Step-by-step explanation:

Let's factor out first. 2(-5x+4)+4x-5 = -10x+8+4x-5. If we combine like terms, -10x+8+4x-5 is -6x+3. Now our equation looks like this:

-6x+3 = -3.

If we move over the 3 on the left to the right side, we have -6x = -6. Divide both sides by -6, and we get our answer.

x = 1

No, Green's theorem cannot be applied to the given line integral -5x dx + 3y dy / (x² + y⁴) over the unit circle x² + y² = 1, because C is not positively oriented.

In order to apply Green's theorem, the curve must be a simple, closed, and positively oriented boundary of a region with a piecewise smooth boundary, and the vector field must have continuous partial derivatives in the region enclosed by the curve.

In this case, while the unit circle is a simple and closed curve with a smooth boundary, it is not positively oriented since the orientation is counterclockwise, whereas the standard orientation is clockwise.

Therefore, we cannot apply Green's theorem to this line integral.

The congruence theorem that can be used to prove that the triangles are congruent is F. Not enough information is given to prove that the triangles are congruent

If all three corresponding sides are equal and all three corresponding angles are equal in measure, two triangles are said to be congruent.

According to the Angle-Side-Angle Theorem (ASA), if two angles and their included side are congruent to two angles and their included side, then these two triangles are congruent.

The hypotenuse is always the opposite side of the right angle. The legs of the triangle are the other two sides of a right triangle. Because a right triangle has two legs and a hypotenuse, it is also known as a hypotenuse-leg (or HL) triangle.

In this situation, enough information aren't given about the triangles. Therefore, the correct option is F.

A tangent line is line GJ.

A secant line is line HF.

A chord is line GF.

In Mathematics and Geometry, the chord of a circle can be defined as a line segment that typically join any two (2) points on a circle. This ultimately implies that, a chord simply refers to the section of the line that is used for connecting two (2) separate points on a circle such as line GF.

In Mathematics and Geometry, a secant line can be defined as a type of line that intersects the edge of a circle twice i.e it goes through the interior of the circle twice and intersects its boundary twice such as line HF.

In conclusion, a tangent line is a type of line that lies outside of a circle and intersects the edge of a circle exactly once i.e it touches the outside of the circle only once such as line GJ.

Step-by-step explanation:

A boat leaves port and follows a course of N72°E at 6 knots for 3 hours and 20 minutes. Then, it changes to a new course of S27°E at 12 knots for 5 hours. We need to determine the distance of the boat from the port.

To find the distance of the boat from the port, we can break down the boat's journey into two segments and calculate the distance traveled in each segment.

In the first segment, the boat travels at a speed of 6 knots for a duration of 3 hours and 20 minutes, which is equivalent to 3.33 hours. The course N72°E indicates that the boat is traveling 72° east of north. Using the formula d = v * t, where d represents the distance, v represents the velocity, and t represents the time, we can calculate the distance traveled in the first segment as 6 knots * 3.33 hours = 19.98 nautical miles.

In the second segment, the boat travels at a speed of 12 knots for a duration of 5 hours. The course S27°E indicates that the boat is traveling 27° east of south. Using the same formula, we calculate the distance traveled in the second segment as 12 knots * 5 hours = 60 nautical miles.

To find the total distance from the port, we can use vector addition. The boat's displacement in the north-south direction is 0 (since the boat changed from a northern course to a southern course), and the displacement in the east-west direction is the sum of the distances in each segment: 19.98 nautical miles + 60 nautical miles = 79.98 nautical miles.

Therefore, the boat is approximately 79.98 nautical miles from the port.

If the pennants have a base of 2 meters, the area of one of the larger pennants is 4m².

It is determined by multiplying the length of the rectangle by its width. The formula for area of a rectangle is Area = Length × Width (A = L × W).

To calculate this, we can use the formula for area of a rectangle which is length multiplied by width.

In this case, the length and width of the pennant is both 2 meters, so we can calculate the area by multiplying 2m * 2m= 4m².

The sports team asked Katie to make 30 larger pennants, so the total area of all the pennants will be 120m² (4m² * 30).

This means that the total area of the 30 larger pennants is 120m².

The formula for area of a rectangle can be used to calculate the area of any shape that is rectangular in nature.

Therefore, it can be used to calculate the area of a pennant, or any other shape that is rectangular in nature.

Answer:

x = 2.7

Step-by-step explanation:

From the question given above, the following data were obtained:

QM = angle bisector of angle PQR

Angle PQN = 7x + 15

Angle NQM = 4x

x =?

Since QM is the angular bisector, it means that it bisect PQR into two equal angle i.e 45° each.

See attachment for diagram.

Thus, we can obtain the value of x as follow:

7x + 15 + 4x + 45= 90° (angle in a right angle triangle)

7x + 4x + 15 + 45= 90

11x + 60 = 90

Collect like terms

11x = 90 – 60

11x = 30

Divide both side by 11

x = 30/11

x = 2.7

Therefore, the value of x is 2.7

Total number of games for 9 teams so that each team will play 12 games in the baseball league will be 432

Total number of teams in the baseball league is 9

Total number of games that each team will play is 12

Since, each team will have option of 8 teams to play with since no team can play with itself

Therefore, number of games that each team will play after playing 12 games will be 8 x 12 = 96

Since there are 9 teams, therefore total number of games that two teams will play = 96 x 9 = 864

Now, as it takes two teams to play a game therefore the required number of games for the 9 teams = 864/2 = 432

The wonderful waffle cone holds more ice cream than super sundae cone.

In this question,

The ice cream cone is the shape of hemisphere at the top and cone shape at the bottom.

Volume of ice cream cone = volume of hemisphere + volume of cone

Volume of ice cream cone = \(\frac{2}{3}\pi r^{3} +\frac{1}{3} \pi r^{2} h\)

Volume of super sundae cone:

Radius of hemisphere = height of hemisphere = 0.5 in

Depth of the ice cream cone = 4 in

Volume of super sundae cone = \(\frac{2}{3}\pi (0.5)^{3} +\frac{1}{3} \pi (0.5)^{2} (4)\)

⇒ \(\frac{2}{3}(3.14)(0.125) +\frac{1}{3} (3.14)(0.25)(4)\)

⇒ 0.2616+1.0466

⇒ 1.3082 ≈ 1.31 cubic in.

Volume of wonderful waffle cone:

Radius of hemisphere = height of hemisphere = 0.9 in

Depth of the ice cream cone = 3 in

Volume of wonderful waffle cone = \(\frac{2}{3}\pi (0.9)^{3} +\frac{1}{3} \pi (0.9)^{2} (3)\)

⇒ \(\frac{2}{3}(3.14)(0.729) +\frac{1}{3} (3.14)(0.81)(3)\)

⇒ 1.526+2.5434

⇒ 4.0694 ≈ 4.07 cubic in.

Thus volume of wonderful waffle cone > volume of super sundae cone.

On solving the equation Ý = 140 + (-0.0667)X, the value for blood pressure is obtained as 129.328 mm Hg.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

The equation is given as Ý = 140 + (-0.0667)X.

An amount of medication of 160 mg is found to result in a blood pressure of 127.74 mm Hg.

Here the value of X is X = 160.

The predicted blood pressure will be -

Ý = 140 + (-0.0667)160

Ý = 140 - 10.672

Ý = 129.328

The predicted blood pressure value is 129.328 mm Hg.

Here the predicted blood pressure value 129.328 mm Hg is greater than the actual blood pressure value 127.74 mm Hg.

Therefore, the observed value will be below the regression line.

2. When the statistics students number = 10·x + 3, we have;

The number of students that study

a. Algebra = 128/11

b. Statistic = 213/11

When the statistics students number = 2·x + 3, we have;

The number of students that study

a. Algebra = 16

b. Statistic = 15

Step-by-step explanation:

The parameters given are;

Total number of students = 30

Number of students that study algebra n(A) = x + 10

Number of students that study statistics n(B) = 10·x + 3

Number of student that study both algebra and statistics n(A∩B) = 4

Number of student that study only algebra n(A\B) = 2·x

Number of students that study neither algebra or statistics n(A∪B)' = 3

Therefore;

The number of students that study either algebra or statistics = n(A∪B)

From set theory we have;

n(A∪B) = n(A) + n(B) - n(A∩B)

n(A∪B) = 30 - 3 = 27

Therefore, we have;

n(A∪B) = x + 10 + 10·x + 3 - 4 = 27

11·x+13 = 27 + 4 = 31

11·x = 18

x = 18/11

The number of students that study

a. Algebra

n(A) = 18/11 + 10 = 128/11

b. Statistic

n(B) = 213/11

Hence, we have;

n(A - B) = n(A) - n(A∩B) = 128/11 - 4 = 84/11

Similarly, we have;

n(B - A) = n(B) - n(A∩B) = 213/11 - 4 = 169/11

However, assuming n(B) = (2·x + 3), we have;

n(A∪B) = n(A) + n(B) - n(A∩B)

n(A∪B) = 30 - 3 = 27

Therefore, we have;

n(A∪B) = x + 10 + 2·x + 3 - 4 = 27

2·x+3 + x + 10= 27 + 4 = 31

3·x = 18

x = 6

Therefore, the number of students that study

a. Algebra

n(A) = 16

b. Statistics

n(B) = 15

Hence, we have;

n(A - B) = n(A) - n(A∩B) = 16 - 4 = 12

Similarly, we have;

n(B - A) = n(B) - n(A∩B) = 15 - 4 = 11

Answer:  B) Rotation

Explanation:

The preimage has been rotated 180 degrees to land on the image.

Proof of this is to note that a point like (2,2) maps to (-2,-2)

The 180 degree rotation rule is \((x,y) \to (-x,-y)\). We flip the signs of each coordinate.

You can accomplish the same thing with two reflections: one over the x axis and the other over the y axis. However, a rotation is more direct.
