Answer: (x-3)^2=10

Step-by-step explanation:

Nikitich [7]3 years ago

Solve for x over the real numbers: by completing the square:

5 x^2 - 30 x = 5

Divide both sides by 5:

x^2 - 6 x = 1

Add 9 to both sides:

x^2 - 6 x + 9 = 10

Write the left hand side as a square:

(x - 3)^2 = 10

Take the square root of both sides:

x - 3 = sqrt(10) or x - 3 = -sqrt(10)

Add 3 to both sides:

x = 3 + sqrt(10) or x - 3 = -sqrt(10)

Add 3 to both sides:

Answer: | x = 3 + sqrt(10) or x = 3 - sqrt(10)

the trigonometric functions are not one-to-one. but mathematicians wanted to define inverse functions. before that could be done
oee [108]

The restricted domains for the inverse trigonometric functions are the quadrants, that can be each of the following intervals:

  • 0 < x < 0.5π.
  • 0.5π < x < π.
  • π < x < 1.5π.
  • 1.5π < x < 2.

<h3>What are equivalent angles?</h3>

Each angle on the second, third and fourth quadrants will have an equivalent on the first quadrant. The relevance to these equivalent angles is that they may have equal values for the trigonometric functions, meaning that they are not one-to-one.

If we restrict the domain of the trigonometric functions in any of the four quadrants, we guarantee that they are one-to-one, hence the restricted domains are given as follows:

  • 0 < x < 0.5π.
  • 0.5π < x < π.
  • π < x < 1.5π.
  • 1.5π < x < 2.

The surface area of this cube is 864 square yards. What is the value of q?
earnstyle [38]

Answer:

Volume  

=

512

cubic feet

Explanation:  

A cube has  

6

faces all with equal area.

If the total surface area of the cube is  

384

sq.ft.

then each face has an area of  

384

÷

6

=

64

sq.ft.

Each face of a cube is a square and if we denote the length of an edge as  

E

then the area of a face (in this case  

64

sq.ft.) is equal to  

E

2

XXX

E

2

=

64

sq.ft.

XXX

→

E

=

8

sq.ft.

The volume of a cube with edges of length  

E

is  

E

3

In this case  

Volume

=

E

3

=

8

3

=

512

sq.ft.

Hope i helped
