The value pie/2 is a solution for the equation 2sin^2x-sinx-1=0<br><br> true or false
Rasek [7]

Answer:

Yes, \frac{\pi }{2} is a solution

Step-by-step explanation:

Recall that sin(\frac{\pi }{2})=1. By replacing \frac{\pi }{2} in the given trigonometric equation, we get 0 (zero) as a result, so this value is a solution:

2*(sin(\frac{\pi }{2} ))^2-sin(\frac{\pi }{2})-1= 2*(1)^2-1-1=2-2=0

What statements describe the properties of a plane? Select three options.
Genrish500 [490]

Answer:

2)A plane has length and width.

3)A plane extends infinitely in all directions

5)A plane is a flat surface.

Step-by-step explanation:

We can think of a plane as a line in space with no height, only length and width.

Yes, a plane is a two-dimensional surface, hence it has length and width.

2)A plane has length and width (TRUE)

The plane surface extends infinitely far, therefore it extends infinitely in all direction.

3)A plane extends infinitely in all directions (TRUE)

5)A plane is a flat surface(TRUE)

The correct options are 2,3 and 5.
