The circumference follows the formula
C= 2 (pi)R
R is the radius which is half the diameter when we put this into the equation we get
C = 2 (pi)(4.5)
C=28.274334
Answer:
umm that doesn't make a whole lot of sense if its multiple choice can you give us the options please sorry I couldn't answer
Step-by-step explanation:
Answer:
Step-by-step explanation:
Looking at the arrows on the graph, it appears that as the graph keep growing UP unbounded, it also keeps growing to the left unbounded (to negative infinity, to be exact). Looking to the right, it appears that as the graph decreases unbounded (the y values keep getting smaller), the graph keeps growing in the x direct to positive infinity. So the domain is
- ∞ < x < ∞
Realistically would be 20.
Let f be the function with variable n, which gives the number of pictures left in the phone after deleting pictures for n-days.
So f(1) gives the number of photos left after 1 day of deleting photos
f(2) gives the number of photos left after 2 days of deleting photos
and so on.
f(1)=745-20
f(2)=745-20-20=745-20*2
f(3)=745-20-20-20=745-20*3
so clearly f(n)=745-20n
Answer:
the algebraic expression is f(n)=745-20n,
where n is the n'th day of deleting photos, and f is the number of photos left after n days of deleting.
