We have to identify the statement about the plane which is not true.

1. Consider the first statement,

" A plane can be thought of as flat". It is true as plane is a flat surface.

2. Consider the second statement,

"The surface of a plane is made up of points". It is true as plane is a flat surface which is made up of points.

3. Consider the third statement,

"A plane can be seen". It is not true as plane is a flat surface which can not be seen.

4. Consider the fourth statement,

"A plane extends infinitely in all directions". It is true as plane is a flat surface that extends infinitely along its edges.

What is the value angle marked x?

Anton [14]

Answer: x =104

Step-by-step explanation:

If we draw the black line shown in the figure, two isosceles triangles are formed, and the base angles of the isosceles triangles are the same. The red angles are the same and the green ones too. The 104 degree angle is the sum of the red angle and the green angle, and x is also the sum of the red angle and the green angle, therefore x = 104.

If f(x) = (xm + 9)2, which statement about f(x) is true?

Marina CMI [18]

Answer:

The correct statement for the given function is:

f(x) is an even function for all even values of m.

Step-by-step explanation:

The correct statement for the given function is:

f(x) is an even function for all even values of m.

The given function(x^m+9)^2 is a quadratic equation. The term Quadratic means the variable gets squared. if m is an even number, that would result also to an even function....

a rectangle rug has a perimeter of 146 ft the width of the rug is 5 feet more than three times the length find the length and th

dem82 [27]

Answer:

The length = 56 feet and the width = 17 feet.

Step-by-step explanation:

We can set up 2 equations to solve this. Let the length of the rug be x, then

x = 3w + 5 where w = the width. ( looks like you got the width and the length mixed up. The length is the longest side)

The perimeter = 2x + 2w = 146 so we have the 2 equations:

x = 3w + 5

2x + 2w = 146

Now we substitute for x in the second equation:

2(3w + 5) + 2w = 146

6w + 10 + 2w = 146

8w = 136

w = 17 feet,

and x = 3(17) + 5 = 56 feet.

What is the domain and range of the equation y=500(1.08)^x

Marina CMI [18]

(x) is an element of a real number. This means it could be an integer, fraction or irrational number.

* As x approaches infinity, y approaches infinity.

* As x approaches minus infinity, y approaches 0.
