Answer:
The approximate value of machine after 3 years = $12283
Step-by-step explanation:
Original cost of the copy machine = $20,000
Rate of depreciation each year = 15%
To, find cost of machine after 3 years.
Solution:
The depreciation equation can be given by:
where:
Final value
Original value
rate od depreciation in decimal form
time
Given values:
Using the values to find the value of machine after 3 years.
Thus, approximate value of machine after 3 years = $12283

Answer:
1.75
Step-by-step explanation:
7/4 = 1 with remainder of 3
30 / 4 = 7 with remainder of 2
20 / 4 = 5

a = 4.4 m/s^2 This is an acceleration and is positive.
vi = 10.2 m/s
t = 4.2 seconds
vf = ????? The cruising speed in this case is vf.
Formula
a = (vf - vi)/t Notice the 3 givens and what you seek determine the formula
Solve
4.4 m/s^2 = (vf - 10.2)/4.2 Multiply both sides by 4.2
4.4 * 4.2 = vf - 10.2
18.48 = vf - 10.2 Add 10.2 to both sides
18.48 + 10.2 = vf 8.28 is the second best answer.
28.68 = vf This is your cruising speed.
C <<<< Answer
First, you wrote -3x-7<20, that means -3x<20+7
or -3x<27 and we have x>-9
We draw the line of equation x= -9 and we have the set of solution is the haft of the plan on the right of the line x= -9
