Which relation is a function?

Answers

Answer 1

Answer:

As given in the question,

the relations A , B ,C and D are set up as a table of ordered pairs.

We now test to see if each element in the domain(x-values) is matched with exactly one element in the range(y-values). If so, you have a function!

A is not a function as the domain value 0 is paired with both 3 and 4.

B is a function as for each input there is exactly one output.

C is not a function as the domain value 2 is paired with both 1 and 8.

A is not a function as the domain value 1 is paired with both -3 and 2.

Answers

parenthesis, exponents, multiplication, division, addition, subtraction.

(14)/(7)(5)(-3)^2 solve exponent first and then the multiplication part (7x5)

(14)/(35)(9) 14 divided by 35 is .4

(.4)(9)=3.6 .4 multiplied by 9 is 3.6 <- that's the answer for 7

remember parenthesis first so we will do 6-1 first which is 5. after parenthesis, well do exponents. 5^2 is 25.

we will finish the big parenthesis which is the brackets, and 30-25=5. now it's 5 +5=10<- that is the answer for 9. Do I need to explain more/ if not i hope this helps you better understand this.

Suppose you are given a bottle of water and three beakers. One of the beakers holds 30mL, one holds 40mL, and the largest of three beakers holds 200mL when full. There aren't any markings on any of the beakers. Describe how you could put exactly 20 mL of water in the large beaker without using any other equipment.

Answers

Fill the 200mL beaker all of the way. Using the water in that beaker, fill and pour out the 30mL twice and the 40mL three times. You should be left with 20mL in the 200mL beaker.

you can fill the 40 ml beaker, then empty it into the 30 ml beaker. you should be left with 10 ml in the beaker, pour this into the 200 ml beaker
repeat this and you should have 20 ml in the 200ml beaker
