Hi there!

f(x) = 2(1/5)ˣ
Recall the form of an exponential function:
f(x) = a(b)ˣ where:
a = initial value
b = rate of decay/growth
If b > 1, the function is undergoing exponential growth. If b < 1, then the function is undergoing exponential decay.
1/5 < 1, so the function is undergoing exponential decay, not growth.
Answer:
D. difference of squares
Step-by-step explanation:
Both of the terms x^2 and 9 are squares, so their difference is the difference of squares. The factorization of that is a "special form" that can be usefully memorized.
a^2 -b^2 = (a -b)(a +b)
x^2 -9 = (x -3)(x +3)

Step-by-step explanation:
Answer:
$870
Step-by-step explanation:
To figure out how much the final value here is, use the formula A = P(1 + rt). (A = total accured amount, P = principal, r = rate (%), t = time (years))
A = 600 * (1 + (10 * 9/200)) (multiply 10 by 9 and put that over 200)
A = 600 * (1 + (90/200)) (90/200 simplifies to 9/20)
A = 600 * (1 + (9/20)) (add 1 (20/20) to 9/20 to get 29/20)
A = 600 * 29/20 (Multiply 600 by 29 and put that over 20)
A = 17400/20 (Divide 17400 by 20 to get 870)
A = 870
$870 is the final value.
