The midpoint of AB is M(4,0). If the coordinates of A are (3, -1), whatare the coordinates of B?
Answers
Answer:
Step-by-step explanation:
B (5,1)
Final answer:
By using the midpoint formula in reverse, we calculate the coordinates of point B to be (5, 1), given the midpoint M(4,0) and one endpoint A(3,-1).
Explanation:
In mathematics, the midpoint formula is commonly used to determine the middle point between two given points. The formula is M = [(x1+x2)/2 , (y1+y2)/2]. In this scenario, we are given the midpoint M(4,0) and one endpoint A(3,-1). We need to find the coordinates of the other endpoint, B. By using the midpoint formula in reverse, we can calculate for x2 and y2. Thus, the x-coordinate of B would be 2x - x1, so 2*4 -3 = 5. The y-coordinate of B would be 2y - y1, so 2*0 - (-1) = 1. Therefore, the coordinates of B are (5, 1).

Entonces, para esta ecuación, usaremos un porcentaje igual o superior a 100 como se indica aquí. ( =
) Entonces tu ecuación es
=
Multiplicará 28 por 100, lo que le dará 2800. Luego, dividiría 2800 entre 48, lo que le daría 58. Entonces, su respuesta sería x = 58%.

Answer:
0.7
Step-by-step explanation:
The probability that the number is in set A’ is the probability that a number is not in set A.
From the venn diagram attached below, they are two sets, set A and set B. Set A has 3 elements {15, 12 18}, Set B has 5 elements {12 18 10 14 16}.
The total number of elements in the universal set is 10 i.e {10 11 12 13 14 15 16 17 18 19}
therefore the number of elements in set A' is 7, i.e {10 11 13 14 16 17 19}.
the probability that the number is in set A’ = number of elements in set A'/number of elements in the universal set
probability that the number is in set A’ = 7 / 10 = 0.7

The dimension of the rectangular prism with different surface areas will be 2 cm by 4 cm by 9 cm. Then the correct option is B.
What is the volume of the rectangular prism?
Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as
V = L x W x H
The volume of the rectangular prism is 72 cubic cm.
Then the factor of the number 72 will be
72 = 2 x 2 x 2 x 3 x 3
Then the dimension of the rectangular prism will be
L x W x H = V
L x W x H = 72
L x W x H = 2 x 2 x 2 x 3 x 3
L x W x H = 2 x 4 x 9
The dimension of the rectangular prism with different surface areas will be 2 cm by 4 cm by 9 cm. Then the correct option is B.

volume of rectangular prism = (area* height )
so 2 * 4 * 9 = 72 cm3
9* 4 * 2 = 72 cm3
