Step-by-step explanation:

<u>Step 1: Define</u>

<u />\displaystyle f(x) = 2(4)^x\\f(-2) \ is \ x = -2<u />

<u />

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em>:                    \displaystyle f(-2) = 2(4)^{-2}
  2. Exponents:                          \displaystyle f(-2) = 2(\frac{1}{16})
  3. Multiply:                               \displaystyle f(-2) = \frac{1}{8}

The average of 4 numbers is 5. What is their sum? explain you answer
maxonik [38]
To find an average you add all numbers together then divide by the amount of numbers that you added. So if there are 4 numbers you would divide by 4. By going backwards you can find the answer. Multiply 5 by 4 and you get 20, which is the answer.

Help wanted can someone help me and give me a short understanding of this
Citrus2011 [14]
Y = 104°
z = 24

Angle y° and (5z - 44)° are linear pairs, meaning that the two measures together will add up to 180°.
To solve for z, know that (5z - 44)° and 76° are vertical angles, meaning that both angles are the same.
So simply set them equal to each other to find z:
5z - 44 = 76
5z = 76 + 44
5z = 120
z = 24

Now to solve for y, remember that since (5z - 44)° and 76° are vertical angles, they are the same, meaning you can denote (5z - 44)° as simply 76°. Like I said earlier, y and 76° are a linear pair so simply subtract 76 from 180 to find y:
180 - 76 = 104°
