Annette is late for work once every 3 days. Glenda her assistant is late for work once every 4 days. What is the probability that:
A) they are both on time?
B) Only one of them is on time?
Please ans
Need help on this. Any help is greatly appreciated.-since arc length = [angle / 360 ] * circumference
12 pi = [ 80 / 360 ] * 2 pi r
6= [ 2 / 9 ] *r
r = 27 inches ---answer-so you have to remember t
show that y is orthagonal to x_n and x_n---->x together imply x is othagonal to y
Note: an element x of an inner product space X is said to be orthagonal to an element y belonging to X if =0 similarl
I Want to find : Rank (linear algebra) with Gaussian Method!-Solving these in my head gives x = -4, y = -7, z = -5, so the rank must be 3. (if we can solve the equations fully like this, theyre indepe
Hello Experts,
Please answer my 2 questions with details:
1) How do I prove that x^3 - x^2 + x + 2 is prime in Z[x]?
2) And if I know that is prime ideal means that k was prime? Vice versa too?
The problem is -1x^5-5x^4-1x^3-9x^2-9x-0-The real zeros are:
x = 0
x = -5.08307062
x = -0.81919114
and also
x = 0.451131027 +/- 1.3992354976 i
How to find them?First of all, you can factor out the x
Use the mixed congruential method to generate a sequence of five 2-digit random integer numbers such that xn+1 = (41xn + 33) (modulo 100) and x0 = 48-Carrying out the sequence, we start with:

Hello Experts,
I have the polynomial in Z[x,y]:
f(x,y) = x^3 *y + x^3 - x^2 * y - x^2 +x*y + x +y^2 + 2*y + 2.
I need to prove its irreducible.
I want to use the Eisenstein Criterion where f(x,y) c

Ok, this is a question for all you math geniuses out there.
Ive been doing some research on mathematics, particularly into the area of very large numbers. I stumbled across some interesting things, s
Find the equation of the tangent line to f(x) = sqrt x at x=81 using the definition of a derivative.
Hint:f(x)= lim h approaching 0[f(x+h) - f(x)]/x-By definition,
f (81) = lim [ ( √(81+h) - √81 )
Thanks for the help.
I have an attempt. Im not sure if hyperbolic substitution is necessary but its the only way I could think of that would work.
∫ sqrt(x^2 + 2x - 3) dx
= ∫ sqrt((x-1)^2 - 4) dx
l
let u = [1+(x)^1/3]^1/2
and dx would be = 6u(u^2-1)^2 du
so your integral would look like:
∫ ( [6u (u^2-1)^2] / u ) du
= 6 ∫ u^4 -2u^2 +1 du
and you can do the rest :)-thanks for the BA!~
and do yo
