**Need 8 grade math help quick please!**

there is only one number less than 2, and six possible throws. So, P(n<2) = 1/6 Similarly, P(n>=3) = P(n∊{3,4,5,6}) = 4/6 = 2/3 P(n≠4) = 1-P(n=4) = 1 - 1/6 = 5/6

I think you're right, Cassidy. It looks to me as though this document is Federalist and political. In this excerpt, Jackson denied the right of a state to annul a federal law. He states that it is destructive of the Union.

2 to the 2nd power is also a way of saying 2 times 2. So, 2 to the 2nd power is 4.

What is 2 to the 2nd power

**Math - PreCalc (12th Grade)**

I guess, though product is also involved lim(2x) = 2 * lim(x) But I guess C is closest.
*Thursday, March 20, 2014 at 1:25pm*

**Math - PreCalc (12th Grade)**

yes, that would be correct.

*Thursday, March 20, 2014 at 12:58pm*

**Math - PreCalc (12th Grade)**

So it is D?
*Thursday, March 20, 2014 at 12:51pm*

**Math - PreCalc (12th Grade)**

You are correct; you cannot divide by zero. So, f(x) is not defined for x=4. However, for any other value of x, f(x) = (x-4)(x+4)/(x-4) = (x+4) So, if you define f(4) = 8, then f(x) = x+4 for all values of x, and is now continuous.
*Thursday, March 20, 2014 at 12:43pm*

**Math - PreCalc (12th Grade)**

I chose C. Is that correct?
*Thursday, March 20, 2014 at 12:39pm*

**Math - PreCalc (12th Grade)**

What value must be defined for f(4) to remove the discontinuity of this function at x=4? f(x)=(x^2−16)/(x−4) A) 0 B) 4 C) -4 D) 8 E) -8 f(4)=(4^2−16)/(4−4) f(4)=0/0 you can't divide by zero. I don't understand the question.

*Thursday, March 20, 2014 at 12:29pm*

I believe it is A. But I'm not sure.

**Math - PreCalc (12th Grade)**

D If for no other reason, the sum of nth powers will be a polynomial of degree n+1.

**A Peculiar Question**

Is either a B+ or an A- considered a terrible grade? If I received a B+ for two essays that I was assigned and then an A- for another, will these grades ultimately cause a decrease in my GPA? I want to enter into either a film or art college, and I want to retain my 4.0 GPA ...

Ms.Sue I need your help

**Third Grade Math**

But doesn't kilo mean like small or somting like that
*Wednesday, March 19, 2014 at 9:26pm*

**A Peculiar Question**

A B+ is well above average, so it's a good grade. We can't know whether it will affect your report card because we don't know your other grades -- both in this class and in others.
*Wednesday, March 19, 2014 at 4:26pm*

**A Peculiar Question**

If I have been given a B+ for two essays, it is considered a terrible grade? Will it affect my report card?
*Wednesday, March 19, 2014 at 4:20pm*

**Math - PreCalc (12th Grade)**

Thank you!! you really are helping me alot.
*Wednesday, March 19, 2014 at 12:21pm*

**Math - PreCalc (12th Grade)**

Ummm. Do you not think it would be A? I explained how the discontinuity could be removed. Hence, it is removable.
*Wednesday, March 19, 2014 at 12:17pm*

**Math - PreCalc (12th Grade)**

Honestly, i don't get any of them..
*Wednesday, March 19, 2014 at 12:08pm*

**Math - PreCalc (12th Grade)**

start checking. How about showing some of your own ideas on further problems? I can do them - the goal is for you to work on them, eh?
*Wednesday, March 19, 2014 at 12:07pm*

**Math - PreCalc (12th Grade)**

So would it be none of the above?

What is the first natural number that causes the statement 1 + 3 + 5 +... + (2n − 1)<=4n − 1 to fail? A) 2 B) 3 C) 4 D) 5 E) 6
*Wednesday, March 19, 2014 at 12:05pm*

**Math - PreCalc (12th Grade)**

at x=5, f(x) = 0/0, or undefined. At any other value, though, f(x) = (x-5)(x+5)/(x-5) = x+5 So, f(x) is undefined only at x=5. By defining f(5) = 10, the discontinuity is removed. f(x) = x+5 for all x.
*Wednesday, March 19, 2014 at 12:05pm*

**Math - PreCalc (12th Grade)**

just start checking: 5^1 <= 4^1 + 3^1 5^2 <= 4^2 + 3^2 5^3 > 4^3 + 3^3

What is the first natural number that causes the statement:(2+3)^n<=4^n+3^n to fail? A) 1 B) 2 C) 3 D) 4 E) 5
*Wednesday, March 19, 2014 at 11:56am*

**Math - PreCalc (12th Grade)**

well, plug in x=2 and see what you get.

What is the right-hand limit of this function at x=2? g(x)=x^2−3/x−3 A) -1 B) 0 C) 1 D) 2 E) 3
*Wednesday, March 19, 2014 at 11:54am*

**Math - PreCalc (12th Grade)**

as x->3 from the left, (x-3) < 0, so |x-3| = -(x-3). -(x-3)/(x-3) = -1
*Wednesday, March 19, 2014 at 11:40am*

**Math - PreCalc (12th Grade)**

What is the left-hand limit of f(x)=|x−3|/x−3 as x approaches 3? A) 1 B) 2 C) 0 D) -1 E) -2
*Wednesday, March 19, 2014 at 11:14am*

**Math - PreCalc (12th Grade)**

As explained , C, D and E cannot be correct. A + B + C = 15000 A = B + C + 3000 3A + 2B + 2C = 30000 Solve these equations to get A, B and C
*Wednesday, March 19, 2014 at 11:12am*

**Math - PreCalc (12th Grade)**

I believe combined.
