<span>The "product line" rule must be used to find out the number of ways that two representatives can be picked so that one is a mathematics major and the other is a computer science major.

The product line states that if the two functions f(x) and g(x) are differentiable (i.e. the derivative exist) then the product is differentiable and:
(fg)'=f'g+fg'
Answer: C. Sympathetic nervous system
Explanation: The sympathetic nervous system is a part of the involuntary or autonomic nervous system, this is the system in the body that regulates the blood pressure, body temperature, pupil dilation, sweating and all the involuntary actions. It helps adjust the body fast enough to take action or react to stimuli without consciousness. When in the face of danger, let say for example, a snake coming towards you, a car coming towards you or hearing disturbing sounds in the dark. You next action or respond will be either to stand and fight or run away, The system responsible for that action (fight or flight) is the sympathetic nervous system.
Answer:
a.Costs initially go down and then go up.
Explanation:
The average total cost curve of an enterprise consists of the sum of the fixed cost curve and the variable cost curve. Fixed costs are those that cannot be eliminated in the short term, such as the utility bill. Varied costs are those that can be reduced if the company decreases the quantity produced. For example, inputs and labor.
Thus, initially the total cost curve tends to decrease as production increases, as fixed costs are slowly diluted as the production process advances. However, at some point this cost curve tends to increase, because if there is no economy of scale, marginal production will be decreasing, ie, after a certain point of production, each additional production will be more expensive (will require more variable costs ) and this will lead to an inflection in the average cost curve, which will increase further.
Answer: Serotonin is likely in short supply
Explanation: serotonin is a neurotransmitter produced by nerve cells that is involved in depression, appetite, and is crucial in maintaining a sense of well-being, security, etc. It is called the happy chemical because of it involvement in making one happy. An imbalance influences the mood of an individual.
