Answer:
Shown in the picture
Step-by-step explanation:
A:
Set the value of x to "5" and "30" to find the corresponding values of y (i.e. the altitudes of the plane at 5 or 30 minutes after beginning descent).
B:
Use the the same method to determine the set of coordinates (/ordered pairs) at each of the values for x given in part B of the question.
C:
The initial value is simply the starting value of y, or in other words, the altitude at which the plane begins to descend in this context;
So it will be 0 mins after the beginning of descent of the plane, i.e. when x = 0, therefore the answer is (0, 28000) as an ordered pair or simply 28000 ft.
D:
Rate of change is a fancy or more technical way of referring to the gradient of a function;
In this case of the context of a plane descending, it refers to the change in altitude over time;
This can be calculated using any two ordered pairs (or coordinates as I call them) using the formula of the difference in the y values divided by the difference in the x values.
Answer:
5 cubic units
Step-by-step explanation:
If each cube represents 1 cubic unit, then the volume will be the number of cubes to make the figure. When you count, there are 5 cubic units. The volume is 5.

Step-by-step explanation:
If Sarah makes a profit of $ 4 on every necklace she sells, then:
4 necklaces = 4 * 4 = $ 16
6 necklaces = 6 * 4 = $ 24
8 necklaces = 8 * 4 = $ 32
10 necklaces = 10 * 4 = $ 40
<u>The correct table is A.</u>
To find the slope, use the simple rule rise/run. The change in the y value over the change in the x value. The y changes by -1 when the x changes by positive 2. Therefore, the slope is -1/2.
