A circle passes through the vertices of
Vika [28.1K]

Answer:

a) 14,1 cm

Step-by-step explanation:

If a circle passes through the vertices of a square then the diagonal of a square is a circle diameter.

We use Pytagoras Theorem to find out the length (L)  of the diagonal given that:

L²  =  (20)²  +  (20)²

L²  = 2* (20)²

L  = √2 * 20

L  = 1,4142* 20

L = 28,28 cm

L diagonal in the square is a diameter of the circle then radius of a circle is:

r = L/2   ⇒   r  = 28,28 /2   ⇒   r = 14,14 cm

The shape is composed of three squares and two semicircles. Select all the expressions that correctly calculate the perimeter of
VMariaS [17]

Answer:

120 + 20π

Step-by-step explanation:

Find the image of the question attached.

For the square;

Perimeter of a square = 4L

L is the side length of the square

From the diagram, L = 10

Perimeter of a square = 4(10) = 40

Perimeter of 3 squares = 3(40) = 120

For the semicircles:

Perimeter of a semicircle = 2πr/2 = πr

From the diagram;

L = radius of the semicircle = 10

Perimeter of a semicircle = π(10)

Perimeter of a semicircle = 10π

Perimeter of the two semicircles = 2(10π) = 20π

perimeter of the shape = perimeter of 3squares + 2 semicircles

perimeter of the shape = 120 + 20π

F(x) = x² + 10 <br>What is the average rate of change of f over the interval [ -2,-1?​
KIM [24]

Answer:

-3

Step-by-step explanation:

f(-2) = (-2)^2 + 10 = 14 -> (-2, 14)

f(-1) = (-1)^2 + 10 = 11 -> (-1, 11)

(11-14)/(-1-(-2)) = -3/1 = -3

What is the equation of the line that passes through the points (–12, –8) and (–17, –16)?
horsena [70]

Answer:

<em>firstly</em><em> find</em><em> the</em><em> gradient</em><em> given</em><em> by</em><em> the</em><em> equation</em>

<em>m=</em><em>y2-y1</em><em>/</em><em>x2-x1</em>

<em>in this </em><em>case</em><em> </em><em>x1 </em><em>is </em><em>-</em><em>1</em><em>2</em><em>,</em><em>x2 </em><em>is </em><em>-</em><em>1</em><em>7</em><em>,</em><em> </em><em>y1 </em><em>is </em><em>-8 </em><em>and </em><em>y2 </em><em>is</em><em>-</em><em>1</em><em>6</em>

<em>m=</em><em>-</em><em>1</em><em>6</em><em>+</em><em>8</em><em>/</em><em>-</em><em>1</em><em>7</em><em>+</em><em>1</em><em>2</em>

<em> </em><em> </em><em> </em><em>=</em><em>-</em><em>8</em><em>/</em><em>-</em><em>5</em><em> </em><em>or1.</em><em>6</em>

<em>then</em><em> </em><em>use </em><em>the </em><em>equation</em>

<em>y-y1</em><em>=</em><em>m(</em><em>x-x1</em><em>)</em>

y+8=1.6(x+12)

y+8=1.6x+19.2

y=1.6x+11.2

I hope this helps and sorry if it's wrong
