The standard form of the sine is
y = asin(bx + c) + d
where | a | is the amplitude, period =
c is the phase shift and d the vertical shift
Here period = 15, thus
= 15 ( multiply both sides by b )
15b = 2π ( divide both sides by 15 )
b =
Answer:
Cristiano will have enough money to buy bike in 9 weeks.
Step-by-step explanation:
Given:
Cost of the bike = $189

Let the number of weeks be 'x'.
Now we can say that;
Money saved plus money saving each week multiplied by number of weeks is equal to cost of the bike.
framing in equation form we get;
