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
Answer:
The answer would be D
Step-by-step explanation:
To find how many Katie has, you would have to double it ( times by 2 ). Then subtract 3, since Alejandro has three less than twice as many as Katie.
Answer:
Step-by-step explanation:
has the form 
known as a difference of squares. It factors into (a+b)(a-b). To find a and b you take the square root.
The factored for is (a+b)(a-b).
In this case, it is
Since,
r = 35 inches & Circumference = 2πr
Therefore,
C = 2 * 22/7 *35
C = 2 * 110
C = 220 inches
Therefore, half the distance covered = 110 inches
Since, 109.9 is closest to 110
Therefore,
The correct option is 'C'
