The domain of this graph is that x ≤ 2.
The domain of any function is the number that you can put in for x. Since the highest number possible for x is 2, this means x must always be 2 or lower. Therefore we can write it as x ≤ 2
Answer:
6)Staircase logic
Step-by-step explanation:
Answer:
x>1
Step-by-step explanation:
12x+2>14
12x>12
x>1
60/6000 = x/1423
100/1 = 1423/x
100x = 1423
x = 14.23 --> About 14 cm
Answer:
36 trees
Step-by-step explanation:
We are told that It takes four workers six hours and 45 minutes to plant 24 trees. Also that the time it takes to plant trees varies directly with the number of trees and inversely with the number of workers.
Thus,
t ∝ x/n
Where;
x is number of trees
n is number of workers
Now, opening the proportion symbol, we have;
t = kx/n
Where k is the constant of proportionality.
t = 6 hours 45 minutes = 6¾ hours = 6.75 hours
Plugging in the relevant values, we have;
6.75 = 24k/4
k = 4 × 6.75/24
k = 1.125
Now, we want to know how many trees could 9 workers plant in four and a half hours (4.5 hours)
Applying the same as above and Plugging in k = 1.125, we have;
4.5 = 1.125x/9
x = 9 × 4.5/1.125
x = 36 trees
