The area of the figure formed by the square and semicircle is T = 22.28 cm²

A square is a four sided quadrilateral with all of the side having equal lengths. The total internal angle of a square is 360° with each side perpendicular to each other.

A square is a 4 sided polygon where all the sides are of equal length.

The area of the square is the square of any one of its side

Let a be the side of the square

Area of the square = a²

Given data ,

Let the area of the square be represented as A

Now , the value of A is

Let the area of the semicircle be S

Let the total area of the figure be T = S + A

where A = ( 4 )² = 16 cm²

And , S = ( πr² ) / 2

S = 3.14 x ( 2 )² / 2

S = 6.28 cm²

So , the total area T =6.28 cm² + 16 cm² = 22.28 cm²

Hence , the area of the figure is T = 22.28 cm²

Answer:

5/8 =x

Step-by-step explanation:

2 ^ ( 3x-5) = ( 1/32) ^x

Rewriting 1/32 as 2 ^ -5

2 ^ ( 3x-5) = ( 2^-5) ^x

We know that a^b^c = a^ ( b*c)

2 ^ ( 3x-5) = ( 2) ^-5x

Setting the exponents equal

3x-5 = -5x

Subtract 3x from each side

3x-5-3x = -5x-3x

-5 = -8x

Divide each side by -8

-5/-8 = -8x/-8

5/8 =x

Answer:

So he will need 168 feet of fencing.

Step-by-step explanation:

The perimeter formula of a rectangle is P=(2xL)+(2xW)

The length is 12 and the width is 9.

First, do P=(2x12)+(2x9), P=24+18 P=42 feet

Next, since there are four pens multiply the perimeter of 1 pen by 4.

4x42=168 feet of fencing

So, Don will need 168 feet of fencing.

The value of  p + q + r + s in the equation 0.1{(5x + 4)(4x - 9)}.

A quadratic equation is an algebraic expression in the form of variables and constants.

A quadratic equation has two roots as its degree is two.

Given, 2x² - 2.9x - 3.6.

Now, 0.1(20x² - 29x - 36).

= 0.1{4x(5x + 4) - 9(5x + 4)}.

= 0.1{(5x + 4)(4x - 9)}.

∴ p + q + r + s = 5 + 4 + 4 - 9.

p + q + r + s = 4.

Answer:

Axis of symmetry:  x = 5

Vertex form:  y = -4(x - 5)² + 3

Step-by-step explanation:

Given ordered pairs: (2, -33)  (3, -13)  (4, -1)  (5, 3)  (6, -1)

Axis of Symmetry

As this is a parabola, it will be symmetrical.  

To determine the axis of symmetry, identify two ordered pairs that have the same y-values and find their midpoint.

Two ordered pairs with the same y-value:  (-4, 1)  and  (6, -1)

Midpoint of x = 4 and x = 6 is:  x = 5

Therefore, the axis of symmetry is x = 5

Vertex form

Vertex form of a quadratic equation:  y = a(x - h)² + k

(where (h, k) is the vertex)

The axis of symmetry is the x-value of the vertex of the parabola.

As we have been given the point when x = 5, the vertex is:  (5, 3)

Substituting this into the formula:

⇒ y = a(x - 5)² + 3

To find the value of a, substitute any of the other points into the formula and solve for a.

Using (4, -1)

⇒ a(4 - 5)² + 3 = -1

⇒ a(-1)² = -4

⇒ a = -4

Therefore, the vertex form of the parabola is:

y = -4(x - 5)² + 3

First, find the lowest common denominator (LCD):

Next, convert the fractions to a base of 12.
[tex]\frac{2}{3} * \frac{4}{4} = \frac{8}{12}[/tex]

[tex]\frac{1}{4} * \frac{3}{3} = \frac{3}{12}[/tex]
