I think D can be inscribed
Answer:
B
Step-by-step explanation:
The part of the function where x <=2 is a line, so we can rule out C and D. Lastly, the part of the function where x<=2 has a slope of -2, so we can rule out A. That leaves us with the only possible answer B
The surface area is found by finding the area of all shapes creating the surface, and then adding them together.
Example:
If we have a 5 x 5 x 5 cube, we will find all six sides. Since 5 x 5 is 25, and 25 x 6 = 150, the surface area of this example cube will be 150 units².
<em> Why the x 6? Since it is a cube all the sides have the same area, and a cube has 6 sides.</em>
Answer:
cm.
Step-by-step explanation:
A diagonal of a square + two of its sides creates a <em>45-45-90 triangle</em>. The relation between the lengths of said triangle is <em>1:1:√2</em>. In this case the diagonal is the √2 of the ratio.
That means that the side length should be <em>18/√2</em>, as this times √2 makes 18.
18/√2 simplifies to (18√2)/2 = (9√2)/2.
