Answer: For each birdhouse built, the total cost increases by $3.50.
Step-by-step explanation:
Given: The total cost for Sophia to build b birdhouses is represented by the function
We can see in the function 3.5 is multiplied to b, so when b increases , f(b) increases by 3.5.
and
Therefore, the value of 3.5 represents that for each birdhouse built, the total cost increases by $3.50.

Answer:
B
Step-by-step explanation:
<u>Answer</u>
a. r^n=a
c.^n√a=r
<u>Explanation</u>
<u><em>solution 1</em></u>
a⁽¹/ⁿ⁾ = r
Powering both sides of the equation by n;
a⁽¹/ⁿ ₓ ⁿ⁾ = rⁿ
<em>a¹ = rⁿ </em>
<u><em>solution 2</em></u>
Also,
a⁽¹/ⁿ⁾ = r
a⁽¹/ⁿ⁾ = ⁿ√a <em> (nth root of a)</em>
<em>ⁿ√a = r</em>
