What is the equation of the circle whose diameter has endpoints (8,-2) and (-2,6)?

klemol [59]

Answer:

$(x-3)^{2} +(y-2)^{2}=41$

Step-by-step explanation:

step 1

Find the diameter of the circle

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

$A(8,-2)\\E(-2,6)$

substitute the values

$d=\sqrt{(6+2)^{2}+(-2-8)^{2}}$

$d=\sqrt{(8)^{2}+(-10)^{2}}$

$d=\sqrt{164}\ units$

$d=2\sqrt{41}\ units$

step 2

Find the center of the circle

The center is the midpoint of the diameter

The center is equal to

$C=(\frac{8-2}{2},\frac{-2+6}{2})$

$C=(3,2)$

step 3

Find the equation of the circle

The equation of the circle in center radius form is equal to

$(x-h)^{2} +(y-k)^{2}=r^{2}$

we have

(h,k)=(3,2)

$r=2\sqrt{41}/2=\sqrt{41}\ units$ ---> the radius is half the diameter

substitute

$(x-3)^{2} +(y-2)^{2}=(\sqrt{41})^{2}$

$(x-3)^{2} +(y-2)^{2}=41$

National polls are often conducted by asking the opinions of a few thousand adults nationwide and using them to infer the opinio

Valentin [98]

Answer:

Sample: few thousand adults

Population: all the adults

Step-by-step explanation:

A sample is a subset of the population, selected randomly.

In this case:

The sample consist of the few thousand adults selected to determine the opinions about the National polls.

The population consist of all the adults belonging to the said nation.

Consider an example about the new President election.

To determine which of the two candidates (say A and B) has a higher probability of winning the President election, the election society took a random sample of voters and asked who they think will be a better president.

The sample selected will be large enough, probably 10% of the population of all voters.

From this study it can be estimated which candidate has the higher chance of winning.
