Answer:
The ratio of the areas will be will be 1 : 9
Step-by-step explanation:
The linear scale factor represents a ratio that is used to multiply the dimensions of objects so that accurate geometries can be transferred between real-life and paper.
The linear scale factor is quite different from the area scale factor but related to it in the following way:
The area factor can be obtained by squaring the linear scale factor.
This is Area factor = (Linear scale factor) ^2.
Linear scale factor = (1:3)
Area factor = 
Area factor will be 1: 9
Thus, when the linear scale factor is 1:3 the area factor will be 1 : 9
10/3 goes where 3 and 1/3 is.
This is because 10/3 as a mixed number is 3 and 1/3.
17/3 is where 5 and 2/3 is. Do the same thing as before.
Hope this helps!
24 degrees per second is 360 degrees in 15 seconds (pretty fast for a Ferris wheel!).
a) The distance above the ground can be modeled using a cosine function.
.. h(t) = 7 -6cos(2πt/15)
b) h(t) = 10
.. 10 = 7 -6cos(2πt/15)
.. (10 -7)/-6 = cos(2πt/15)
.. 2πt/15 = π ±π/3 +2kπ
. t = 7.5*((1 ±1/3) +2k) . . . . . . . . seconds; k = any integer
You are 10 meters above the ground at t=5 seconds and every 15 seconds thereafter, as well as at t=10 seconds and every 15 seconds thereafter.
