Answer:
96 people.
Step-by-step explanation:
Exponential equation for a decreasing amount:
The exponential equation for a decreasing amount is given by:
In which A(0) is the initial rate and r is the decay rate, as a decimal.
Currently, the number of people entering a shopping mall is 109.
This means that 
It is estimated that the number of people entering the shopping mall will decrease by 3% each hour.
This means that 
So
Find the total number of people entering the shopping mall at the end of 4 hours.
This is A(4). So
Rounding to the nearest whole number, 96 people.
The function which is not continuous is C. <span>number of tennis balls that can fit completely inside a particular box as a function of the radius of the tennis balls.
The reason for this is because the number of these balls is discreet, not continuous (meaning that there cannot be 6.5 balls).

The equivalent expression for the given expression (w+9)+3 using associative property is w + 12
<u>Solution:</u>
Given that, expression is ( w + 9 ) + 3
We have to find how do we can use the associative property to write an expression equivalent to ( w + 9 ) + 3
The associative property states that you can add or multiply regardless of how the numbers are grouped
By above definition, we get
(a + b) + c = a + (b + c)
So, now let us apply the above property to the given expression,
Then, ( w + 9 ) + 3 = w + ( 9 + 3 ) = w + 12
Hence, the equivalent expression for the given expression is w + 12
