Starting on the far right, ones, tens, hundreds, thousands, ten thousands, hundred thousands and millions.
Answer:
116
Step-by-step explanation:
8.2 / 2 = 4.1
a = 
0.5 x 8.2 x 5.6736 = 23.2618
23.2618 x 5 = 116.309 = 116
This can help you
a) since it is discrete we need to think about the sum thing
it it was continuous we would look at an integral thing
so I think if I remember correctly we need to find c such that
<span><span>∑<span>i=0</span>3</span>c(<span>x2</span>+4)=1
b) </span>
problem b is a similar setup
There are a few ways to go about doing this, but the easiest is portably to break it up into three shapes: two identical triangles, and a rectangle. The area of one triangle is:
1/2 (10x8) = 40, so the area of two triangles is 80.
The area of the square is 20 x 8, which is 160.
The total area is the sum of the two:
80 + 160 = 240, and this is your total area.
