Using technology, we determined that mary’s investment account can be modeled by the function, m(x) = 4.96(2.18)x in thousands of dollars. what was mary’s initial investment?

$4960.

Step-by-step explanation:

We have been given that Mary’s investment account can be modeled by the function, in thousands of dollars. We are asked to find Mary's initial investment.

We can see that the given function is an exponential function where, initial value is 4.96 and growth factor is 2.18.  

Since the function given Mary's investment in thousands of dollars, so we need to multiply 4.96 by $1000.

Therefore, Mary's initial investment was $4960.

step-by-step explanation:

abc

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
