B: 80

All the sides add up to 20 so adding all four sides make 80

For each explicitly-defined sequence below, write the first few terms. Then use the terms to write a recursive equation.

Answer:

Step-by-step explanation:

Problem A

t(1) = 2(1) + 5

t(2) = 2*2 + 5 = 9

t(3) = 2*3 + 5 = 11

t(4) = 2*4 + 5 = 13

So this is the explicit result. Now try it recursively.

t_3 = t_2 + 2

t_3 = 9 + 2

t_3 = 11 which is just what it should do.

t_n = t_(n - 1) + 2

Problem B

t(1) = 3 * 1/2

t(1) = 3/2

t(2) = 3*(1/2)^2

t(2) = 3 * 1/4

t(2) = 3/4

t(3) = 3*(1/2)^3

t(3) = 3 * 1/8

t(3) = 3/8

t(4) = 3 (1/2)^4

t(4) = 3 (1/16)

t(4) = 3/16

So in general

t_n = t_n-1 * 1/2

For example t(5)

t_5 = t_4 * 1/2

t_5 = 3 /16 * 1/2 = 3/32

I need help with part a and b, please help

A. so the entire length of the to would be 25. You know 9 of those feet are not rope so you would subtract that from 25
25-9=16
16 would be the all the rope on top and you only want one side, so you would divide it by 2. The top right piece of rope would be 8ft long
Part b is the picture
