Answer:
Step-by-step explanation:
You'll need to find a way to share the graph or graphs associated with this problem.
The period is 4. The relationship between period and b (the coefficient of the independent variable of the cosine function) is (period) =(2π.b). Given that the period here is 4,
2π 2π
4 = ---------, and so b = ------- = π/2.
4
So now our y = a*cos (bx + c) becomes
π
y = 10*cos (------x + 0 + 10
2
The horizontal center line of this cosine curve is y = 10. The maximum value of the curve is 20, which is 10 + 10, and the minimum value is 0, which is 10 - 10.

Answer
137.385
Step-by-step explanation:
What is 6.5% of 129?
First, you have to change 6.5% to a decimal which is 0.065.
Then, you have to multiply 0.065 times 129 which gives you 8.385.
Finally, you have to add that amount to 129 which gives you $137.385, and that is the total cost of the prom dress
