coordinates of the point X on the line segment is (-2/7, 48/7).

Given that, a point X on a segment with endpoints W(-2, 9) and Y(2, 4) partitions the segment in a 3:4 ratio.

Let us say, we have a point P(x,y) that divides the line segment with marked points as A (x1,y1) and B(x2,y2). To find the coordinates, we use the section formula, which is mathematically expressed as:

P(x, y) = P(x, y) = [(mx₂+nx₁)/(m+n), (my₂+ny₁)/(m+n)]

Here, P(x, y) = [(3×2+4×(-2))/(3+4), (3×4+4×9)/(3+4)]

= (-2/7, 48/7)

Therefore, the coordinates of the point X on the line segment is (-2/7, 48/7).

The solution to the given differential equation is [tex]y = 2x + Ce^{-x/2},[/tex]

where C is an arbitrary constant.

We have,

To solve the given first-order linear differential equation:

dy/dx + (1/2)y = 2 + x

We can use the integrating factor method.

The integrating factor (IF) is given by:

[tex]IF = e^{\int{(1/2)}dx}[/tex]

[tex]= e^{x/2}[/tex]

Multiplying both sides of the equation by the integrating factor:

[tex]e^{x/2} \times dy/dx + (1/2)e^{x/2} \times y = (2 + x)e^{x/2}[/tex]

The left-hand side can be simplified using the product rule of differentiation:

[tex]d/dx (e^{x/2} \times y) = (2 + x)e^{x/2}[/tex]

Integrating both sides with respect to x:

[tex]\int{d/dx} (e^{x/2} \times y) dx = \int{(2 + x)e^{x/2}} dx[/tex]

[tex]e^{x/2} \times y = \int{(2e^{x/2} + xe^{x/2}} dx\\= 2\int{e^{x/2}} dx + \int{xe^{x/2}} dx[/tex]

Using the integration rules, we find:

[tex]e^{x/2} \times y = 4e^{x/2} + 2xe^{x/2} - 4e^{x/2} + C\\= 2xe^{x/2} + C[/tex]

Dividing both sides by [tex]e^{x/2}:[/tex]

[tex]y = 2x + Ce^{-x/2}[/tex]

Answer:

3700kg

Step-by-step explanation:

Use this idea.

"percent" means "per hundred"

Over 100% is more than what you started with.

To do math with percents, change them to a decimal.

145% is 1.45

1.45x = 5365

divide both sides by 1.45

x = 3700

The original value is calculated by dividing 5365 kg by 1.45, which gives approximately 3700 kg as the result.

To find the original value, you need to understand that 145% is equivalent to 145/100 or 1.45. This means that what we have (5365 kg) is 1.45 times the original value. So, to find the original value, we need to divide 5365 kg by 1.45.

Step 1: Convert 145% to a decimal by dividing 145 by 100 to get 1.45.

Step 2: Divide 5365 kg by 1.45.

The calculation looks like this: 5365 kg / 1.45 = 3700 kg (approximately)

So, the original value is about 3700 kg.

No, there are three different values for x when each expression is set equal to 10.

Answer:  To estimate the value of csc 120° using the graph of y = csc x, we can locate the point on the graph that corresponds to 120° and read the y-coordinate (csc value) from there.

On the graph of y = csc x, we observe that the csc value is undefined at x = 0° and x = 180° due to vertical asymptotes. Additionally, csc x has maximum and minimum points at multiples of 90°.

To estimate csc 120°, we can look for the nearest maximum or minimum point on the graph. The closest maximum point to 120° is at 90°, and the closest minimum point is at 180°.

Since the maximum value of csc x is 1, we can estimate csc 120° to be approximately 1.

Therefore, the estimated value of csc 120° is 1 (rounded to the nearest tenth).

Answer:

The point U' is (-6, -2).

Step-by-step explanation:

The reflection of point U over the x-axis is the point U' with the same x-coordinate but a y-coordinate that is the opposite of U's y-coordinate. Since the y-coordinate of point U is 3, the y-coordinate of the reflected point U' will be -3. Therefore, the coordinates of U' are (-2, -3).

The graph should show U at the point (2, 3) and U' at the point (2, -3) after being reflected over the x-axis.

The value of x that satisfies the equation -8 + 5(2x + 1) = -(7x + 9) + x is x = 3/4.

To solve the equation -8 + 5(2x + 1) = -(7x + 9) + x, we will simplify the expression step by step and solve for the value of x.

Distribute 5 to the terms within the parentheses: -8 + 10x + 5 = -(7x + 9) + x

Combine like terms on both sides of the equation: -8 + 5 + 10x = -7x - 9 + x

Simplifying further, we have: -3 + 10x = -6x - 9

To eliminate the negative sign on the right side of the equation, we can multiply every term by -1: -3 + 10x = -6x - 9 * -1

This simplifies to: -3 + 10x = -6x + 9

Next, we want to isolate the x terms on one side of the equation and the constant terms on the other side. We can do this by adding 6x to both sides: -3 + 10x + 6x = -6x + 9 + 6x

Simplifying further: 16x - 3 = 9

To isolate the x term, we need to eliminate the constant term on the left side. We can do this by adding 3 to both sides: 16x - 3 + 3 = 9 + 3

Simplifying further: 16x = 12

Finally, we solve for x by dividing both sides of the equation by 16: (16x)/16 = 12/16

The equation simplifies to: x = 3/4

Therefore, the value of x that satisfies the equation -8 + 5(2x + 1) = -(7x + 9) + x is x = 3/4.

Gabe uses a total of 10 feet of string for all his puppets in art class.

In art class, Gabe is creating marionettes by attaching strings to puppets. He ties 6 inches of string to the head of each puppet and 9 inches of string to each of the 2 arms. Since Gabe has a total of 5 puppets, let's calculate the total amount of string he uses.

For each puppet, Gabe uses 6 inches of string for the head. Since he has 5 puppets, the total string used for the heads is 5 puppets × 6 inches/puppet = 30 inches.

Similarly, Gabe uses 9 inches of string for each arm of each puppet. Since each puppet has 2 arms, he uses a total of 2 arms × 9 inches/arm = 18 inches of string per puppet. For 5 puppets, the total string used for the arms is 5 puppets × 18 inches/puppet = 90 inches.

To find the total string used, we add the string used for the heads and arms: 30 inches + 90 inches = 120 inches.

Since there are 12 inches in a foot, the total string used by Gabe is 120 inches / 12 inches/foot = 10 feet.

To calculate the total surface area of a triangular prism, we need to find the area of each face and add them up.

The triangular faces have base 5cm and height 12cm, so each one has an area of:

(1/2) x 5cm x 12cm = 30cm²

There are two of these faces, so their combined area is:

2 x 30cm² = 60cm²

The rectangular faces have dimensions 5cm x 10cm and 5cm x 13cm, so their areas are:

5cm x 10cm = 50cm²

5cm x 13cm = 65cm²

Again, there are two of these faces, so their combined area is:

2 x (50cm² + 65cm²) = 230cm²

Finally, we add up the areas of all the faces to get the total surface area:

60cm² + 230cm² = 290cm²

Therefore, the total surface area of this triangular prism is 290cm².

adilenechapa22 wrote the correct answer first so they deserve the Brainiest for the question.  However, I can help you understand how we get to the answer.

Step 1:  Isolate y in 4x + y = 16 by subtracting 4x from both sides to prepare for the substitution:

(4x + y = 16) - 4x

y = -4x + 16

Step 2:  Substitute this equation for y in the first equation to first solve for x:

6x + 5(-4x + 16) = 38

6x - 20x +80 = 38

-14x + 80 = 38

-14x = -42

x = 3

Step 3:  Plug in 3 for x in 4x + y = 16 to solve for y:

4(3) + y = 16

12 + y = 16

y = 4

Congruent means that a triangle has the same angle measures and side lengths of another triangle.

SAS congruence theorem: If two sides and the angle between these two sides are congruent to the corresponding sides and angle of another triangle, then the two triangles are congruent. Congruent triangles: When two triangles have the same shape and size, they are congruent.

Let's look at A first.

The triangle on left, we know 40 and 30 degree angles. So 3 all angles together = 180, so the 3rd angle = 180-30-40 = 110.

Now look at the triangle on the right. The angle shown is 110! This angle is between the sides marked with || and ||| marks, indicating that those two sides are the same length between both triangles.

Therefore both triangles are the same by Side-Angle-Side or SAS.

Now look at B.

It's a right triangle. We are missing 1 side of each triangle.

Let's solve for the missing "leg" of the triangle on the right. The pythagorean theorem says that a^2 + b^2 = c^2 where a and b are the 'legs' or sides of the triangle and c is the hypotenuse (always the longest length opposite the right angle).

so 2^2 + b^2 = 4^2

4 + b^2 = 16

b^2 = 16-4

b^2 = 12

That missing side is the [tex]\sqrt{12}[/tex].

This does NOT match the triangle on the left.

Theses two triangles are NOT congruent.

To determine whether the Law of Sines or the Law of Cosines is needed to solve the triangle, we can compare the given information with the formulas for each law.

The Law of Sines states:

a / sin(A) = b / sin(B) = c / sin(C)

The Law of Cosines states:

c^2 = a^2 + b^2 - 2ab * cos(C)

In this case, we are given the lengths of all three sides of the triangle (a = 6.0, b = 7.7, c = 13.6). Therefore, we have enough information to use the Law of Cosines to solve the triangle.

Using the Law of Cosines, we can find the measures of the angles:

c^2 = a^2 + b^2 - 2ab * cos(C)

(13.6)^2 = (6.0)^2 + (7.7)^2 - 2 * 6.0 * 7.7 * cos(C)

184.96 = 36 + 59.29 - 92.4 * cos(C)

184.96 = 95.29 - 92.4 * cos(C)

92.67 = -92.4 * cos(C)

cos(C) ≈ -1

Since the cosine of an angle cannot be greater than 1 or less than -1, it is not possible for the given triangle to have an angle with a cosine of -1. Therefore, the triangle is not solvable with the given side lengths.

In this case, the Law of Cosines is needed, but the triangle cannot be solved with the given information.
