We are given, cost of the robot for 0 number of year = $16,000.
0 represents initial time of the robot.
After 10 year cost of the robot is = $0
The problem is about the number of the years and cost of the robot over different number of years.
So, we could take x coordinate by number of hours and y coordinate for y number of hours.
So, from the problem, we could make two coordinates for the given situation.
(x1,y1) = (0, 16000) and (x2,y2) = (10, 0).
In order to find the function of time, we need to find the rate at which robot rate depreciates each year.
Slope is the rate of change.
So, we need to find the slope of the two coordinates we wrote above.
We know, slope formula
Plugging values in formula, we get
Brecasue of depreciation we got a negative number for slope or rate of change.
Therefore, rate of depreciation is $1600 per year.
We already given inital cost, that is $16,000.
So, we can setup an a function
f(x) = -1600x + 16000.
But the problem is asked to take the variable t for time.
Replacing x by t, we get
f(t) = -1600t + 16000.
Answer:
ANSWER C
Step-by-step explanation:
y = x²
y = -x² reflect across the x axis
y = -(x + 2)² shift 2 units to the left
y = -(x + 2)² + 5 shift up 5 units

Step-by-step explanation:
Given the following question:
In order to convert a mixed number into an improper fraction we have to divide the numerator (in this case; 22) by the denominator (in this case; 6) to find your answer.
Let three represent how many times 3 goes into 11, let 2 represent the remainder while of course keeping the denominator the same. Your answer is "3 2/3."
Hope this helps.
