I need some help. I dont know how they came up with these numbers.
This site is very similar to my problem.
http://www.calculus-help.com/probs1999/2problem12.html

Just the top portion with the graph, and the solution under it.
How did they come up with these numbers in the solution
x = .8, 3.4, 4.4, and 6.2.
Can someone look at this and explain to me how they come up with their answers.

Suppose that an amount P_o(little case o) is invested in a savings account in which the interest is compounded continuously. The balance P(t) grows at the rate given by dP/dt=0.07P, where t is in years.

a. Write the function that models this situation. (Use function notation.)

b. How long will it take to have 150% of your original investment in the account? Round to the nearest year if necessary.
c. What is the doubling time for the account? Round to the nearest year if necessary.

lost on equation, any suggestions, help

Calculate how much work is required to launch a spacecraft of mass m from the surface of the earth (mass me , radius Re) and place it in a circular low earth orbit, that is, an orbit whose altitude above the earth's surface is much less than Re . (As an example, the International Space Station is in low earth orbit at an altitude of about 400 km, much less than Re=6380 km .) You can ignore the kinetic energy that the spacecraft has on the ground due to the earth's rotation.
Express your answer in terms of the variables m,me, Re and appropriate constants.

B)Calculate the minimum amount of additional work required to move the spacecraft from low earth orbit to a very great distance from the earth. You can ignore the gravitational effects of the sun, the moon, and the other planets.
Express your answer in terms of the variables m,me ,Re , and appropriate constants.
