Akio has a business taking care of dogs. She charges a registration fee of $10, plus $5 for each hour she works. Akio wrote a function to represent the total amount of money, in
dollars, she earned after x hours of working.
f(x) = ax + b

Step-by-step explanation:Given  that

f(x)=ax+b

so registration fee=b=$10

 Each hour fee=a=$5

where  x represnts hours

when

x=0

f(0)=5(0)+10

f(0)=10

f(1)=5(1)+10

f(1)=15

f(2)=5(2)+10

f(2)=20

and so on...

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
