Answer:
That's a lot of points for a question like this
Answer:
71
Step-by-step explanation:
This is an arithmetic sequence with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here d = 2 - (- 1) = 5 - 2 = 8 - 5 = 3 and a₁ = - 1, so
= - 1 + (24 × 3) = - 1 + 72 = 71
The formula for this is A= a + b/2 x h.

Answer:
-7π/3 or -420 degrees
Step-by-step explanation:
So we know that the arrow has made one full rotation and that it is moving in a clockwise direction. So already we have -2π degrees.
The arrow stops at π/6 before the next π/2 rotation. Therefore we find the difference between the two.
π/2 - π/6
3π/6 - π/6 = 2π/6
π/3
Since this is still clockwise, we make this negative. So the measure of the angle shown by the arrow is -2π - π/3
