well, first off let's check those two points, we know it's centerd at (-26 , 120) and we also know it passes through (0 , 0), so the distance between those two points is its radius
Answer:
2n² + n
Step-by-step explanation:
<u>Given sequence</u>:
3, 10, 21, 36, ...
Work out the first differences between terms:
As the <u>first differences</u> are <em>not </em>the same, work out the second differences.
As the second differences are the <u>same</u>, the sequence is quadratic and will contain an n² term.
The coefficient of n² is always <u>half of the second difference</u>. Therefore, as the second difference is 4, the coefficient of n² is 2.
To work out the nth term of the sequence, write out the numbers in the sequence 2n² and compare with the given sequence:
Therefore, we need to add n to 2n² to match the sequence.
Therefore, the nth term of this sequence is 2n² + n.

11. The area of the circle is pi×r^2 so pi×6^2= 113.1cm^2 rounded to 1 d.p.
The area of the rectangle is 4×4=16cm^2
So to find out the area of the shaded region, do 113.1-16= 97.1cm^2
12. The area of a rectangle is l×w so 40×18=720cm^2
The area of the triangle is 1/2(l×w) so 1/2(9×12)=1/2(108)= 54cm^2
So to find out the area of the shaded region, do 720-54= 666cm^2
