Answer: When you square each side of an equation then the resulting equation is not equivalent to the original

Answer 2

Answer: Yes, that is true.

If x = y, x² = y².
If x = y, substitute x into where y is;

x² = y²
x² = (x)²
Thus, yes they will be.

Show the work for 2 divided by 50

Answers

first you would do this write out 50 divided by 2 as an equation and put how many times does 2 go into 5 and 2 goes into 5 two times so you put two over the 5 on top of the division house and do that number multiplied by the number your dividing by which is 2 and hat equals 4 so do 5 minus 4 and that equals 1 bring the zero thats beside the 50 down and make the number 1 a 10 and see how many times 2 goes into 10 and that is 5 so you put the five on top of the division house then do five times 2 and that equals 10 down and do 10 minus 10 which equals 00 and then your done your answer should be 25

Given the triangle below, which of the following equations correctly representsthe relationship between a, b, and c?Triangle not drawn to scale A cz B az 2abcos (90.)b a2 c2 2abcos (90.)

Answers

The equation that correctly represents the relationship between a, b, and c in the triangle is c² = a² + b² - 2ab * cos(90)

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Cosine rule is used to show the relationship between the sides and angles of a triangle. It is given by:

c² = a² + b² - 2ab*cosC

Where a, b and c are the sides, while C is the angle opposite to side c.

In the triangle ABC, C = 90°, hence:

c² = a² + b² - 2ab * cos(90)

The equation that correctly represents the relationship between a, b, and c in the triangle is c² = a² + b² - 2ab * cos(90)

Find the probability that the number is in set A’ giving your answer as a decimal

Answers

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
