The function b(n) = 6n represents the number of light bulbs b(n) that are needed for n chandeliers. how many lightbulbs are needed for 15 chandeliers?
90 lightbulbs
2 lightbulbs
96 lightbulbs
80 lightbulbs

Option A is correct.

90 lightbulbs are needed for 15 chandeliers.

Step-by-step explanation:

Given: The function b(n) = 6n                  ......[1]

where n represents chandeliers and b(n) represents the number of light bulbs.

To find the number of light bulbs are needed for 15 chandeliers.

Substitute n = 15 in [1] we get;

lightbulbs

Therefore, 90 light bulbs are needed for 15 chandeliers.

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)
