1. The domain of Products Manufactured would be counting numbers. The best choice here might be ...
  4) whole numbers

The Cost of Production can have any positive value (not always limited to only 2 decimal places), so its range is likely best described by ...
  2) positive real numbers


2. The independent variable of the described function is "the number of observed vehicles in a specified time interval." If we assume only whole numbers of vehicles are observed, then the best choice for the domain appears to be the open-ended set of non-negative values ...
  4) {0, 1, 2, 3, ...}

Since we don't know what the function C does, except that it produces something called "the rate of traffic through an intersection", we really can't say what its range might be. The choice that allows the most possiblities* is the open-ended set ...
  1) {..., -2, -1, 0, 1, 2, 3, ...}

_____
* you might argue that traffic flow is always positive. I woud say that depends on your reference direction, and that it might be positive for part of the day and negative for another part. The choices here seem to include some of limited range. Whether that applies depends on the details of C(n), which we are not told. I would argue that C(n) might have a range that includes real numbers (limited only by the number of cars that can go through an intersection in a time period of interest--which might be quite large).

The first term of a sequence is -12. The recursive formula for the sequence is an = an-1 + 9. What are the next 3 terms in the s
Bess [88]
The next three terms are: -3, 6, and 15

To get each new term, we simply add 9 to the last term. So we add 9 to -12 to get -3. Then we add 9 to -3 to get 6. Finally we add 9 to 6 to get 15

In other words,
first term = -12
second term = first term+9 = -12+9 = -3
third term = second term + 9 = -3+9 = 6
fourth term = third term + 9 = 6+9 = 15

This process repeats forever though we only need three terms in this case.

So that's why the answer is the three values -3, 6 and 15

Given: ΔABC; b= 10; c = 14, and ∠A = 54°. Find the length of side a to the nearest whole number.
algol13
We can solve for the length of side a to the nearest whole number using the Laws of Cosines such as the formula is shown below:
a²=b²+c²-2bcCosA
Solving for the value of a, we have:
a²=10²+14²-2(10)(14)cos54°
a²=131.42
a=11.46
The answer is 11.46 or 11.5.
