Answer:
The range is 8.
Step-by-step explanation:
7, 1, 9, 3, 5
The range = Largest no. - Smallest no.
9 - 1 = 8
A.51
because 5x15=75, 8x3=24, 75-24=51
Answer/Step-by-step explanation:
a. Using two points on the line (0, 2) and (4, 12), find the gradient:
Gradient = ∆y/∆x = (12 - 2) / (4 - 0) = 10/4 = 2.5
Gradient = 2.5
b. The gradient, 2.5, represents the unit rate. That is, the volume of the oil in the tank per second.
i.e. 2.5 litres per second
c. The value, L = 2 represents the y-intercept, which is the starting value or initial volume of oil in the tank at 0 secs.
The first function is represented by the green line, while the second is represented by the orange line
<h3>What are piecewise functions?</h3>
Piecewise functions are functions that have at least 2 sub functions, each of which have different intervals
The function is defined by

<h3>(a) Graph the first function</h3>
The first function in f(x) is defined by

<h3>(b) Graph the second function</h3>
The second function in f(x) is defined by

See attachment for the graph of the second function
