An arithmetic sequence is described by the function f(n)=-3n+7. Determine the first five terms of this sequence.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

3; 9 is 8 to -4

step-by-step explanation:

might be the correct answer will be question number 2

prime

the number 37 is prime
