A new shopping mall records 150 total shoppers on their first day of business. Each day after that, the number of shoppers is 15

Wewaii [24]

The number of shoppers is an illustration of an exponential function.

The expression for the number of shoppers is: $\mathbf{f(n) = 150(1.15)^n}$

The given parameters are:

$\mathbf{a = 150}$ -- the number of shoppers on the first day of business

$\mathbf{r = 15\%}$ --- the rate

Because, the number of shoppers increases each day, the number of shopper on a certain day is:

$\mathbf{f(n) = a \times (1 + r)^n}$

Substitute 15% for r

$\mathbf{f(n) = a \times (1 + 15\%)^n}$

Express percentage as decimal

$\mathbf{f(n) = a \times (1 + 0.15)^n}$

$\mathbf{f(n) = a \times (1.15)^n}$

Substitute 150 for a

$\mathbf{f(n) = 150 \times (1.15)^n}$

$\mathbf{f(n) = 150(1.15)^n}$

Hence, the expression for the number of shoppers is: $\mathbf{f(n) = 150(1.15)^n}$

What is the rule for the sum of angles?

Greeley [361]

Answer: Memorise the rule that the sum of the interior angles of a polygon = (n-2) × 180°, and that each interior angle of a regular polygon can be calculated by the rule: (n-2) × 180° / n, where 'n' refers to the number of sides.
