Answer:
a) The unit rate of change of d with respect to t is equal to 1.6
b) the graph of the line in the attached figure.
1) Create a number line with that can fit all your numbers
-----|------|-------|-----|---
1 2 3 4
2) then put an x over the number that you have. If you have the number more than once put how many numbers there are Example: 1,2,3
x x x x x
---|--------|------|------- x x x
1 2 3 --------|-------|-------| <- For more than one of the same number 1 2 3 Example: 1,1,2,3,3
Answer:
(b) The planet's mass =10.241032 kilograms.
Step-by-step explanation:
Here, the mass of Neptune = 1024 1032 milligrams
Also, given: 1 milligram = 0.0000001 kilograms.
or, 1 milligram = 
kilograms.
Now, to convert 1024 1032 milligrams in to kilograms, we get:
1024 1032 milligrams = 
kilograms.
Now solving , we get:
kilograms.
Hence the planet's mass =10.241032 kilograms.
Area of the base of the model
3*2 = 6 square feet
Since the actual building 120 times bigger than the model, it should be multiplied with 120
6*120 = 720 square feet
