how about if the unkown is in the exponent like.. 1.06^t = 2(1.04)^t t? 1.08^-n + 1.08^-2n = 1 n?

is it possible?

without using a calculator's graphing or equation solver tools :-p 2000x^16 + 5000x^39 = 3000 + 1600x^12 how can i solve for x? 200(1+i)^7 + 100(1+i)^5 = 300(1+i)^3 i? 1.06^t = 2(1.04)^t t? 1.08^-n + 1.08^-2n = 1 n? 6x^2-2x-3=0 argh why can't i do these.. i feel like I am...

thanks all its making a lot more sense after you have integrated an integral, what do you do with it to 'solve' it using the upper and lower limits? for example, in the example the answer is e^ln(1+t) from 0 to n.. how can i solve this now?

what does "dx" mean?

i can guess my way through basic elementary integrals

I have no idea what this means... Im taking a economics class and its been 4 years since I did any calculus work, and I am completely in awe at what I am looking at here What do the symbols mean? How do you go from step 1 to step 2 to step 3? This is one tiny tiny bit of my course but...

Three fire hoses are connected to a fire hydrant. Each hose has a radius of 0.020 m. Water enters the hydrant through an underground pipe of radius 0.080 m. In this pipe the water has a speed of 3.0 m/s. (a) How many kilograms of water are poured onto a fire in one hour? (b) Find the water speed...

Pressure on a roof (help!) A house has a roof (colored gray) with the dimensions shown in the drawing. Determine the magnitude and direction of the net force that the atmosphere applies to the roof when the outside pressure rises suddenly by 10.0 mm of mercury, before the pressure in the attic...
