The arithmetic mean of a set of numbers is found by adding up all the numbers in the set and then dividing the sum by the total number of numbers. In this case, the set of numbers is 2, 4, 7, 9, 13. Adding up these numbers gives us a sum of 35. Since there are 5 numbers in the set, we divide the sum by 5 to find the arithmetic mean. Therefore, the arithmetic mean of the given set of numbers is 7.

The given sequence is an arithmetic progression with a common difference of 5. The first term is 8, the second term is 13, and the third term is x-2. To find the value of x, we can use the formula for the nth term of an arithmetic progression: an = a1 + (n-1)d, where an is the nth term, a1 is the first term, n is the position of the term, and d is the common difference. Plugging in the values, we have x-2 = 8 + (3-1)5. Simplifying the equation, we get x-2 = 8 + 10, which gives x = 20.

The point C is the midpoint of the line segment AB. To find the coordinates of the midpoint, we take the average of the x-coordinates and the average of the y-coordinates of points A and B. The x-coordinate of point C is (-1+1)/2 = 0. The y-coordinate of point C is (2+4)/2 = 3. Therefore, the ordinate of point C is 3.

The given arithmetic progression has a common difference of 3 and a first term of 2. To find the limit of the progression, we can use the formula for the nth term of an arithmetic progression: an = a1 + (n-1)d, where an is the nth term, a1 is the first term, n is the number of terms, and d is the common difference.

Plugging in the values, we have a limit of a1 + (n-1)d = 2 + (n-1)3 = 3n - 1. Since we are looking for the limit, we set n to infinity. Therefore, the limit of the progression is 3(infinity) - 1, which is infinity.

Therefore, the correct answer is 29, as it is the only option that represents infinity.

The equation x^2 + y^2 = 9 represents a circle with a radius of 3 units centered at the origin. The point (0,3) lies on this circle because when we substitute x=0 and y=3 into the equation, we get 0^2 + 3^2 = 9, which is true. Therefore, (0,3) is a valid solution to the equation and represents a point on the circle.

The probability of an event occurring is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. In this case, the event is the sum of the two numbers being less than or equal to 4. There are 6 possible outcomes when two dice are rolled (1,1), (1,2), (1,3), (2,1), (2,2), (3,1). Out of these 6 outcomes, only one outcome has a sum greater than 4, which is (3,1). Therefore, the probability of the sum being less than or equal to 4 is 5/6 or 1/6.

The given equation of the line represents a straight line in the form of Ax + By + C = 0. Here, A = 2, B = -3, and C = 6. To find the x-coordinate of the point where the line intersects the x-axis, we set y = 0 in the equation and solve for x. Plugging in y = 0, we get 2x + 6 = 0, which simplifies to x = -3. Therefore, the line intersects the x-axis at the point (-3, 0), and the x-coordinate of this point is -3.

There are a total of 10 different groups of three that can be formed from five different books. This can be calculated using the combination formula, which is nCr = n! / (r!(n-r)!), where n is the total number of items and r is the number of items to be selected. In this case, n = 5 and r = 3, so the calculation is 5! / (3!(5-3)!) = 5! / (3!2!) = (5x4x3x2x1) / (3x2x1x2x1) = 10. Therefore, there are 10 different groups of three that can be formed.

8cm

The height of the cone is given as 6cm and the slant height is given as 10cm. To find the radius of the base, we can use the Pythagorean theorem. The slant height is the hypotenuse of a right triangle, with the height as one side and the radius as the other side. So, we can set up the equation as follows: (radius)^2 + (height)^2 = (slant height)^2. Plugging in the given values, we get (radius)^2 + 6^2 = 10^2. Simplifying the equation, we get (radius)^2 + 36 = 100. Subtracting 36 from both sides, we get (radius)^2 = 64. Taking the square root of both sides, we get radius = 8. Therefore, the radius of the cone is 8cm.

Explanation

The height of the cone is given as 6cm and the slant height is given as 10cm. To find the radius of the base, we can use the Pythagorean theorem. The slant height is the hypotenuse of a right triangle, with the height as one side and the radius as the other side. So, we can set up the equation as follows: (radius)^2 + (height)^2 = (slant height)^2. Plugging in the given values, we get (radius)^2 + 6^2 = 10^2. Simplifying the equation, we get (radius)^2 + 36 = 100. Subtracting 36 from both sides, we get (radius)^2 = 64. Taking the square root of both sides, we get radius = 8. Therefore, the radius of the cone is 8cm.

49. Pikat A(1,0), B(2,0) dhe C(3, 0) janë pikat e një :

parabole

rrethi

drejtëze

hiperbole

The given points A(1,0), B(2,0), and C(3,0) form a straight line on the x-axis. Since a circle is defined as a set of points equidistant from a center point, and these points do not meet that criteria, the correct answer is not a circle. Therefore, the correct answer is not a parabola, hyperbola, or circle. The only remaining option is a straight line, so the correct answer is a straight line.

2cos2x

2sinxcosx

The derivative of the function y = sin2x can be found using the chain rule. First, we differentiate the outer function sin2x with respect to the inner function 2x, which gives us cos(2x). Then, we multiply this by the derivative of the inner function 2x with respect to x, which is 2. Therefore, the derivative of y = sin2x is 2cos(2x). The correct answer is 2cos(2x).
