What is an example of something 12 inches around

Its a pretty simple question.-A 2 liter bottle-A 12 inch around circle-a circle

Managerial Calculus (An object shot into the air from a position )

An object shot into the air from a position on the edge of a cliff next to the sea moves so that its height above sea level at time t seconds is given by the formula s(t) =-16t^2 + 80t +96 where s is

How do you factor this equation

I really, really dont get this stuff. The equation is -3m^2+48n^2 The ^ stands for to the power of (since I cant actually make it go up...). I know to make it: -1(3m^2-48n^2) To take out the n

How to prove n+k'=(n+k)' where k' is the successor of k, and n is a natural number

(n+k) is the successor of (n+k)-The successor to any natural number is defined to be that number obtained by adding 1 to the natural number in question. Thus k +1 is the successor to the number k, and

How to prove 1/(secx+1)=cotx(cscx-cotx)

1/(secx+1)=cotx(cscx-cotx) and 4/(csc^2x+sec^2x=sin^2 2x)-1)1/(secx+1) = cotx(cscx-cotx) R.H.S. = cotx(cscx-cotx) = (cosx/sinx)[1/sinx -cosx/sinx]R.H.S. = cosx(1-cosx)/sin^2x = cosx(1-cosx) / (1-co

Do do I find Interval of convergence for this problem

I have f(x) = x^2/(1+x^3) I got the summation of sigma( n= 0 to infinity) (-1)^x (x^(3n+2)) how do I find the interval of convergence for that? I only learned that the ratio test only apply in sit

A remainder theorem question.

Im doing this question as part of some AS Maths revision, and keep getting -10 although apparently the answer is -3. The remainder when 2x^3 + ax^2 + 4 is divided by x-2 is five more than when it is

What two numbers multiply to 1640 and combine to 1

this is one of the questions on my take home test i need help. please help me.-By combine Im guessing you mean subtraction, because no other simple operation makes sense. x * y = 1640 x + 1 = y x(x+

Need help. EASY questions. Well easy for you not me obviously lol

What type of graph would you use for this? What type of graph would best show the growth in the numbers of people owning cell phones from 2000 to 2007? A. line graph B. double-bar graph C. circle grap

X^2+2x=2e^7 .............

Original Problemln(x/2)+ln(x+2)=7 Got through the first few steps, stuck on what to do next at x^2+2x=2e^7 (just simplify, in terms for x)-x^2+2x=2e^7 Rewrite in standard form: x^2 + 2x - 2e^7 = 0

Is the function below a polynomial function? If so, how to find the degree? leading coefficient? &.....

Constant coefficient? g(x)=4x^5+7x-5/9x^4-Yes, its a polynomial. The degree is just the highest exponent of the polynomial so in this case, its 5 because of 4x^5. The leading coefficient is the numbe

Suppose that f(x) = ax + b, where a and b are real numbers.

Suppose that f(x) = ax + b, where a and b are real numbers.Given that f(f(f(x))) = 8x + 21, what is the value of a and b? Steps please-a(a(ax + b) + b) + b = 8x + 21 a((a^2)x + ab) + b) + b = 8x +

9th grade math help - 2 questions on rotating/reflecting shapes on a graph please

Im not too sure how to do this: find the coordinates of the vertices of each figure after the given transformation. 11. rotation 180 degrees about the origin. E(2, -2), J(1, 2), R (3,3) S (5,2) 12.

Statistics. Why we never "accept" the null hypothesis

So this question has been bugging me, this is my answer and all I got was a why not? marked in red at the end. We never accept the null because our goal is to reject it. With sufficient evidence we a

Proof with Complex Variables

Let f(z) be entire and let |f(z)| ≥ 1 on the whole complex plane. Prove that f is constant-Just consider 1 / f(z), and use Liouvilles theorem. ----- I tried Liouvilles thereom but that only applies
