When you substitute 0 for the exponent x, the expression simplifies to a times 1, which is just a. This is because any number to the 0 power equals 1. Since the initial value is the value of the function for an input of 0, the initial value for any function of this form will always be the value of a.

Step-by-step explanation:
The value of the linear correlation coefficient, r, as calculated using Microsoft excel is: 0.708,
The linear correlation coefficient, r, using Excel spreadsheet
Step1: Open Microsoft excel spreadsheet
Step2: Entre the cost of advertising on one column, and the number of products sold on another column.
Step3: Select a blank cell and input the formula: =CORREL(B3:B10, C3:C10)
Step4: Press "entre" to get the value of the linear correlation coefficient.
Therefore, the value of the linear correlation coefficient, r, as calculated using Microsoft excel is 0.708.

Answer:
We are calculating the Hypotenuse of a right triangle.
Step-by-step explanation:
Distance Formula: When working on a coordinate plane, you can always find the distance between two points (or the length of a line segment) by creating a right triangle and using the Pythagorean Theorem. Draw a right triangle such that the distance between the two points is the hypotenuse.
Hence, When you use the distance formula, you are calculating the length of the Hypotenuse of a right triangle.
