Answer:

y = Asin (Bx)  + C

 

A = the amplitude  = 2

 

Frequency  =  1 /period

 

1 / (4pi)  =  1 /period

 

So...the period = 4pi

 

So

 

B  =  2pi / [ period]   =   2pi / [ 4pi]  =  2 / 4    =  1 / 2

 

C = the shift up/down....since we have a y int of (0,2)....the normal sine function is shifted up 2 units....so C = 2

 

So....the function is

 

y = 2sin ( (1/2) x) + 2

Greg has decreased his running time by 1/10 minute each of the last six weeks. Write an expression to represent the total change
Nastasia [14]

x is your starting running time. 1/10 of a minute is 6 seconds, so you can do x - 6(6). 6 times 6 = 36, so your answer is x - 36 seconds. 36 seconds.

I need help i forgot how to multiply decimals
Alekssandra [29.7K]

Stack the numbers on top of each other so the decimals are lined up. Get rid of the decimals and then multiply. Put the decimal point back in directly under where it was before
