Answer:
Value of x maximising profit : x = 5
Explanation:
Cost : C(x) = x^3 - 6x^2 + 13x + 15 ; Revenue: R(x) = 28x
Profit : Revenue - Cost = R(x) - C(x)
28x - [x^3 - 6x^2 + 13x + 15] = 28x - x^3 + 6x^2 - 13x - 15
= - x^3 + 6x^2 + 15x - 15
To find value of 'x' that maximises total profit , we differentiate total profit function with respect to x & find that x value.
dTP/dx = - 3x^2 + 12x + 15 = 0 ► 3x^2 - 12x - 15 = 0
3x^2 + 3x - 15x - 15 = 0 ► 3x (x +1) - 15 (x + 1) = 0 ► (x+1) (3x-15) = 0
x + 1 = 0 ∴ x = -1 [Rejected, production quantity cant be negative] ;
3x - 15 = 0 ∴ 3x = 15 ∴ x = 15/3 = 5
Double derivate : d^2TP/dx^2 = - 6x + 12
d^2TP/dx^2 i.e - 6x + 12 at x = 5 is -6(5) + 12 = - 30+ 12 = -8 which is negative. So profit function is maximum at x = 5
Answer:
Supervised and Unsupervised Learning:
a. Unsupervised learning
b. Supervised learning
3. Supervised learning
4. Unsupervised learning
Explanation:
The key difference between supervised machine learning and unsupervised machine learning is that with supervised machine learning there is a training dataset (labeled data) on which the algorithm is trained to predict patterns. With unsupervised machine learning on the other hand, there is no training data. So, the algorithm discovers patterns on itself without reference to another labeled data or training dataset.
Answer:
Effect Corporate Change
Explanation:
Making formal statements, holding rites and rituals, utilizing employee training and coaching, demonstrating how a leader reacts to a crises, being a role model, and giving rewards, promotions, and bonuses are some of the teaching methods that organizations can utilize to effect corporate change. Change is one of the important and most difficult process for any organization. It needs to be carried out slowly as it has been manifested in the above given statement as well. Employees need to be given training, promotions, rewards and bonuses, they must be listened, their concerns should be addressed in order to make change process easy and smooth.
Answer:
A) True
Explanation:
Multilevel marketing is used by companies that engage in direct sales marketing and where each new salesperson or distributor must recruit more sales people to expand their activities. Some of the most famous multilevel marketing firms in the US are Avon and Herbalife.
The salesperson or distributor earns a fraction of the sales commissions that his/her recruited sales people sell. It is called the distributor's downline, and is shaped like a pyramid. In some countries this type of business is illegal because it works like a Ponzi scheme where new salespeople are recruited every time and in order to start working they must buy a certain amount of products. So a large percentage of the sales are made to other salespeople instead of customers.
Answer:
present worth = $7380
Explanation:
given data
initial cash flow = $23,000
geometric gradient = 2%
interest rate i = 10% per year
time period = 5 year
solution
we get here present worth cost that is
present worth = initial cash flow × 
......................1
put here value and we get
present worth = $23,000 × 
present worth = $23,000 × 0.32087
present worth = $7380
