your bike lock has 4 digits numbered 0-9. Find the total number of possible combinations for the lock.

Answers

Answer:

10,000

Step-by-step explanation:

With a bike lock, you can usually use the same number more than one... you can have them the same (7777) if you want.

So, you have 10 possibilities for the first digit, 10 again for the second digit, 10 for the third digit... and also 10 for the last digit.  So...

10 * 10 * 10 * 10 = 10,000

Diego drops his camera as he climbs a hill and it falls to the ground 256 feet below the distance D that the camera falls in T seconds is given by the equation D=16t2 how long does it take The Camera to hit the ground

Answers

Given that Diego drops his camera as he climbs a hill and it falls to the ground 256 feet below the distance D.

to solve the time it hit the ground, use the given equation
D = 16t^2

t^2 = d /16

t = sqrt( d / 16)

t = sqrt( 256 / 16)

t = 4 second
after 4 s the diego's camera will hit the ground
