- [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 find the missing length.
<u>Step 2: Identify Variables</u>
Leg <em>a</em> = 9
Leg <em>b</em> = <em>x</em>
Hypotenuse <em>c</em> = 13
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitute [PT]: 9² + x² = 13²
- Isolate <em>x</em> term: x² = 13² - 9²
- Exponents: x² = 169 - 81
- Subtract: x² = 88
- Isolate <em>x</em>: x = 2√22
- Evaluate: x = 9.38083
- Round: x ≈ 9.4
Add the x's and divide by 2 and then add the Y's and divide by 2
X: (-8 + -7)/2 = -15/2
Y: (-7+-8) /2 = -15/2
midpoint = (-15/2, -15/2)
Answer is C
Answer:
g(x) = 3x² + 7
Explanation:
Here the f(x) is translated up 5 units, so we shall increase y axis by + 5
<u>so new equation:</u> g(x) = 3x² + 2 + 5 ➛ g(x) = 3x² + 7
- check the image given below. The red line is f(x) and blue line g(x)
