What is the period of the sinusoidal function?

(I need this as soon as possible!)

The period of the sinusoidal function is 4.

Step-by-step explanation:

In order to find the period, we can use below definition of period.

The time requires to complete a full cycle is called period. In other words, the length of a complete cycle is called period.

From the given figure, we can see that the sinusoidal function the length of a complete cycle is 4.

Therefore, the period of the sinusoidal function is 4.

the answer is 5/3x+7/5y+7

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
