The daily profit in dollars made by an automobile manufacturer is

P(x) = -35x2 +2,100x - 20,000

where x is the number of cars produced per shift. Find the

maximum possible daily profit.

The maximum possible daily profit is $11,500.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

It's vertex is the point

In which

If a<0, the vertex is a maximum point, that is, the maximum value happens at , and it's value is

In this question:

The maximum daily profit happens when cars are sold. This profit is

So

The maximum possible daily profit is:

The maximum possible daily profit is $11,500.

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
