What is the area of the figure? How do you find it?
1 answer:
The area of a square is just side times side. So 3 * 3 = 9.
There are 4 half-circles which is the same as 2 full circles. Area of a circle is pi * the radius squared or
.
So we do 2(pi * (1.5)²) >> 2(2.25pi) = 4.5pi.
Now we add our two areas together. So the area of the whole thing is represented by the equation 4.5pi + 9. Plug this into a calculator to get your accurate measurement.
4.5pi + 9 ≈ 23.137 m²

Step-by-step explanation:
You can obtain any two points on the graph of and use it to draw its graph.
When x=0,
So you plot (0,2)
When x=1,
You again plot (1,-71).
With a straight edge you can now draw a straight line through the two points.

Answer:
1. Y
2. N
3. N
4. N
Step-by-step explanation:
Let's use the second equation, since it seems to be easier to use.
To check if an ordered pair is a solution, plug it in to the equation.
1. --> Y
2. --> N
3. --> N
4. --> N
Edit : The 4th equation doesn't work for the first equation, whereas the first one still does.
