x + 13 = 34
x + 13 - 13 = 34 - 13
x = 21
The area of the composite shape is approximately 180.53 square feet.
<h3>A sequence is defined by the recursive function then f(1) is 81</h3>
<em><u>Solution:</u></em>
Given that,
A sequence is defined by the recursive function:
------ eqn 1
Given that,

<em><u>Substitute n = 2 in eqn </u></em><em><u>1</u></em>

<em><u>Substitute n = 1 in eqn 1</u></em>

Thus f(1) is 81
