Answer: 1st one it 22.3(1-0.014)^t second one is 24.5(1-.0075)^t

And it’s multiplication

Step-by-step explanation: alright so it’s lowering per year so if you evaluate every equation this makes the most sense because when you include “(1-)” it means percentage decrease and “(1+)” is percentage increase so this one make the most sense the other have some kind of increase rather than decrease

  • [Right Triangles Only] Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

<u>Step 1: Define</u>

We are given a right triangle. We can use PT to solve for the missing length.

<u>Step 2: Identify Variables</u>

Leg <em>a</em> = 6

Leg <em>b</em> = <em>x</em>

Hypotenuse <em>c</em> = √89

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Set up equation:                    6² + x² = (√89)²
  2. Isolate <em>x</em> term:                        x² = (√89)² - 6²
  3. Exponents:                             x² = 89 - 36
  4. Subtract:                                 x² = 53
  5. Isolate <em>x</em>:                                 x = √53
