The answer should be 6! all you have to do is plug the numbers into the equation!
it would be like this:
-1^2+3^2+(-1)-3
doing all of that would equal 6!

A square has a side that measures 55 units. What is the area of a circle with a circumference that equals the perimeter of the s

Taya2010 [7]

<h3><u>Given</u>:-</h3>

$\rightarrow$ Side of square = 5.5 units.

$\rightarrow$ Circumference of circle = perimeter of square.

$\rightarrow$ Area of circle.

<h3><u>Solution</u>:-</h3>

$\rightarrow$ To find the area of circle firstly we have to find the perimeter of the square, then we will find the radius of circle and after that area of circle. So, let's begin:

$\rightarrow$ Perimeter of square = $\sf{4×side}$ (putting the value of side from the above given)

$\rightarrow$ $\sf{=\: 4 × 5.5}$

$\rightarrow$ $\sf{=\: 22units.}$

Therefore, perimeter of square = 22units.

Now, according to the question, perimeter of square = circumference of the circle. So, circumference of circle = 22units.

Now, using the formula of circumference of circle we can find the radius.

$\rightarrow$ Circumference of circle = $\sf{2πr}$ (putting the value of perimeter)

$\rightarrow$ $\sf{22\:=\: 2×3.14×r}$

$\rightarrow$ $\sf{22\:=\: 6.28×r}$

$\rightarrow$ $\sf{\frac{22}{6.28}\:=\: r}$

$\rightarrow$ $\sf{3.50units\:=\: r}$

Therefore, radius of circle = 3.50units.

Now, let's find area of the circle:

$\rightarrow$ Area of circle = $\sf{πr^2}$

$\rightarrow$ $\sf{πr^2}$ (putting the value of pie(π) and radius(r))

$\rightarrow$ $\sf{3.14×3.50^2}$

$\rightarrow$ $\sf{3.14×12.25}$

$\rightarrow$ $\sf{38.46unit^2}$

Therefore, area of circle = $\sf{38.46unit^2}$

picture included , please help, which of the following equations describe the line shown below (1,10) and (-3,2) *check all that

rosijanka [135]

Slope is $\text{m}=\frac{y_1-y_2}{x_1-x_2}=\cfrac{10-2}{1-(-3)}$
Then you use the equation
$\text{y=mx+b}$
Where b is the y-intercept. To find it, plug in x and y from one of the points. Say, point 1 (1,10):
$10=m(1)+b$
You know m (from above) and now you can solve for b.

Rearrange terms:
$y-b=mx$

And that will be the answer.

Make sense?
