The length of the arc is 4π.

<u>Step-by-step explanation</u>:

Given,

  • Diameter = 24 ft
  • radius, r = diameter/2
  • r = 24/2 = 12 ft
  • central angle, ∅ = 60°

Arc length = ∅/360° (2πr)

⇒ 60°/360° (2π\times12)

⇒ 24π/6

⇒ 4π

∴ The length of the arc is 4π.

What is the measure of a counterclockwise rotation about the spinnercenter that maps label i to label f? 108 72 36 252
ankoles [38]
Answer: First option 108°

Each label is equivalent to an angle of:
Angle=360°/n
Number of label: n=10
Angle=360°/10
Angle=36°

To map label i to label f in a counterclockwise rotation, we must pass by 3 regions: i to h, h to g, and g to f; each one of 36°. Then the measure of a counterclockwise rotation about the spinnercenter that maps label i to label f is:
Measure=3(36°)
Measure=108°

Can someone tell me if I did this right? If it's wrong can you tell me how to do it step by step? Thanks
Lesechka [4]

Hi there!

So first off, here are little definitions you need to know in order to be able to answer your question :

<u>Constant</u> means that the rates of change are the same.

<u>Variable</u> means that the rates of change are different.


But from what I can see, you don't even need those definitions because you got both answers right!


Continue your great work! If there's anything just let me know! :)

If f(x) = 4x + 8 and g(x) = (x+4,<br> what is (fºg)(12)?
svetlana [45]

Answer:

72

Step-by-step explanation:

f(x) = 4x+8\\g(x) = x + 4\\\\1. f(g(x)) = 4(x+4) + 8\\2. f(g(x)) = 4x + 16 + 8\\3. f(g(x))=4x + 24\\\\4. f(g(12)) = 4(12) + 24\\5. f(g(12)) = 48 + 24 = 72\\

To do these, you have to place the entire function inside the parent function's variables.

You are inputting the value of the function g(x) into f(x)
