If ISO 400, SS 30, f/5.6 overexposes a picture three stops, what are the correct settings for a good exposure?

Answer:

  ISO 1600

Step-by-step explanation:

"Three stops" means the picture is overexposed by a factor of 2^3 = 8. Each f-stop increase halves the exposure, so increasing from 5.6 through 8 to 11 means you have cut the exposure by a factor of 4 with the f-stop change.

Each halving of the shutter-open time also cuts the exposure in half, so reducing the shutter speed from 1/30 to 1/250 cuts the exposure by a factor of about 8.

The adjustments of shutter speed and f-stop have decreased the exposure by a factor of 4·8 = 32, which is a factor of 4 more than the factor of 8 you needed. (The shutter speed change by itself would have been sufficient.)

So, to compensate for the much smaller exposure, you need faster film, by a factor of 4. The film needs to go from ISO 400 to ISO 1600.

vitfil [10]

Answer:

100/2048=0.048828125%

Step-by-step explanation:

He has a 50% chance of making each free-throw, so 1/2*1/2*1/2*1/2*1/2*1/2*1/2*1/2*1/2*1/2*1/2=1/(2^11)=1/2048

to get a percentage you time by 100 to get 100/2048

A polynomial has zeros x=0, x= -3, X = 4. What are some possible factored equations for this fourth degree polynomial.
kati45 [8]

Answer:

x^{2} (x + 3)(x - 4)

Step-by-step explanation:

You can multiply this out to get the full equations.

It's to the 4th degree so the x on the outside has to be squared to add the fourth degree.

To get other zeros:

x + 3 = 0

x = -3

x - 4 = 0

x = 4

Hope this helped. :0)
