You invest $850 into a stock market fund, which grows at a rate of approximately 4% each year. Write an equation that can be used to calculate the amount of money in the fund after x years

We have been given that you invest $850 into a stock market fund, which grows at a rate of approximately 4% each year. We are asked to write an equation that can be used to calculate the amount of money in the fund after x years.

We will use exponential growth formula to solve our given problem.

An exponential function is in form , where,

y = Final amount,

a = Initial amount,

r = Growth rate in decimal form,

x = Time.

Let us convert 4% into decimal.

.

We have and , so our equation would be:

Therefore, the equation can be used to calculate the amount of money in the fund after x years.

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

3/6   and 9/18
