Answer:
a) Sinusoidal functions are y = a sin [b(x-h)] + k (or)
y = a cos [b(x-h)] + k
Where a is amplitude a= (max-min)/2=(16-2)/2=7
period p= 2π/b
b=2π/30
Horizontal transformation to 10 units right h=10
k= (max+min)/2=(16+2)/2=9
h = 7 cos [π/15(t-10)]+ 9
b) t=10min=600 sec
substitue in the above equation
h=5.5m
5|8-x|
5|8-10|
= 5|-2|
= 5(2)
= 10
The value of the expression when x = 10 is 10.

Step-by-step explanation:
2x-5=15
2x=20
x=10
The rate of change is :
(2010 - 1780)/5 = 230 / 5 = 46
