Answer:

a) The center coordinates O is (0,0)

b) The radius C = 15

Step-by-step explanation:

The given equation of the circle is : $x^{2} + y^{2} = 225$

Now, general form of the equation of the circle is:

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

where (h,k) are the center co -ordinates and r is the radius of the circle.

Comparing the general equation with the given equation, we get

$(x-0)^{2} + (y - 0)^{2} = (15)^{2}$

So, here the center coordinates (h,k) = (0,0)

And the radius of the given circle is r = 15

Answer:

$Length\ of\ the\ long\ piece=40\ meters\\\\Length\ of\ the\ short\ piece=17\ meters$

Step-by-step explanation:

Let be "s" the length in meters of the short piece and "l" the lenght in meters of the long piece.

Set up a system of equations:

$\left \{ {{s+l=57} \atop {s=l-23}} \right.$

Apply the Substitution Method to solve the system. Substitute the second equation into the first equation and solve for "l":

$(l-23)+l=57\\\\2l=80\\\\l=\frac{80}{2}\\\\l=40$

Susbstitute the value of "l" into the second equation in order to find the value of "s". This is:

$s=40-23\\\\s=17$

The correct simplification of 8x2(5x 2x2 − 3) is $16x^{4} +40x^{3} -24x^{2}$

<h3>What do you mean by simplification?</h3>

Simplifying procedures is one way to achieve uniformity in work efforts, expenses, and time. It reduces diversity and variety that is pointless, harmful, or unnecessary.
Making anything simpler is the act or process of simplification. Everyone is in favor of streamlining court procedures.
Certain "solving" issues are connected to "simplification" issues. Parentheses and even nested grouping symbols can be found in some equations, just like in some expressions. Whether we're working with equations (so we're also solving) or expressions (and only simplifying), the simplification procedure is the same in both cases.

The correct simplification of 8x2(5x 2x2 − 3).

$8x^{2} (5x+2x^{2+1} -3)=8*2x^{2+2} -8*3x^{2}$
