Sagot :
a) point (8.28)
the time is 8 minutes
28 is the water level which is 28 cm
b) 3.5
the function for the situation is y=3.5x
the slope of the function is equal to the value of the unit rate
the time is 8 minutes
28 is the water level which is 28 cm
b) 3.5
the function for the situation is y=3.5x
the slope of the function is equal to the value of the unit rate
Answer:
See below ↓↓↓
Step-by-step explanation:
(a)
- The point (8, 28) represents the fact that in 8 minutes time, the water level of the horse trough is at 28 cm
(b)
- The unit rate will be equal to the slope of the graph
- y = 3.5x is given as the equation
- m = 3.5
- Therefore, rate is 3.5 cm/min
(c)
- On taking the slope of these two points it is equal to the slope of the line
- Therefore, we can say that the rise in water level directly varies with time
