Jenna collected data modeling a company's company costs versus its profits. The data are shown in the table:

Statement 3:

The function is increasing from x = 0 to x = 1 is the true statement.

Solution:

Statement 1: The function is decreasing from x= –2 to x = 1

At x = –2, the function value is 2.

At x = –1, the function value is –3.

At x = 0, the function value is 2.

At x = 1, the function value is 17.

So, the value of the function is not constantly decreasing or increasing.

Hence it is false statement.

Statement 2: The function is decreasing from x = –1 to x = 0

At x = –1, the function value is –3.

At x = 0, the function value is 2.

From –3 to 2, the value is increasing.

Hence it is false statement.

Statement 3: The function is increasing from x = 0 to x = 1

At x = 0, the function value is 2.

At x = 1, the function value is 17.

Hence it is true statement.

Statement 4: The function is decreasing from x = 0 to x = 1

It is already proved in statement 3.

Hence it is false statement.

Therefore, the function is increasing from x = 0 to x = 1 is the true statement.

Alice and Amy decide to meet at a party. From a corner of the party hall, Amy spots Alice at the corner of the hall diagonally o

zlopas [31]

Alice and Amy are standing on the 2 opposite endpoints of the diagonal of a rectangle. (Well, this is the best way to think of the situation geometrically.)

The shortest distance is certainly when Amy walks straight through the diagonal. So, we need to find the length of the diagonal.

A diagonal divides a rectangle into 2 congruent (identical) right triangles. The sides of any of these 2 triangles are 100 ft and 60 ft, thus we can find the diagonal by the Pythagorean theorem:

$|Diagonal|^2=100^2+60^2=10,000+3,600=13,600$ ,

so,

$|Diagonal|= \sqrt{16,600}\approx117$ (ft).

Answer: 117 ft
