The constant of proportionality is 5/9
y= kx where k is the constant of proportionality
y = 5/9 x
k = 5/9
Answer:
The practical domain for the function f(x) will be [0,5].
Step-by-step explanation:
A model rocket is launched from the ground and its height from the ground is given by f(x), t seconds after its launch.
It is given that the rocket reaches maximum height at t = 2.5 seconds and comes back to the ground after t = 5 seconds.
So, at t = 0 seconds, the rocket was at the ground and hence, t can not be negative and after t = 5 seconds the rocket comes back to the ground and hence, t can not be greater than 5 seconds.
Therefore, the practical domain for the function f(x) i.e. the values of t lies in the interval [0,5]. (Answer)
Answer:
It is greater because 3.6 is less than 9 and 3,6 is greater than1
Step-by-step explanation:
Answer:
A = 907.46 
Step-by-step explanation:
C = πd
34π = πd
d = 34
r = 17
A = 
= 3.14(
) = 3.14(289) = 907.46
