Answer:
Breaking up the multiplicand 8 into (5+3) allows us to apply the associative property of multiplication. See below.
Step-by-step explanation:
5*7 = 35. We want the product 8*7. Note that 8 = 5+3. Thus, 8*7=(5+3)(7) = 35 + 21, or 56.
The domain of the function can be represented using set-builder notation as follows: {x | x is a positive integer}. The range of the function can be represented using inequality notation as follows: 0 ≤ y ≤ 100.
<h3>What are the domain and range of the function?</h3>
The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.
Part A:
Hours Cost
1 10
3 30
11 100
20 100
Part B:
The domain of the function that represents the cost of renting a bicycle is the set of all possible values of the number of hours the bicycle is rented for. In this case, the domain is the set of all positive integers, because the bicycles must be returned the same day they are rented.
The range of the function is the set of all possible values of the cost of renting the bicycle. In this case, the range is the set of all non-negative numbers less than or equal to 100, because the maximum daily fee is $100.
Part C:
The domain of the function can be represented using set-builder notation as follows:
{x | x is a positive integer}
The range of the function can be represented using inequality notation as follows:
0 ≤ y ≤ 100

Determine the arrival time
First, we calculate the time taken from Belfast to Dublin using:
Substitute values to the expression.
Cross Multiply
Arrival time is then calculated as:
