Tomtit [17]

Answer:

Total tape used by marge is 6 inches .

Step-by-step explanation:

As given

marge cut 16 pieces of tape for mounting pictures on poster board.

Each\ piece\ of\ tape\ was\ \frac{3}{8}\ inch\ long.

Total tape marge uses = Number of pieces × Each piece length

Total\ tape\ marge\ uses = \frac{16\times 3}{8}

Total tape marge uses = 2 × 3

how to find the period, amplitude, and vertical shift of a sinusoidal graph. please explain in the simplest way possible, tyyyy
Kay [80]

Answer:

Step-by-step explanation:

a) period is the length of one cycle  ( one full squiggle ) If you are lucky and the graph is on exact numbers.. at a high point and to the next high point.. then just take that horizontal distance,  that's one period  also if it's not  you could find the period, T,  by using  T = 2pi / k    where k is a number that represents how fast , or how many times the wave cycles in one second or some other amount of time.  

b) Amplitude is a number that goes right before the sinusoid, which is multiplied by it because,  sin , cos,  are at max 1 or at min -1  

c)  vertical shift is what is added , for upwards shift... before or after the                      sinusoid  ie  sin , cos,  ect ect.

does this help?
