andrezito [222]

Answer:

The answer to your question is (x + 3)² + (y + 6)² = 2

Step-by-step explanation:

Endpoints (-4, -7) and (-2, -5)

Process

1.- Find the length of the radius

d = $\sqrt{(x2 - x1)^{2} + (y2 - y1)^{2} }$

d = $\sqrt{(-2 + 4)^{2}+ (-5 + 7)^{2} }$

d = $\sqrt{2^{2} + 2^{2} }$

d = $\sqrt{4 + 4}$

d = $\sqrt{8}$

Radius = $\frac{\sqrt{8} }{2}$ = $\sqrt{2}$

2.- Find the center

Xm = $\frac{-4 - 2}{2} = \frac{-6}{2} = -3$

Ym = $\frac{-7 - 5}{2} = \frac{-12}{2} = -6$

Center = (-3, -6)

3.- Write the equation

(x - h)² + (y - k)² = r²

(x + 3)² + (y + 6)² = ( $\sqrt{2}$ )²

(x + 3)² + (y + 6)² = 2

Skylar makes turkey sandwiches for a family reunion. He purchases 5 pounds 4 ounces of sliced turkey for $26.88. What is the uni

Advocard [28]

Answer:

The unit cost per ounce for turkey skylar is $ 0.316

Step-by-step explanation:

The total amount of sliced turkey = 5 pounds + 4 ounces

The total cost of turkey slice = $26.88

Now, as we know

1 pounds = 16 ounces

∴ 5 pounds = 16 × 5 = 80 ounces

So, the total amount is 5 pounds + 80 pounds = 85 pounds

∵ 85 pounds of turkey sliced cost $ 26.88

∴ 1 pounds of turkey sliced cost $ $\frac{26.88}{85}$ = $ 0.316

Hence the unit cost per ounce for turkey skylar is $ 0.316 Answer
