Answer:
When 324 belts have been produced, the average cost is changing at -28 dollars for each additional belt.
Step-by-step explanation:
The cost of producing x belts is given by:
Find the rate at which average cost is changing when 324 belts have been produced.
This is 
. So
So the correct answer is:
When 324 belts have been produced, the average cost is changing at -28 dollars for each additional belt.
Answer: 14.48000 . . . ≤ t < 15.0000
Step-by-step explanation:
"Truncated by a hundreths of a second" means that the time was rounded to the nearest 0.0X second. That would mean the reported time of 14.48 seconds was shortened from a time period having more digits to the right. For example, If the time were actually 14.48223 seconds, the time was truncated to just 14.48 seconds. The term used here. truncated, means that the digits after the hunredth place are simply dropped. It doesn't say rounded, just truncated. Brutal. So that would mean that times between 14.48000 . . . and 14.48999 . . . would all be reported as 14.48 seconds.
So the time could actually be 14.48000 . . . ≤ t < 15.0000
Answer:
Step-by-step explanation:
This is an arith. sequence.
The first term is 3 and the common difference is 1
Thus, the general formula for the nth term of this sequence is:
a(n) = 3 + 1(n - 1) This matches Answer A
