Answer:

D;

(x + 1/2)^2 + (y- √57)^2 = 81

Step-by-step explanation:

Mathematically, the general equation of a circle is given as;

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

where (a,b) represents the circle center and r represents the radius of the circle

Thus, we have this as follows;

(a,b) = (-1/2, √57) , r = 9

Substituting these values;

(x + 1/2)^2 + (y- √57)^2 = 9^2

(x + 1/2)^2 + (y- √57)^2 = 81

Simplify completely the quantity 5 times x to the third power plus 10 times x to the 2nd power plus 15 times x all over 5 times
dedylja [7]
The <u>correct answer </u>is:

x²+2x+3.

Explanation:

\frac{5x^3+10x^2+15x}{5x}

We need to divide each term of the numerator by the denominator.  For the <u>first term</u>:
\frac{5x^3}{5x}

Dividing the coefficients, we have 5/5 = 1.  
When dividing the variables, we use the quotient rule:  when dividing powers that have the same base, subtract the exponents.  This gives us:
x³/x = x³/x¹ = x³⁻¹ = x²

For the first monomial, this gives us 1x² = x².

The <u>second term</u>:
\frac{10x^2}{5x}

Dividing the coefficients, we have 10/5 = 2.
Dividing the variables, we again use the product rule:
x²/x = x²/x¹ = x²⁻¹ = x¹ = x

Together this gives us 2x.

The <u>third term</u>:
\frac{15x}{5x}

Dividing the coefficients, we have
15/5 = 3.
Dividing the variables, we have x/x; when you divide something by itself, the answer is 1.  This gives us:
3*1 = 3.

Together our quotient is x²+2x+3.
