Center ( 9,-8 ), passes through ( 19,22 )

katovenus [111]

Center at (h,k) and radius r is
(x-h)²+(y-k)²=r²

so given
center at (9,-8)

(x-9)²+(y-(-8))²=r²
(x-9)²+(y+8)²=r²

input the point (19,22) to find r²
x=19 and y=22
(19-9)²+(22+8)²=r²
10²+30²=r²
100+900=r²
1000=r²
10√10=r

well, the equation is
(x-9)²+(y+8)²=1000

The numbers 5, 6, 7, and 8 are randomly arranged to create a four-digit number. What is the probability that the number formed i

myrzilka [38]

Using the arrangements and the probability concept, it is found that there is a 0.75 = 75% probability that the number formed is not divisible by 4.

A probability is the number of desired outcomes divided by the number of total outcomes.

The number of possible arrangements of n elements is given by $A_n = n!$

In this problem, there are 4 elements, hence $n = 4, T = A_4 = 4! = 24$ .

A number is a multiple of 4 if the number composed by it's last 2 digits are multiples of 4.

Hence, the possible options for the last 2 digits are: 56, 68, 76.

For each of them, there are $A_2 = 2! = 2$ options for the first 2 digits, hence, there will be 2 x 3 = 6 multiples of 4.

The other 18 numbers formed are not divisible by 4, hence:

$p = \frac{18}{24} = 0.75$

0.75 = 75% probability that the number formed is not divisible by 4.

Find the minimum and maximum possible areas of a rectangle measuring 2 km by 5 km.Find the minimum and maximum possible areas of

jeka57 [31]

Answer:

Minimum possible area = 6.75 km^2

Maximum possible area = 13.75 km^2

Step-by-step explanation:

This question relates to significant figures so assuming that each of the given values is rounded off to the nearest kilometer.

So we can find the minimum and maximum possible areas of the rectangle.

Minimum possible area of rectangle = 1.5 × 4.5 = 6.75 square kilometers

Maximum possible area of rectangle = 2.5 × 5.5 = 13.75 square kilometers
