Answer:
2
Step-by-step explanation:
Data provided in the question
Domain Range
x f(x)
2 4
-3 0
-1 -1
4 3
As we know that
x = f(x)
So for domains, the ranges are as follows
f(2) = 4
f(-3) = 0
f(-1) = -1
f(4) = 3
As we can see that when f(4) is there so the value of x = 2
The number of rounds of bingo when the two costs would be the same is 3.
<h3>When would the two costs be the same?</h3>
The equation that represents the total cost for adults is : 13 +2r
The equation that represents the total cost for children: 10 + 3r
where r is the number of rounds
When the two costs are the same, the two above equations would be equal: 13 + 2r = 10 + 3r
13 - 10 = 3r - 2r
r = 3

Thus, the height of the tree is
Answer:
A.
Step-by-step explanation:
48.
The values are greater than 2 and less than OR equal to 6. Thus there will be an open circle on x = 2 and a filled circle on x = 6. Also there will be a dark line between these 2 points. It's choice A.
Answer:
r <= 12.6
Step-by-step explanation:
Let's calculate the rate at which he descends:
r = (46.7 - 15.2)/212 = 0.15 feet/minute
