A combination lock has numbers 0-49 on it. How many different 3-digit lock
Harman [31]

Answer:

19,600

Step-by-step explanation:

0-49=50 numbers

n=50

r=3

C(n,r)=n!/(r!(n-r)!)

=50!/(47!)(3!)

C(n,r)=C(50,3)

=50!/(3!(50−3)!)

= 19600

V125BC [204]

Answer:

  • E. 5.2 seconds

Step-by-step explanation:

Need to find the value of t, when h(t) = 0

  • -16t^2 +64t + 100 = 0
  • 4t^2 - 16t - 25 = 0
  • 4t^2 - 2*2t*4 + 16 = 41
  • (2t - 4)^2 = 41
  • 2t - 4 = √41
  • 2t - 4 = 6.4
  • 2t = 10.4
  • t = 5.2

Answer is 5.2 seconds
