We are told that f(1) = -1.5, and that f(n+1) = -2f(n).
Then: f(2) = -2f(1) = -2(-1.5) = +3 (answer)

The volume of air inside a rubber ball with radius r can be found using the function . What does represent?

d1i1m1o1n [39]

Since in this problem, we are dealing with a balloon we can now say that the container or the shape we are dealing with is a sphere. The volume of a sphere is $V = \frac{4}{3} \pi r^{3}$ hence the volume is directly proportional to the radius. The volume increase by a factor of $r^{3}$

Speed was increased 20% to 48 mph. What was the speed before the increase

grigory [225]

Answer:

40 mph

Step-by-step explanation:

If the speed increased by 20%, now the speed is 120% of the original speed.

48 mph is 120%, so dividing by 6 will get 8 which is 20%.

If 8 is 20%, you can multiply it by 5 to get 40, which is 100%. This means 40 mph is the original speed.

Hope this helps!
