The graph is a function because when you use the vertical line test it does not hit more than one point at any given place on the line.
Hope this helped :)
Answer:
2. 13
Step-by-step explanation:
The least number of classes need for all of the students to be registered in a class is 13 since you want all of the stuednts to be registered so no one should be left out. If we do 12*12 (12 students in each class and there are 12 classes), that would only let 144 students take the swimming classes and 8 students would be left out. We don't want that though since we want all of the students to be registered. So let's go to 12*13 (12 students in each class and there are 13 classes), that would let 156 students take the swimming class. 156>152 so therefore, 13 classes would allow for all 152 students to be registered and it is the least number of classes needed for all the students to be registered in a class (plus you would have 4 seats left for anyone who wants to register in the future but the remainder doesn't matter).
the answer is 3648 quarts
Answer:
Over a 22 seconds, the altitude will be: 924 feet
Step-by-step explanation:
- Let 'x' be the time in seconds
As the altitude of an airplane is decreasing at a rate of 42 ft per second.
Thus, the expression to find the altitude at x seconds is:
y = 42x
so at x = 1 sec, y = 42 feet
Now, putting x = 22 seconds to determine the altitude at 22 seconds
y = 42x
= 42(22)
= 924 feet
Thus, over a 22 seconds, the altitude will be: 924 feet
Answer: store 1 f(X)= 70+2.50X Store 2 f(x) 60+5x
Step-by-step explanation: So i gave you the equations because i don't really understand the what its asking me for and the lower price is store 1
