A shoreline observation post is located on a cliff such that the observer is 280 feet above sea level. The observer spots a ship

morpeh [17]

Answer:

Step-by-step explanation:

a) D/280 = tan(90 - 6)

D = 280tan84 = 2,664 ft

b) D/280 = tan(90 - 16)

D = 280tan74 = 976 ft

ship speed = (2664 - 976) / 43 = 39.2 ft/s

A person’s theoretical maximum heart rate (in heartbeats per minute) is 220 - x where x is the person’s age in years (20 ≤ x ≤ 6

Lyrx [107]

Let f(x) represents the heart beat of the person.

Now, we have been given that person’s theoretical maximum heart rate is given by 220 - x.

Also, we have been given that person strive for a heart rate that is at least 50% of the maximum. At least means greater than equal to.

Thus, we have

$f(x)\geq (220-x)0.5\\
f(x)\geq 110-0.5x$

Also, we have been given that person strive for a heart rate that is at most 75% of the maximum. At most means less than equal to.

$f(x)\leq (220-x)0.75\\
\\
f(x)\leq 165-0.75x$

Therefore, the system of inequality is given by

$f(x)\geq 110-0.5x\\
f(x)\leq 165-0.75x$
