Answer:
(a) 110 mm Hg
(b) 70 mm Hg
(c) 3/4 second
(d) see the attachment
Step-by-step explanation:
(a) The sine function has a maximum value of +1, so the maximum value of p is ...
pmax = 20·(+1) +90 = 20+90 = 110 . . . . . mm Hg
__
(b) The sine function has a minimum value of -1, so the minimum value of p is ...
pmin = 20·(-1) +90 = -20+90 = 70 . . . . . mm Hg
__
(c) The period of the sine function is 2π, so the value of t that makes the argument be 2π will be the period.
8π/3·t = 2π
t = 2π·3/(8π) = 3/4 . . . . . . multiply by the inverse of the coefficient of t
The period of her heartbeat cycle is 3/4 seconds.
__
(d) a graph is attached.
Answer:
31.46 km/hr to the nearest 100th
Step-by-step explanation:
10:55 to 11:00 is 5 min
11:00 to 12:00 is 60 min
12:00 to 12:38 is 38 min
That's 5 + 60 + 38 = 103 min = 103/60 hr. = t
d = rt
54 = 103/60(r)
r = 54(60)/103 =31.46 km/hr to the nearest 100th
