Function notation Meaning
p(30) = 2500
A worker with 30 hours of training is paid $2500 a month
p(60) = 3000
A worker with 60 hours of training is paid $3000 a month.
The area of a square (in square feet) depends on the length of its sides
(in feet). This is written in function notation as a(s).
What is the best interpretation of a(3) = 9?

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

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
