Can someone help me in this exercise, it is about functions. Thank you
1 answer:
Answer:
a)
Since the radius of the balloon increases by 5 cm every second, the amount of time passed in seconds multiplied by 5 will give us the radius at any given point in time
So, f(t) = 5t
b)
Since the surface area of a sphere is 4 (r)^2
We already have the radius of the sphere at any given time from our first equation
SA(t) = 4 (5t)²
Kindly Mark Brainliest, Thanks!

The given equation is a wave function. When plotted, the graph is shown in the attached picture. However, the unit is in degrees instead of radians. A unit of π is equivalent to 180°. This plot could determine one variable if the other is given.
