Find a function for my graph

I have two points on this graph. One is (1,0), the other is (0,∞). It looks like half a parabola or hyperbola. The x values range does not need to be just 1 to 0 - it may be drawn as 100 down to 0, bu

please help I have a test tomorrow and I need someone to explain this to me please!!!!!!!!!!!!! In triangle ABC, D is the midpoint of AB and E is the midpoint of AC. If BC=7x+1, DE= 4x-2 and the meas

Help with math hw (mathematicians needed!)

I need someone to solve the following problem.Please show and explain the steps to get the answer. 5-3(x-7(x-6) The value of x is not given so just write it in standard form.-5-3(x-7(x-6)) =5-3(x-7x

Calculus help please? :)

Use Riemann sums and limits to compute the area bounded by f(x)=15 x^3 + 6 x and the x axis between x=2 to x =8 Thank you!!-dx = (6/n) x(i) = 2+(6/n)i i = 0, n-->inf area = sum [i = 0, n] f(x(i)) dx

The straight line x+y=a will be a tangent to the ellipse x^2/9+y^2/16=1,if a is

1.8 2.+or-5 3.+or-10 4.+or-6-Any tangent to the ellipse x^2/9+y^2/16=1 is y=mx(+or-)sqrt(9m^2+16) [y=mx(+or-)sqrt(a^2m^2+b^2)] when m=-1 (slope of given line=-1) the equation becomes y=-x(+or-)sqrt(9+

Laplace transform problem

Find the inverse laplace of e^(-10s)/s(s^2+2s+2)-Ignore the exponential for a moment and do a partial fraction decomp on the rest. 1/[s(s² + 2s + 2)] = A/s + (Bs + C)/(s² + 2s + 2) ==> A =1/2 , B

Show that the sum E(k=1 to n) k! not equals to m^2 for any integer m, for n>=4. E means sigma.

plzz, i need help. i am going to select best answer.......-Suppose to the contrary that m^2 = 1! + 2! + 3! + 4! + ... + n! for some integer m. Reducing mod 5 yields m^2 = 1! + 2! + 3! + 4! + 0 (mod 5

Solve for x: (3/(x-2)) + (8/(x^2-4))=1

First, get a common denominator.When you factor x^2-4, you get (x+2) and (x-2), so you can multiply everything by these variables. 3(x+2)/((x-2)(x+2)) + 8/(x^2-4) = (x^2-4)/(x^2-4) Since the denominat

Math statistics question regarding min and max values

Find point c on the x-axis so ac+bc is a minimum with A(-3,2) and B(-6,-4)

Its on the x-axis so y = 0 A (-3 , 2) B (-6 , -4) C (x , 0) AC = sqrt((-3 - x)^2 + (2 - 0)^2) = sqrt(9 + 6x + x^2 + 4) = sqrt(x^2 + 6x + 13) BC = sqrt((-6 - x)^2 + (-4)^2) => sqrt(36 + 12x + x^2 +
