It is not possible to guarantee the exact number of points within a certain distance of each other in a square with 42 points placed inside.

Since the side length of the square is 2, the area of the square is 2 x 2 = 4. If 42 points are placed inside the square, the maximum distance between any two points will be equal to the diagonal of the square, which is equal to the square root of 2 times the side length of the square. The diagonal of the square is 2 * √(2), or approximately 2.82.

The number of points within a certain distance of each other depends on the size of the distance, as well as the density of the points in the square. However, it is not possible to guarantee that all 42 points will be within a certain distance of each other. The best we can say is that most of the points will be relatively close to each other, but some may be farther apart. The exact number of points that are within a certain distance of each other will depend on the specific arrangement of the points.

It took 245.33 watts of power to perform the work.

What is the work?

Work is defined as a force causing the movement or displacement of an object. In the case of a constant force, work is the scalar product of the force acting on an object and the displacement caused by that force.

The work done by Mr. Muscles can be calculated as follows:

Work = Force x Distance x Cos(θ)

where Force is 910 N, Distance is 4 m (since he lifts the weight 0.5 m 8 times), and θ is the angle between the force applied and the displacement of the weight, which is assumed to be 0° in this case since the weight is being lifted straight up.

Work = 910 N * 4 m * cos(0°) = 3640 N * m

The power required to perform this work in 15 seconds can be calculated as follows:

Power = Work / Time

Power = 3640 N * m / 15 s = 245.33 W

hence, it took 245.33 watts of power to perform the work.

The triangle with the greater perimeter has angles 55, 15, and 112 degrees.

In a triangle, the sum of the interior angles is 180 degrees. Thus, if we have two non-congruent triangles with one angle equal (in this case, B = 55 degrees), we can set up an equation to solve for the third angle of the triangle with the greater perimeter.

Let's call the third angle in the first triangle x. Then, x + 55 + b = 180 degrees, or x + b = 125 degrees.

Since we know that a + b + B = 180 degrees for any triangle, we can set up a similar equation for the second triangle: y + 55 + a = 180 degrees, or y + a = 125 degrees.

Since the perimeter of a triangle is equal to the sum of its side lengths, and we know that a = 15 and b = 13, we can set up another equation to find the triangle with the greater perimeter:

Perimeter 1 = 15 + 13 + x and Perimeter 2 = 15 + 13 + y.

Solving for x, we find that x = 125 - b = 125 - 13 = 112 degrees. Solving for y, we find that y = 125 - a = 125 - 15 = 110 degrees.

Since 112 > 110, the triangle with the greater perimeter has angles 55, 15, and 112 degrees.

The triangle with the greater perimeter is the one with the greater value of c, which we can calculate using the law of cosines and the law of sines.

Given two noncongruent triangles with angle B equal to 55 degrees and sides a and b, we need to find the measures of the angles of the triangle with the greater perimeter.

First, let's use the law of cosines to find the measure of angle A in each triangle:

[tex]c^2 = a^2 + b^2 - 2ab * cos(A)\\\\c = \sqrt{(a^2 + b^2 - 2ab * cos(A))} \\\\cos(A) = (a^2 + b^2 - c^2) / 2ab[/tex]

For the first triangle, we can use the given values:

[tex]cos(A) = (15^2 + 13^2 - c^2) / 2 * 15 * 13\\\\c = \sqrt{(15^2 + 13^2 - 2 * 15 * 13 * cos(A))}[/tex]

For the second triangle, we can use a and b as the lengths of the sides opposite angles A and C, respectively. Then we can use the law of sines to find the lengths of the other sides:

[tex]sin(A) / a = sin(C) / c\\\\c = a * sin(C) / sin(A)[/tex]

Substituting values and solving, we get:

[tex]c = 15 * sin(C) / sin(A)\\\\cos(A) = (15^2 + b^2 - c^2) / 2 * 15 * b\\\\c = \sqrt{(15^2 + b^2 - 2 * 15 * b * cos(A))}[/tex]

Now we can compare the two perimeters (the sum of the lengths of all sides) to determine which triangle has the greater perimeter. The perimeter of each triangle will be a + b + c.

Whichever triangle has the larger value of c will have the greater perimeter, as a and b are the same in both triangles.

So, we can use the value of c that we just calculated for each triangle to determine which triangle has the greater perimeter, and therefore, which triangle has the greater measure of its angles.

Here we have the triangles ΔABC and ΔCDE. We know DC is equal to BC because they are marked as such, same for AC and EC. We also know <ACB = <DCE because they are vertically opposite angles. Since we have two triangles with equal sides and the same angle between these sides (SAS), we can say these triangles are congruent.

What is probability?

Probability is a mathematical concept that measures the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

(a) Given 3 balls were chosen at random without replacement, the probability that they were all green is given by:

P(green) = (number of favorable outcomes) / (number of total outcomes)

The number of favorable outcomes is the number of ways to choose 3 green balls out of 4, which is C(4,3) = 4.

The number of total outcomes is the number of ways to choose 3 balls out of 9, which is C(9,3) = 84.

So, the probability that 3 balls chosen were all green is:

P(green) = C(4,3) / C(9,3) = 4 / 84 = 1/21

(b) The probability that all the balls chosen are red is given by:

P(red) = (number of favorable outcomes) / (number of total outcomes)

The number of favorable outcomes is the number of ways to choose 5 red balls out of 5, which is C(5,5) = 1.

The number of total outcomes is the number of ways to choose 5 balls out of 9, which is C(9,5) = 126.

So, the probability that all the balls chosen are red is:

P(red) = C(5,5) / C(9,5) = 1 / 126 = 1/252

The expression tan(t)sin(t)/cot(t) is negative.

What is the quadrant?

A quadrant is one of the four regions into which the plane is divided by the x-axis and y-axis. There are four quadrants in total:

First quadrant (Quadrant I): The values of x and y are both positive.

Second quadrant (Quadrant II): The value of x is negative, and the value of y is positive.

Third quadrant (Quadrant III): Both the values of x and y are negative.

Fourth quadrant (Quadrant IV): The value of x is positive, and the value of y is negative.

The location of a point in a plane can be determined by its coordinates (x, y), and based on the sign of x and y, the point can be located in one of the four quadrants.

The given expression is tan(t)sin(t)/cot(t).

If the terminal point determined by t is in quadrant III (180° < t < 270°), then tan(t) and sin(t) are negative, and cot(t) is positive. In this case, the expression tan(t)sin(t)/cot(t) is negative.

Hence, the expression tan(t)sin(t)/cot(t) is negative.
