Using technology, we found that juan’s investment account can be modeled by the function, c(x) = 3x2 - 2x + 5, in thousands of dollars. what was juan’s initial investment?

$5000

Step-by-step explanation:

We have been given that Juan’s investment account can be modeled by the function,

In order to find Juan's initial investment, we substitute x = 0

On substituting x=0 in the given model,

Now, it has been given that investment is in thousands of dollars.

And we got C(0) = 5.

Therefore, the initial investment was $5000

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
