Answer:

A. 3

Step-by-step explanation:

Hello

X^2 + 8X + (8/2)^2 + Y^2 + 14Y + (14/2)^2 = (8/2)^2 + (14/2)^2-56

(X+4)^2 + (Y+7)^2 = 16 + 49 - 56

(X+4)^2 + (Y+7)^2 = 9

Then

The radius for that circle is 3

Best regards

Answer:

  x ≈ 136.7 ft

Step-by-step explanation:

As you have marked, the relevant sides are the adjacent side and the hypotenuse. The mnemonic SOH CAH TOA reminds you ...

  Cos = Adjacent/Hypotenuse

For this triangle, that means ...

  cos(43°) = (100 ft)/x

  x = (100 ft)/cos(43°) . . . . . . . . . . multiply both sides by x/cos(43°)

  x ≈ 136.73 ft

The length x is about 136.7 feet.

Why does -2.4-(-7)have the same result as -2.4+7? Explain your reasoning.
asambeis [7]

Answer:

-2.4-(-7) has the same result as -2+7 because the negative sign and the minus sign cancel each other out. Think of it like this. If you cross the negative sign and the minus sign together, then it makes a plus sign.

Step-by-step explanation:

I gave a basic answer. You might have to elaborate more on this.
