Which piecewise function represents the graph?
Anon25 [30]

Answer:

D

Step-by-step explanation:

If you look at the right side of each piecewise function, you will see the x-values. That is what we will be focusing on in this explanation. All four equations have x <u>></u> 4, and we know that to be true. If you look at the equation on the graph going South West, you will see that the endpoint is at x=1. Only 1 equation, D, has this in the piecewise function. To confirm it is D, you can see that 1<x<4 is also in the piecewise function, and all the values line up with their corresponding y-values.

Hope this helps! :)

Hello i need help with these questions asap!!
makvit [3.9K]

We use direct proportionality:

360⁰......Pi×R² (full circle)

120⁰.......x

x=120×pi×R²/360=pi×R²/3

x=pi×4²/3=16.76mi²

A=3×pi cm², for an angle of 2×pi/3=120⁰

In a similar way we compute the area of the full circle:

360.........x

120..........3×pi

x=3×pi×360/120=9×pi=3²×pi.

Thus the radius is 3cm.
