For the relations in this problem, we have that:
1.
The relation is not a function.The domain is {10, 11}.The range is {20, 30, 50}.2.
Domain: [-2, 0).Range: [0, 2).The relation is a function.3.
Domain: [-2, 2].Range: [-2,2].The relation is not a function.When does a relation represents a function?A relation represents a function if each value of the input is mapped to only one value of the output.
For a point in the format (x,y), we have that:
x is the input.y is the output.The meaning is that the input x is mapped to the output y.When does a relation graphed represents a function?A graph represents a function if it has no vertically aligned points, that is, each value of x is mapped to only one value of y.
What are the domain and the range of a function?The domain of a function is the set that contains all the values of the input of the function.The range of a function is the set that contains all the values of the output of the function.In a graph, the domain and the range are found as follows:
The domain is given by the values of x, present in the horizontal axis of the graph.The range is given by the values of y, present in the vertical axis of the graph.For the first relation, we have that input 10 is mapped to outputs 20 and 50, hence:
The relation is not a function.The domain is {10, 11}.The range is {20, 30, 50}.For the second relation, we have a graph with no vertically aligned points, hence:
Domain: [-2, 0).Range: [0, 2).The relation is a function.For the third relation, we have a graph with vertically aligned points, hence:
Domain: [-2, 2].Range: [-2,2].The relation is not a function.More can be learned about relations and functions at https://brainly.com/question/12463448

During one month Andre used 785 gallons of water at his home. There are approximately 3.8 liters in 1 gallon.Which measurement is closest to the number of liters Andre used during this month?
Answers
The closest measurement to the number of liters Andre used during the month is 2,983 liters of water.
How is the measurement determined?The measurement of the number of liters used is determined by multiplying the number of gallons of water by the approximate value of 1 gallon in liters.
Using one of the mathematical operations, multiplication, the conversion of the quantity of water from gallons to liters can be computed.
Data and Calculations:The total number of gallons of water used = 785
Conversion of 1 gallon to liters = 3.8 liters per gallon
The total number of liters of water used = 2,983 (785 x 3.8)
Thus, the closest measurement to the number of liters Andre used during the month is 2,983 liters of water.

Solve each equation. If necessary, round to the nearest ten-thousandth. log x²=2
Answers
The solution of the given equation by rounding off it to the nearest ten-thousandth is 2.7182.
What is a round-off of the digit?
In mathematics, a round-off is defined as an approximation of the given number to a fewer number of significant digits by taking into consideration some rules.
For eg: 13.58 ~ 13.6
Solving the given equation: log x² = 2
We are given a logarithmic expression: log x² = 2 —- 1
We know that log x² = 2 log x and log (ab) = log a + log b
Using in equation 1, we have,
2 log x = 2
log x = 1
Using exponential on both sides, we have
e^(log x) = e^1
x = e
x = 2.7182
Hence, the solution of the given equation rounded off to the nearest ten-thousandth is 2.7182.

Since the cookie sheets can hold exactly 1 dozen cookies, bbcc will produce and sell cookies by the dozen. How much time will it take to fill an order of 2, 3, or 4 dozen cookies?
Answers
Time taken to fill an order of 2, 3, 4 dozen cookies are 45 minutes, 64 minutes and 89 minutes respectively.
To calculate time taken to fill the orders, we will add time used in different processes separately.
time taken to spoon =2 min for each dozen
time taken to bake = 10 min for each dozen
time taken to cool = 5 min for each dozen
time taken to pack = 2 min for each dozen
time taken to receive payment = 1 min for each dozen
time for cookies = mins to mix + mins to spoon + total baking mins + mins to cool + mins to pack + min to receive payment
putting the values in the above formula, we get
Cycle time for 2 dozen cookies = 6 mins to mix + 4 mins to spoon + 20 total baking mins + 10 mins to cool + 4 mins to pack + 1 min to receive payment = 45 mins
Cycle time for 3 dozen cookies = 6 mins to mix + 6 mins to spoon + 30 total baking mins + 15 mins to cool + 6 mins to pack + 1 min to receive payment = 64 mins
Cycle time for 4 dozen cookies = 12 mins to mix + 8 mins to spoon + 40 total baking mins + 20 mins to cool + 8 mins to pack + 1 min to receive payment = 89 mins
Therefore, Time taken to fill an order of 2, 3, 4 dozen cookies are 45 minutes, 64 minutes and 89 minutes respectively.

The statement that the sales tax on a good that has been purchased is a function of the selling price in a given state, is TRUE.
How does sales tax relate to the selling price?The sales tax on an item that is purchased is calculated on the selling price of the item and then added to the item so that the person purchasing the item can pay for the sales tax as well.
Because the sales tax is based on the selling price, it is therefore a function of the selling price with the given state being the percentage of the sales tax.
For instance, a 4% sales tax on a good that is $10 is:
