Answer:
The domain represents the time of motion of the meteor as it falls from 100 km height above the Earth's surface at a speed of 20 km
Step-by-step explanation:
The given parameters from the question are;
The elevation of the meteor above the Earth's surface = 100 km
The rate at which the meteor falls = 20 km per second
The 'x' values represent the time in seconds and the 'y' values represent the meteor's height
Therefore, we have;
y = 100 - 20·x
The domain of a function is the set of inputs to the function
Therefore, the domain represent the time it takes the meteor to reach the given 100 km height above the Earth's surface
At the start x = 0 seconds
On the Earth's surface, y = 0, therefore;
0 = 100 - 20·x
x = 100/20 = 5
When the meteor just touches the Earth's surface x = 5 seconds
Therefore, the domain is 0 ≤ x ≤ 5.
The answer for this problem is 3.66666666.
Answer:
not unless its a negative integer
Step-by-step explanation:
380 is more than 248 but if 380 was put as a negative, it would be seenon the number line as less.
example: -380.......0........248
example 2: 0.....248.....380
Answer:
It should be 16.416 (round if needed)
Explanation:
You find this using tangent because the diagram prompts you to use the angle, the opposite side of the angle, and the adjacent side. Tan= opposite/ adjacent
So you use tan46=17/x
Get x by itself
x= 17/tan46
^^ you can plug that into a calculator
Hope this helps
