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

  • a is a leg
  • b is another leg
  • c is the hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Identify</u>

<em>a</em> = 12

<em>b</em> = 5

<em>c</em> = x

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute in variables [PT]:                                                                           12² + 5² = x²
  2. Evaluate exponents:                                                                                      144 + 25 = x²
  3. Add:                                                                                                                 169 = x²
  4. [Equality] Square root both sides:                                                                 ±13 = x
  5. Rewrite:                                                                                                           x = ±13

Since we are dealing with positive numbers, we can disregard the negative root.

∴ x = 13

What is the average rate of change of the function f(x)=5(2)^x from x = 1 to x = 5?
Mila [183]
Average rate of change refers to the slope of a function/equation. 
To solve this, plug in for both x values and calculate the average, or mean. 

x = 1 
f(1) = 5(2)^1 
      = 5(2) 
      = 10

x = 5 
f(5) = 5(2)^5
      = 5(32) 
      = 160

Now, you calculate the average: 
10 + 160 = 170 
Divide by 2 and you get 85.
