Answer:

See below

Step-by-step explanation:

a. Since they tell you the amount of water increases 1/4 gallon in 2/5 minutes, you can also see that you'd have 2/4 gallons in 4/5 minutes. Then 3/4 gallons in 6/5 minutes; 4/4 or 1 gallon in 8/5 minutes. Finally you can go one more step and see that you would have 5/4 gallons or 1 1/4 gallons in 10/5 minutes.

10/5 minutes is equal to 2 minutes. so if you divide the gallons by 2 you'll know how many gallons you'd have in 1 minute. 5/4 divided by 2 is equal to 5/8 gallons.

Another way you can look at this is if you have 1/4 gallon in 2/5 of a minute, then you would only have half of the 1/4 gallon in 1/5 of a minute. Half of 1/4 gallon is equal to 1/8 of a gallon. So if you are getting 1/8 gallon in 1/5 of a minute, you can multiply them both by 5 to get your answer in gallons/minute.

5 times 1/8 is 5/8 and 5 times 1/5 minutes is 5/5 minutes or 1 minute.

So you get the same answer 5/8 gallons/minute

b. Above you calculated how many gallons you will get in 1 minute. So to figure out how much you will get in 5 minutes, you'd multiply 5/8 by 5. This gives you 25/8 or 3 1/8 gallons. If you started with 6 gallons in the tub, now you just add those two numbers together to get 9 1/8 gallons.

c. Again we can look at the sink the same as the bath tub. Keep adding the gallons and minutes until you can get the minutes fraction equal to a whole number. 3/5 gallon in 4/5 minutes double to be 6/5 gallons in 8/5 minute, 9/5 gallons in 12/5 minutes, 12/5 gallons in 16/5 minutes and finally 15/5 gallons in 20/5 minutes. 20/5 minutes is the same as 4 minutes in whole numbers.

So if you divide both the gallons and minutes by 4, you'll get how many gallons you're getting in 1 minute. 15/5 gallons divided by 4 is 15/20 gallons. This can be reduced down to 3/4 gallons. When you divide 4 minutes by 4, you get 1 minute. So the sink is getting 3/4 gallon/minute.

Which is getting more water per minute? 3/4 gallons/minute is more than 5/8 gallons/minute so the sink is filling more rapidly.

Answer:

Reminder that is this form a(b)^x where a > 0

When b > 0 but < 1 that is a decay function

When b > 1 than its a growth function

Step-by-step explanation:

So following this you can figure out the answer

g(x)=0.3(x)

this is neither since there is no exponent (linear)

H=72(56)^t

this is growth since b = 56

A=(43)^t

this is growth since b = 43 ("a" is understood as "1")

H=5.9(0.82)^t

this is decay since b = 0.82

y=0.8(3.6)^t

this is growth since b = 3.6

f(t)=0.72(15)^t

this is growth since b = 14

A=49(8)^t

this is growth since b = 8

Each answer choice below represents a relation by a set of ordered pairs. In which of the answer choices is the relation a funct

alexdok [17]

Answer:

A - Not Function

B - Function

C - Function

D - Not Function

E - Function

Step-by-step explanation:

For a relation to be a function, each value of input should have exactly one output. Which means that for one value of x, there should only one value of y. If the relation has repetition of x in its ordered pairs, it means that for one value of x, there are two or more values of y, hence the relation is not a function

(Consult the diagram below)

As x = 6 is being repeat, it means that x=6 has two values of y that are 12 and 4. IT IS NOT A FUNCTION.

No repetition of x, IT IS A FUNCTION.

No repetition of x, IT IS A FUNCTION.

As x = -1 is being repeat, it means that x=-1 has two values of y that are 4 and -2. IT IS NOT A FUNCTION.

No repetition of x, IT IS A FUNCTION.
