0.17
Step-by-step explanation:
The function can be rewritten as ...
B(t) = 9300·((1/2)^6)^t = 9300·(1/2)^(6t)
In order to multiply the number of bacteria by 1/2, the value of the exponent 6t must be equal to 1:
6t = 1
t = 1/6 ≈ 0.166667 ≈ 0.17
The culture loses half its size every 0.17 seconds.

Answer:x=2, y=1, z=-1
Step-by-step explanation:
Given
2x+y+z=4----1
x-y+3z=-2----2
-x+y+z=-2----3
Add 2 & 3 we get
4z=-4
z=-1
Put value of z in 1 & 2
2x+y-1=4
2x+y=5----3
x-y+3(-1)=-2
x-y=1------4
add 3 & 4 we get
x=2
Put x & z in 1
y=1
