Answer:
109.30
Step-by-step explanation:
Answer:
The correct answer is: A = 1/2 bh V = integral A(x) from [-r, r].
Step-by-step explanation:
x^2 +y^2 = r^2 A = 1/2 bh b = 2y = 2sqrt[r^2 - x^2] so that gives A = 1/2 [ 2sqrt(r^2 - x^2)]h which gives A = sqrt[r^2 - x^2]h
Answer:
5.5
Step-by-step explanation:
11 divided by 2 is 5.5
22 divided by 4 is 5.5
44 divided by 8 is 5.5
The intersection of the diagonals of a parallelogram is always the midpoint of each of the diagonals, which means all we have to do is grab two opposite vertices and average their coordinates.
<span>Let's use W and Y. </span>
<span>(-1 + 6)/2 = 2.5 </span>
<span>(7 + -2)/2 = 2.5 </span>
<span>So our point is (2.5,2.5) </span>
<span>We could also use X and Z. </span>
<span>(8 + -3)/2 = 2.5 </span>
<span>(7 + -2)/2 = 2.5 </span>
<span>Again, we get (2.5,2.5)</span>
