Which of the following situations would be modeled by an exponential growth function? 1.)the total cost of a long-distance phone call which charges $0.10 per minute

2.)the amount of a radioactive element remaining as it decreases over one year

3.)total amount of snowfall from a storm with a snowfall rate of 2 inches per hour

4.)the total amount earned after investing $1000 in a account at 5% growth each year

answer: 43/157

this is the answer and if you try to prove me wrong your a meanie

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

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
