To find the answer, we need to see by how much 20 changed to 30.
20 (1.5) = 30
So that means that
9 (1.5) = 13.5
Answer:
8
Step-by-step explanation:
Calculate the distance d using the distance formula
d =
with (x₁, y₁ ) = z₁(6, 2) and (x₂, y₂ ) = z₂(6, 10)
d =
=
= = 8
Answer:
Period =
The ferris wheel will complete one round in 40 seconds.
Step-by-step explanation:
We are given the function representing the height of the wheel by,
where t = time in minutes.
Now, we know that if a function f(x) has period P, then a×f(bx+c)+d will have the period .
Since, the function has period , thus the function h will have period i.e. .
Therefore, the period of this function is .
Now, since the period is minutes i.e 40 seconds.
Hence, we get that the ferris wheel will complete one round in 40 seconds.
The exact number is 121.966019, so if you round to the nearest whole number, the answer is 122.
