A nationwide club begins a chapter near you. You research the membership of the club over the past few decades.
Phantasy [73]

Answer:

Option (d)

Step-by-step explanation:

From the given table,

Number of members in 1980 (t = 0) were 5400.

With the period of time number of members increased.

Let the number of years after 1980 = x

Therefore, line of best fit will be in the form of y = mx + b

Where b = Initial number of members = 5400

m = Increase in members in every 5 years duration

So the equation will be,

y = mx + 5400

From the given options,

Equation which matches to our equation is,

y = 310.58x + 5400

For the number of members in year 2022,

x = 2022 - 1980 = 42 years

y = 310.58(42) + 5400

y = 18445

Option (d) will be the answer.

Homer wants to identify the center and radius of the circle defined by the equation x2 + y2 - 14x +
Klio2033 [76]

Homer has made mistake in step 2

When you complete the square, you need to add the values to both sides of equation

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

<em><u>Given equation of circle:</u></em>

x^2 + y^2 -14x + 2y -25 = 0

Let us first calculate center and radius and find out where he did the mistake

<em><u>Step 1:</u></em>

Group the terms

x^2 -14x + y^2 + 2y = 25\\\\(x^2 -14x) + (y^2 + 2y) = 25

<em><u>Step 2:</u></em>

(x^2 -14x + 49) + (y^2 + 2y + 1) = 25 + 49 + 1

But homers step 2 is:

(x^2 -14x + 49) + (y^2 + 2y + 1) = 25

So homer has made mistake in this step

When you complete the square, you need to add the values to both sides of equation

But homer did not add 49 and 1 to right side of equation

Correct steps are:

(x^2 -14x + 49) + (y^2 + 2y + 1) = 75\\\\(x-7)^2 + (y+1)^2 = 75

Comparing general equation of circle,

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

Therefore, center is ( 7, -1) and radius is 8.66
