Answer:

(x + 5)^2 + (y + 8)^2 = 6^2

Step-by-step explanation:

A circle formula: (x - h)^2 + (y - k)^2 = r^2

We are given diameter. To find the radius divide diameter by 2.

d = 12

12/2 = r = 6

H and K are given to be (-5 , -8)

(x - (-5))^2 + (y - (-8))^2 = 6^2

(x + 5)^2 + (y + 8)^2 = 6^2

I have plot this equation to confirm my answer is correct where the origin is (-5 , -8) and has a radius of 6.

Answer:

The answer to your question is: Yes, x - 5 is a factor of the polynomial.

Step-by-step explanation:

To answer this question you need to divide the polynomial by the factor and if there is nothing left, they are factor.

x -5

x² + x -2

x-5 x³ -4x² -7x +10

-x³ + 5x²

x² - 7x

-x² + 5x

-2x + 10

+2x -10

0 0 These zeros tell us that the linear

expression is a factor of the polynomial

How can you solve standard form and intercept form?

laiz [17]

Answer:

The standard form of such an equation is Ax + By + C = 0 or Ax + By = C. When you rearrange this equation to get y by itself on the left side, it takes the form y = mx +b. This is called slope intercept form because m is equal to the slope of the line, and b is the value of y when x = 0, which makes it the y-intercept.

One 3.8 lb bag of fertilizer covers 1000 square feet each bag cost $9.95 the square feet of the yard is 1307.25 ft squared how m

zaharov [31]

Answer:

Exactly 1.30725 bags are needed to cover the garden.

Step-by-step explanation:

We have a yard with a surface of 1307.25 square feet.

We know that one bag of fertilizer covers 1000 square feet.

We want to know how many bags are needed to cover the garden. We can calculate the number of bags as:

$B=S\cdot b=1307.25\;\text{sq.ft.}\cdot \dfrac{1\,\text{bag}}{1000\,\text{sq.ft.}}=1.30725\,\text{bags}$

B: number of bags needed for the yard.

S: surface of the yard.

b: number of bags per square foot.
