(a) suppose that a person has an average heart rate of 72.0 beats/min. how many beats does he or she have in 2.0 y? (b) in 2.00 y? (c) in 2.000 y?

A= 75686400

B= 7568640000

C= 75686400000

Step-by-step explanation:

1 day= 1440 min

1 year= 365 days

365 days*1440 min= 525600 min , 1 year= 525600 min

525600 min*2 years= 1051200 min

(in 2 years) 72 beats*1051200 min= 75686400

(in 200 years) 75686400*100= 7568640000

(in 2000 years) 7568640000*10 =75686400000

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
