Determine the equation of the circle graphed below.

Diano4ka-milaya [45]

Answer:

$(x - 6)^2 + (y - 2)^2 = 4$

Step-by-step explanation:

Required

The equation of the circle

The equation of a circle is:

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

Where:

$Center = (h,k)$

$radius \to r$

From the graph, we have

$(h,k) = (6,2)$

$r = 2$

So:

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

$(x - 6)^2 + (y - 2)^2 = 2^2$

$(x - 6)^2 + (y - 2)^2 = 4$

The Line graph shows the number of marks Stacey scorer in her homeworks.

weqwewe [10]

Given:

The line graph shows the number of marks Stacey scored in her homeworks.

We need to determine the Stacey's mean score.

Mean score:

The total number of marks is given by

$(0\times 4)+(1 \times 5)+(2\times 3)+(3\times 4)+(4 \times 3)+(5 \times 1)$

Simplifying, we get;

$0+5+6+12+12+5=40$

Thus, the total number of marks is 40.

Sum of the number of marks scored is given by

$4+5+3+4+3+1=20$

Thus, the sum of the marks scored is 20.

The mean is given by

$Mean=\frac{40}{20}$

$Mean=2$

Therefore, Stacey's mean score is 2 marks.

I really need help . z = m - x, for x , i have tried x=m-z and thats incorrect.

ch4aika [34]

z = m - x

To solve for x, we can treat this like a typical algebraic problem.

We need to isolate x on one side.

Add x to both sides

z + x = m

Subtract z from both sides

x = m - z

This should be the answer.
