Answer:
The average rate of change is 4
Step-by-step explanation:
To find the values of y when x = 0 and when x = 2, we can graph the equation using a graphing calculator.
Looking at the graph, we can see that when x = 0 y = 5 and when x = 2 y = 13
Now that we have two points (0,5) and (2,13) we can find the rate of change
To find the rate of change we use this equation: 
Let's input the values from our two points
Simplify: 
= 4
5m-14/(m+1)(m-1)
excluded values: 1,-1
Answer:
Bob = 6km/h, Joe = 4km/h
Step-by-step explanation:
Bob walked 6km/h after 3 hours = 18 km
Joe walked 4km/h after 3 hours = 12 km
Finally, their distance is 30 km.
Answer:
Step-by-step explanation:
3.14159 is irrational because it's a repeating decimal; it cannot be expressed as the ratio of two integers. All the others can be expressed in that way.
The domain and range of the given function are equal to (0, 3.85) and (0, 18.75) respectively.
<h3>How to calculate the domain of the function?</h3>
In this exercise, you're given the following function h(t) = -4.87t² + 18.75t. Next, we would equate the function to zero (0) to determine its domain as follows:
0= -4.87t² + 18.75t.
4.87t(-t + 3.85) = 0
t = 0 or t = 3.85.
Therefore, the domain is 0 ≤ t ≤ 3.85 or (0, 3.85).
<h3>How to calculate the range of the function?</h3>
h(t) = -4.87t² + 18.75t
h(t) = -4.87(t² - 3.85t + 3.85 - 3.85)
h(t) = -4.87(t - 1.925)² + 18.05
Therefore, the range is 0 ≤ h ≤ 18.05 or (0, 18.75).
