Identify the equation of the circle that has its center at (-27, 120) and passes through the origin.

nasty-shy [4]

<h3><u>The equation of the circle that has its center at (-27, 120) and passes through the origin is</u>:</h3>

$(x + 27)^2 + (y - 120)^2 = 15129$

<em><u>Solution:</u></em>

<em><u>The equation of a circle is given as:</u></em>

$(x-a)^2+(y-b)^2=r^2$

Where,

(a, b) is the centre of the circle

r is the radius

We have the centre of the circle (-27, 120)

Therefore,

a = -27

b = 120

Given that, it passes through origin. which means, (x, y) = (0, 0)

Substitute (a, b) = (-27, 120) and (x, y) = (0, 0) in eqn

$(0 + 27)^2 + (0 - 120)^2 = r^2\\\\729 + 14400 = r^2\\\\r^2 = 15129$

Substitute $r^2$ = 15129 and (a, b) = (-27, 120) in eqn

$(x + 27)^2 + (y - 120)^2 = 15129$

Thus the equation of circle is found

The two-way frequency table below shows the preferred communication method of employees at a company, based on years of employme

Anna35 [415]

Answer:

The percentage of employees with 8 or more years at the company that reported that email is their preferred method of communication is 30.48%. I suppose there was a small typing mistake in option B.

Step-by-step explanation:

The proportion is the number of desired outcomes divided by the number of total outcomes.

The percentage is the proportion multiplied by 100.

In this question:

210 employees with 8 of more year.

Of those, 64 have the email as their preferred method of communication.

64/210 = 0.3048

0.3048*100 = 30.48%

The percentage of employees with 8 or more years at the company that reported that email is their preferred method of communication is 30.48%. I suppose there was a small typing mistake in option B.
