Answer:

Step-by-step explanation:

(x-1)²+(y-2)² =4 compare the given equation with the general one

(x-h)² +(y-k)² =r², where (h, k) are coordinates of the center and r is radius

so center is at ( 1, 2) and radius is 2

Amelia wants to paint three walls in her family room. Two walls are 26 feet long by 9 feet wide. The other wall is 18 feet long
sattari [20]
Given:
Wall 1 & 2 : 26 ft by 9 ft
Wall 3 : 18 ft by 9 ft

Area 1 : 26 ft x 9 ft = 234 ft²
Area 2 : 26 ft x 9 ft = 234 ft²
Area 3 : 18 ft x 9 ft = 162 ft²

Total Area : 234 ft² + 234 ft² + 162 ft² = 630 ft²

1 Gallon = 250 ft²

630 ft² ÷ 250 ft² per gallon = 2.52 gallons

son4ous [18]

Answer:

  • A. 2, B. 3, C.1

Step-by-step explanation:

Find the y-intercepts, this should be sufficient to match with the graphs.

A.

  • x = 0 ⇒ y = 1
  • x = 0 ⇒ y = - 1

This is the graph 2

<h3 />

B.

  • x = 0 ⇒ y = - 2
  • x = 0 ⇒ y = 2

This is the graph 3

<h3 />

C.

  • x = 0 ⇒ y = - 2
  • x = 0 ⇒ y = - 2

This is the graph 1

(1+5/6)(1-5/6)<br><br> I don't understand it
ipn [44]
(a+b)(a-b) = a^2 - b^2

(1+5/6) (1-5/6) = 1^2 - (5/6)^2 = 1 - 25/36 = 36/36 - 25/36 = (36-25)/36 = 11/36

11/36 is your answer
