777dan777 [17]

Answer:

Can not be determined.

Step-by-step explanation:

We can easily notice that the limit is x tends to infinity, whereas x is not present in the given function, we are given (1 + 1/n). So we can not evaluate the given limit for x as parameter, we must have some function of x to solve this problem.

Hence, option C is correct i.e. the limit can not be determined.

Vesnalui [34]

Complete question is;

Jackson has to repaint some classroom bookcases. He has 2 gallons of paint. All the bookcases are the same size and each requires 2/5 gallon of paint. How many bookcases is he able to repaint with the amount of paint?

Answer:

5 books

Step-by-step explanation:

Jackson has 2 gallons of paint

Now, for us to find the number of bookcases the Jackson will be able to repaint if each bookcase requires 2/5 gallon, we will just divide 2 by 2/5

Thus;

Number of book cases Jackson will be able to repaint = 2 ÷ 2/5

Thus gives; 2 × 5/2 = 5 books

LenKa [72]

Answer:

<h2>Square.</h2>

Step-by-step explanation:

The parallelogram that has those characteristics is the square.

The square is perfectly symmetric, both diagonals are congruent, because all sides of the square are congruent. Also, the diagonals bisects each angle of the square, creating triangles. Those triangles have 45° angles at their base and the third-angle is 90°, that is, it's a right triangle, where that right angle is between diagonals.

Therefore, a square has congruent and perpendicular diagonals, they have the same midpoint, and their slopes are opposite reciprocals of each other because that's the definition of perpendicularity.

Therefore, the right answer is square.
