Answer 1
Answer:

Answer:

it’s the 3rd one:)

Step-by-step explanation:
Answer 2
Answer:

Answer:

  • In this situation, (h, k) = (-2, -3)
  • Radius = 8/2 = 4 units

Substitute them into the circle equation: (x - h)² + (y - k)² = r²

(x - (-2))² + (y - (-3))² = 4²

(x + 2)² + (y + 3)² = 4²

Now expand the equation:

(x + 2)² + (y + 3)² = 4²

(x + 2)(x + 2) + (y + 3)(y + 3) = 16

(x² + 2x + 2x + 4) + (y² + 3y + 3y + 9) = 16

x² + 4x + 4 + y² + 6y + 9 = 16

x² + y² + 4x + 6y + 13 - 16 = 0

x² + y² + 4x + 6y - 3 = 0

A) m=1

The equation for the circle is:

(x-8)^2 + (y-1)^2 = 49

If we take 'y' as 1, then

(x-8)^2 + 0 = 49

x-8 = √49

x = ±7 + 8

x = 15 or x = 1

your drapery business has just gotten a new client who needs 4 drapes. each one will need to be 8 feet by 5 feet and you must add an additional 6 inches on top and bottom for a hem. the customer has chosen the fabric but the store only has 6 linear yards of material. is that enough to make all the drapes? why or why not?

Answers

1. You have that:

 - The new client who needs 4 drapes.
 - Each dreape will need to be 8 feet by 5 feet. Therefore, the perimeter will be:

 P1=8 ft+8 ft+5 ft+5 ft
 P1=26 ft

 - You must add an additional 6 inches on top and bottom. Therfore, the perimeter will be:

 1 inch=0.0833 ft
 6 inches=0.499 ft≈0.50 ft

 P2= 2(0.50 ft++0.50 ft+8 ft+8 ft)
 P2=34 ft

 - Thefore, the total perimeter of the drape will be:

 Pt=26 ft+34 ft
 Pt=60 ft

 - The perimeter of 4 drapes will be:

 =60 ftx4
 =240 ft

 - The problem says that the store only has 6 linear yards of material. Therefore:

 6 yards=18 ft

 The answer is: It is not enough to make all drapes, because you need 240 ft of material and the store only has 18 ft.
