The total cost for sophia to build b birdhouses is represented by the function f(b)=3.5b+24. what does the value 3.5 represent in this situation? the total cost to build b birdhouses is $3.50. the initial cost is $3.50. for each birdhouse built, the total cost increases by $3.50. for each birdhouse built, the total cost decreases by $3.50.

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.

For each birdhouse built, the total cost increases by $3.50.

The number 3.5 multiplies b, so when b increases by 1, f(b) increases by 3.5. Making 1 more birdhouse increases the total cost by $3.50.

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
