440000 because the decimal is positive you move the decimal place five places to the right.
Answer: D. 21ways.
Step-by-step explanation:
This is based on selection, fixing two '3' numbers into 5numbers to make it 7 numbers can be done in 7C2 ways.
Generally, nCr = n!/(n-r)!r!
7C2 = 7!/(7-2)!2!
=7!/5!2!
=7×6×5!/5!×2!
=7×6/2

We can find roots by setting f(x) = 0 --> x^4 - x^3 - 13x^2 + x + 12 = 0.
Factoring f(x) to make things easier for us gives us (x - 1)(x + 1)(x - 4)(x + 3), which, equal to 0, gives us the ability to set each set of parentheses = 0.
x - 1 = 0 gives us x = 1.
x + 1 = 0 --> x = -1.
x - 4 = 0 --> x = 4.
x + 3 = 0 --> x = -3.
our roots are x = 1, -1, 4, and -3.
1 14'th as a decimal would be 1/14 or 0.0714 (rounded to the nearest ten thousandth)
Answer:
f(8) = 195
Step-by-step explanation:
When the x if f(x) is replaced with an 8, this just means that it is the eighth term. All you really have to do is replace every X in the function to find the answer.
f(8) = 3 + 3(8)²
f(8) = 3 + 3(64)
f(8) = 3 + 192
f(8) = 195
Hope this helps!
