Answer:
Period =
The Ferris wheel will complete one round in 40 seconds.
Step-by-step explanation:
We have the function representing the height of the passenger by,
, where t = time in minutes.
It is known that when a function f(x) has period P, then the function a×f(bx+c)+d will have the period .
Since, the function has period , so the function h will have period i.e. .
Thus, the period of the given function is .
Now, as the period is minutes i.e 40 seconds.
Hence, we get that the Ferris wheel will complete one round in 40 seconds.
Answer:
To do this, you imagine a vertical (up and down) line moving across your graph from left to right. It should only be touching the line at one point at a time. If it is touching more than one point on the line at a time, the line is not a valid function. The first line and its inverse both pass the test.
Step-by-step explanation:
if there is more than 1 x u add the exes but you dont add the exes with the other numbers so in this case you would do 7 x 2/3 and you would leave the x alone
Answer:
so x = 20 , y = -21 , which is in quad IV
r^2= 400+441 = 841
r = √841 = 29
then cos Ø = 20/29
sec Ø = 29/20 = 1.45
