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
2(x+5)2+8x+5+6=0 is the answer
The answer is 26.36. If you were trying to figure out what is 25% of 6.59, you'd have to multiply, however you need to know what 6.59 is 25% of so you do the opposite, just divide 6.59 by .25 and you'll get 26.36 which is your answer.
Answer:
14 9/10
Step-by-step explanation:
2 2/7 times 2 = 4.57
5 1/6 times 2 = 10.33
10.33 + 4.57 = 14.90
14.90 as a fraction is 14 9/10
