Answer:
8,16
Step-by-step explanation:
Area = pi radius squared. (a=pi r squared).
the radius of this circul is 1.6 units so plunging that in you get 1.6 • pie = 5.02654824574. now square that. The answer is 15.7913670417.
Answer:
I think its the first one but not 100 % sure
Step-by-step explanation:
It is B because tangent lines are always perpendicular to radii
Answer:
F(t) = 10 +5t
Step-by-step explanation:
Income equals the initial fee plus the hours worked times the hourly rate
We know the initial fee = 10
hours = t
hourly rate =r
F(t) = 10 + r*t
We know a 5 hour job is 35 dollars
35 = 10 + r*5
Subtract 10 from each side
35-10 = 10-10 +5r
25 = 5r
Divide by 5
25/5 = 5r/5
5 =r
The hourly rate is 5
F(t) = 10 +5t
