Answer:

6 1/2 (mixed) or 25/4 (improper)

Step-by-step explanation:

Firstly, I made the mixed number an improper fraction; 5/4

Then I did the equation;

5/1 x 5/4 = 25/4

25/4 is 6.25 when divided, then made it a fraction; 6 1/4

Answer:

52.

Step-by-step explanation:

shaded = (3²) + (2²)

shaded = 9 + 4

shaded = 13

Unshaded = (3 x 2) + (2 x 3)

Unshaded = 6 + 6

Unshaded = 12

All = 12 + 13

All = 25

100 / 25 = 4

4 x 13 = 26 x 2

26 x 2 = 52.

The expression x^2 + 9 is an algebraic expression

x^2 + 9 cannot be factored because it is not a difference of two squares

The expression is given as:

x^2 + 9

Express 9 as the square of 3

x^2 + 3^2

The above expression is not a difference of two squares

Hence, x^2 + 9 cannot be factored because it is not a difference of two squares

The measure of the missing angle(a) in the isosceles triangle(two sides and angle equal) is 70 degrees.

An Isosceles triangle is a triangle that has two of it sides equal to each other and two of it angles equal to each other.

The base angle of an isosceles triangle are equal. Therefore, let's find angle a in the triangle.

55 + 55 + a = 180

Recall the sum of angle in a triangle is 180 degrees.

110 + a = 180

subtract 110 from both sides

110 - 110 + a = 180 - 110

a = 70 degrees

Step-by-step explanation:

1/3 x 1/3 =1/9

so

1/3 divided by 1/3 is 1/9

Answer:

56 degrees

Step-by-step explanation:

The angles x and 124 are supplementary angles, which means they add up to 180 degrees.

Thus,

We are left with this equation.

Answer:

Approximating has always been an important process in the experimental sciences and engineering, in part because it is impossible to make perfectly accurate measurements. Approximation also arises because some numbers can never be expressed completely in decimal notation. In these cases approximations are used.

Answer:

50°

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180° , that is

3rd + 30° + 100° = 180°

3rd + 130° = 180° ( subtract 130° from both sides )

3rd angle = 50°

Answer:

50 degrees

Step-by-step explanation:

In any triangle, there are 180 degrees. If we add 100 degrees plus 30 degrees to get 130, simply subtract that from 180 the get the measure of the third angle. (180-130= 50) Hope this helps!

Answer:

  72°

Step-by-step explanation:

The required angle of rotation can be found by considering the regular polygon to be inscribed in a circle. Each of its 10 vertices will be separated by a central angle of 360°/10 = 36°. So, the vertices a8 and a4 will be separated by a central angle of (8 -4)(36°) = 144°.

The angle a4-a1-a8 is an inscribed angle, so will have half the measure of the central angle intercepting the a4-a8 arc. The desired angle of rotation to map a4 to a8 is ...

  α = 144°/2 = 72°

The value of angle α is 72° if the regular polygon is inscribed in a circle and rotation centered at a_1

A polygon is a geometric figure with a finite number of sides in two dimensions. A polygon's sides or edges are made up of straight-line segments that are joined end to end to form a closed shape. The vertices or corners are the points where two line segments meet, and an angle is generated as a result.

Consider the regular polygon to be inscribed in a circle to get the required angle of rotation.

A center angle of 360°

=360°/10 = 36°

It will separate each of its 10 vertices.

The central angle:

= (8 - 4)×(36°) = 144°

An inscribed angle is a4-a1-a8:

So α will be:

α = 144/2 ⇒ 72°

Thus, the value of angle α is 72° if the regular polygon is inscribed in a circle and rotation centered at a_1

Study well!

By using the definition of even and odd functions, we will see that:

A function f(x) is even if:

f(x) = f(-x)

And the function is odd if:

f(-x) = -f(x).

Now let's check it for all the given functions.

a) f(x) = x^3 - 7/x

So this function is odd.

b)  f(x) = |-x|

This function is even.

c) f(x)=25-x^3

This function is neither odd nor even.

d) f(x) = 72-x^4

This function is even.
