Answer:
x = 3
Step-by-step explanation:
It should NOT be "fight of the origin", rather "right of the origin".
Now let's move on to solve the question...
The x-intercept is found by setting the function equal to 0. Thus:
0 = x^3 - 9x
<em>Let's solve this using algebra:</em>

<em>Hence, x = -3 and x = 3</em>
<em />
The coordinate that is to the right of the origin is the positive one, so x = 3 is the x-intercept we are looking for.

Answer:
$282.98
Step-by-step explanation:
For computing the principal amount we need to apply the present value function i.e to be shown in the attachment below:
Data provided that in question
Future value = $25,000
Rate of interest = 9%
NPER = 13 years × 4 quarters = 52 quarters
PMT = $0
The formula is shown below:
= -PV(Rate;NPER;PMT;FV;type)
So, after applying the above formula, the present value is $282.98
