I understand that the option value is the intrinsic value + time value and if it is a out of the money call option there is no intrinsic value whatsoever however how is the intrinsic value determined overtime as it gets closer to the expiration date? The time value is based on how much time is left but does the intrinsic value determined by the traders or who?

So for example of a company is at $9 and the $10 out of the money strike price goes for $1.40 (so its $1 intrinsic and $0.40 for time value). What happens if the stock price goes to $11 or if it goes down to $8? I'm confused because I know that the intrinsic value is determined by the price of the stock but is there any way of calculating there that is going or is that completely just based on the market?

Thanks

The amount of radiation R(t) emitted from a solid decreases at a rate of proportional to the amount present, dR/dt = kr, where k is the constant of proportionality and t is measured in years. In 1900, the amount of radiation was 100 rads. By the year 2000 it has dropped to 75 rads. To the nearest year, when will 50 rads be emitted from the solid? (round k to the nearest thousandths)

Thanks a lot and it would be best if you show the work!

1. three years ago the average salary of junior executives at the ABC plant was $80,000 a year. The average salary of these executives has been increasing at a rate of (800 + 2100t^(1/2) [or square root]) dollars per year. To the nearest hundred dollars, find the average salary of junior executives at the ABC plant today?

The base of a solid is the region in the first quadrant bounded by x^2/a^2 + y^2/b^2 = 1. each cross section perpendicular to the x axis is an isosceles right triangle with the hypotenuse as a base. Find the volume of the solid in terns of a and b. Thanks!

The equation of the tangent to the circle x^2 + y^2 = 25 at the point (-3,4) is ___

3x-4y = 25 is the answer but I don't quite understand wh, can someone explain?

A wheel has angular position theta = 0 (radians) at t=0 (seconds). It then rotates with an angular velocity equal to .32 radians/sec. what is the average angular velocity from theta = 9 radians to theta = 16 radians in radians per second? If you can show work that would be greatly appreciated.

The point on the curve y=x^3 closest to the point (4,0) is

An airplane lands on a runway traveling 180 mph and begins to decelerate at a constant rate, taking 1/4 mile to stop. Find the length of time, in seconds, to cover the 1/4 mile. If you can also show it step by step that would be much appreciated!

I am wondering if there is someone who is able to help me and tell me how to get real time financial data to use for a python program. I know that the google finance api is already depreciated and the yahoo finance only allows data in CSV files. I am trying to create a python program that constantly updates the stock price to the real time quote. If someone can help me out that would mean a lot to me!

for a differentiable function the line tangent to the curve at x=a is used to approximate values of the function near x =a. If this technique over estimates the correct values, then the curve of the function at x=a is _____

a. negative

b. rising

c. falling

d. convave up

e. concave down

If you can also explain that would be greatly appreciated.

1. He not only executed the drawings for the company's patient applications but also designed an improved incandescent lamp.

Why is the correct answer "He not only" and couldn't it instead be replaced as Not only did he executed the drawings for the company's patient applications but also designed an improved incandescent lamp. ? Thanks for the help

It is a summation that starts at n =0 and goes to infinity. All the small powers go to n.

a. find values of x which make the series converge

b. if x=2, write the formula and find the sum of the series

c. find the 3 terms of the series

Thanks a lot for the help

The context of the problem is: A circular piece of sheet metal with a radius of 9 feet is to be used to form a right circular cone. If x represents the radius of the cone, what value for x would maximize the volume of the cone?

So I find the height which is root(9^2-x^2)

volume is = 1/3pix^2*root(81-x^2)

The problem is here as well
