The number of people that enter a contest the 1st day is 27. The 2nd day 31 people enter and 35 enter on the 3rd day. This pattern continues and the contest lasts 14 days.

What is the total number of people that enter the contest? Write the arithmetic series formula you used to determine the total number of people and show all the steps to find the solution

742

Step-by-step explanation:

27 + 31 + 35 + ...

a = 27

d = 31 - 27 = 4

S14 = (14/2)[2(27) + (14-1)(4)]

= 7(54 + 52)

= 7(106)

= 742

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
