Prove Bernoulli's inequality via induction

(1 + x)n ≥ 1 + nx I can work it down to this step but I have no idea where to go from here to finish the equation. (1 + x)^k (1 + x) ≥ 1 + x + kx + kx2-Looking at the inductive step (youre very clos

X^2 - 6x = 0.5x + 42 ... solve for x

Steps please! Thanks in advance!-x^2 - 6x = 0.5x + 42 x^2 - 6.5x - 42 = 0 2x^2-13x - 84 = 0 (2x-21)(x+4) = 0 x = 21/2 or -4 x = 10.5 or -4-1. Click the windows button. 2. Click All Programs. 3. Click

Math Problem - About 4 circular Silo's and their Volume...

Four Circular wheat silos are arranged so that each circular silo touches two other silos at exactly one point. (So basically the Silos are arranged in 2 rows of 2) When the silos are filled, the grai

Maths Problem: Help this Shepherd solve his grass problem

A shepherd found that his cow & goat would eat all the grass in a certain field in 45 days, that his cow & donkey would eat it in 60 days, but that it would take his goat & donkey 90 days to eat it al

General formula for a second derivative

Im struggling trying to find the second derivative of f(x)=x^4*e^x Ive found f (x)= e^x*x^3(4+x) using the product rule. Im not very good with the dy/dx notations yet and have been using u, v, u

How many meters are in a kilometer

1000 (kilo = one thousand)-In engineering notation kilo is 1,000 (3 decimal places 10^3), mega is 1,000,000 (6 decimal places 10^6), giga is 1,000,000,000 (9 decimal places 10^9), etc. So, for instan

0.001869 = tanx + tan^2x

Solve for x please, I simplified to that from 1800 = 2500tanx - 490(1+tan^2x). I think I simplified correctly, but if not solve from the original equation please.-—————————————————————————————————————

How to find the slope and the intercepts of this line algebra(i give best answer in 1 hour)

f(x)=4/5x+7-slope=m=4/5 (0,7) then to find x-int you have0=4/5x+7 -7=4/5x -35/4=x or x= -8 3/4 so (-8 3/4,0)-think of f(x) as being y the slope is the x-intercept the y-int is (0,7), because that is

Imaginary numbers (beginners)

How do I solve this? 2/(3-i) I know you rationalize the denominator, but thats where I got stuck.. please and thank you!-2/ (3-i) first you multiply the numerator and denominator by (3+i) u get

How many meters are in .23 of a mile

1 mile is equal to 1609.344 meters 23/100 = x/1609.344 100x = 37014.912 so, x = 370.14912 meters

Use squeeze theorem to find the limit as x approaches 0 of sin(1/x) and lim x->0 x sin (1/x)

lim(x→0) sin(1/x) does not exist, because x→0, sin(1/x) oscillates more frequently between -1 and 1 inclusive (so there is no unique limit). We can show this sequentially: Pick two sequences {1/(πn)}
