I am not sure if I am correct.
I think that the angles did not help to solve the problem, ( it makes an obtuse angle)
and the unit rate is 421 mph and 384 mph.
2*421+384*2= 1610 miles
or
2 (421+384)= 1610 miles
Answer: 1610 miles
Answer: B, C, E

The difference between consecutive terms (numbers that come after each other) in arithmetic sequences is the same. That means you add the same number every time to get the next number. To figure out which choices are arithmetic sequences, just see if the differences are the same.
Choice A) 1, -2, 3, -4, 5, ...
-2 - 1 = -3
3 - (-2) = 5
The difference is not constant, so it is not an arithmetic sequence.
Choice B) 12,345, 12,346, 12,347, 12,348, 12,349, ...
12,346 - 12,345 = 1
12,347 - 12,346 = 1
The difference is constant, so it is an arithmetic sequence.
Choice C) <span>154, 171, 188, 205, 222, ...
171 - 154 = 17
188 - 171 = 17
The difference is constant, so it is an arithmetic sequence.
Choice D) </span><span>1, 8, 16, 24, 32, ...
8 - 1 = 7
16 - 8 = 8
</span>The difference is not constant, so it is not an arithmetic sequence.
Choice E) <span>-3, -10, -17, -24, -31, ...
-10 - (-3) = -7
-17 - (-10) = -7
</span>The difference is constant, so it is an arithmetic sequence.
I think it's 0 since anything multiplied by 0 is, well, 0! No matter what the sign is. I believe the correct answer is 0 :)

Una pregunta, ¿estudias en educazion.net?
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.
