The correct option is

The center is located at (1, 3), and the radius is 6. By making the given equation as in the general equation of the circle as following x^2 -2x +1+ y^2-6y+9=26+1+9 (x-1)^2+(y-3)^2=36=6^2 So, the coordinates of the center (1,3) And the radius=6

Select the correct answer and then click Done.
Dimas [21]

Answer:

f(x) = (x + 10)(x + 4)(x - 1)

Step-by-step explanation:

Given the zeros of a polynomial, say x = a and x = b, then

the factors are (x - a) and (x - b)

The polynomial is then the product of the factors

f(x) = (x - a)(x - b)

Here the zeros are x = - 10, x = - 4 and x = 1, thus the factors are

(x - (- 10)), (x - (- 4)) and (x - 1), that is

(x + 10), (x + 4) and (x - 1)

f(x) = (x + 10)(x + 4)(x - 1)

Mrs. Bailey has equal numbers of nickels and quarters but the value of the quarters is $1.80 more than the value of the nickels.
sdas [7]

The total value of all coins together is $2.7

A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line

Let the number of nickels and quarters be x.

Value of nickel = 5 cents = $0.05

Value of quarters = 25 cents = $0.25

Thus, the total value equals

0.05x +$1.80 = 0.25x

$1.80 = 0.25x - 0.05x

$1.80 = 0.2x

x = 1.80/0.2

x = 9 coins

Thus the total value of all coins together is  ($0.05+$0.25)x 9 = $0.3 x 9

= $2.7

Use the grouping method to factor this polynomial.
tankabanditka [31]

Answer:

C

Step-by-step explanation:

Given

x³ + 3x² + 3x + 9 ( factor first/second and third/fourth terms )

= x²(x + 3) + 3(x + 3) ← factor out (x + 3) from each term

= (x² + 3)(x + 3) → C
