metres
Step-by-step explanation:
Given: Length of board =
metres
Length of board was divided into two.
Length of one piece =
metres
Let
= length of the other board
Length of the other board = Length of board - Length of one piece
So, 

Thus, length of the other board
metres
Answer:
A linear function is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
An exponential equation is written as:
y = A*(r)^x
Where A is the initial quantity and r is the rate of growth.
If a and A are both positives, the similar characteristic of both types of functions is that as x increases, then the value of y will also increase. Then both functions are increasing functions.
They are different in how they increase, while a linear function increases at a constant rate, an exponential function increases slow at the beginning and really fast as x increases, as you can see in the image below where we compare the two types of functions, the green one is the linear function, and the blue one is the exponential function.
Answer:
No.
