Question

A material has an initial quantity of 20 units. Which equation models the amount of the material, y, growing exponentially at a rate of 17% for time, X?
y = 20(1.17)x
y=20(2.7)x
y=20(0.83)x
y=20(17)x
y = 17(1.2)x

Answer 1

Y=17(1.2) you quantity is 20 so you move 2 decimals places over

Answer 2

y=20$2.7^{x}$ is the equation models that describes the growth rate of metal whose initial quantity is 20 units.

What is exponential functions?

It is inverse of the logarithmic functions.

How to form exponential function?

We have been given the initial quantity of metal which is 20 units

and it is growing exponentially at a rate of 17% for time x

So the required equation will be y=20 *e to the power x*17%

value of e is 2.718. so the equation becomes y=20(2.7)to power x
