Well, ok, the x intercepts aer where the function equals 0
also
if the x intercepts are r1 and r2 then the factored form of the function is
f(x)=a(x-r1)(x-r2) where a is a constant
well, we have it already in that form
f(x)=(x-3i)(x-3i)
the x intercept is at x=3i
standard form requires expansion
we expand to get
f(x)=x²-6i-9
Answer:
The answer for this question is Quadrant III
Answer:

Step-by-step explanation:
The upside down exclamation point(¡) denotes the subfactorial in math. There are two ways to approach solving the subfactorial, one being exact, while the other is a more practical approach.
One way (the mathematically correct way) is using the formula:
n=n!∑[(-1)^k]/k!, where k starts at 0 and counts to n.
However, another, less accurate way is simply ¡n = [n!/e], where the brackets mean to round to the nearest integer, which returns 2.25268983 * 10^(103)
Hope it helps :) and let me know if you want me to elaborate, or if the notation used was intended to be something else, as the subfactorial of 72 seems like an unnecessary amount of tedium.
Step-by-step explanation:
To find interest, multiply the principal (4000) by the rate (7%) and time in years (5).
I = Prt
I = (4000 * 5) * 7/100
I = 20000/1 * 7/100
Use cross cancellation (100 and 20000 have a GCF of 100)
I = 200/1 * 7/1
I = 200 * 7
I = $1,400
Kyle gets $1,400 in interest in this scenario.
