Step b is wrong. The slope is the change in y over the change in x.

Step b should be (18- 8)/( 10-6)

= 10/4

= 5/2

____ [38]

Given :

A circle is inscribed in a square with a side length of 144.

So, radius of circle, r = 144/2 = 72 units.

To Find :

The probability that the point is inside the circle.

Solution :

Area of circle,

$A_c = \pi r^2\\\\A_c = 3.14 \times 72^2\ units^2\\\\A_c = 16277.76 \ units^2$

Area of square,

$A_s = (2r)^2\\\\A_s = ( 2 \times 72)^2\ units^2\\\\A_s = 20736\ units^2$

Now, probability is given by :

$P = \dfrac{A_c}{A_s}\\\\P = \dfrac{16277.76}{20736}\\\\P = 0.785$

Therefore, the probability that the point is inside the circle is 0.785 .

Responda:

a) 3 e 4

Explicação passo a passo:

Deixei :

Número de cães = x

Número de gatos = y

2x + 3y = 17 - - - - (1)

x - y = 1 - - - - (2)

De (2)

x = 1 + y

Coloque em (1)

2 (1 + y) + 3y = 17

2 + 2y + 3y = 17

2 + 5y = 17

5y = 17 - 2

5y = 15

y = 15/5

y = 3

x = 1 + y

x = 1 + 3

x = 4

Número de cães = x = 4

Número de gatos = y = 3
