(54.3+56.1+n)/3 = 55
54.3+56.1+n = 165
54.6 = n
Answer:
Step-by-step explanation:
Find the roots of x^2-25=0 by solving for x.
Add 25 to both sides
x^2=25
Square root both sides
x=-5
x=5
Answer:
a). f(0) = 4
b). f(6) = 8
Step-by-step explanation:
a). When x < 5, piecewise function to be considered,
f(x) = x + 4
Since, x = 0 is less than x = 5
f(0) = 0 + 4
f(0) = 4
b). When 5 ≤ x < 7,
Piecewise function to be considered,
f(x) = 8
Therefore, for x = 6,
f(6) = 8
In Sum: (2x - 2.1)+(2x - 2.1)+(2x - 2.1)
In Product form: (2x - 2.1) x 3

So, the initial number of bacteria in the culture = x
After 1 hour,
The number of bacteria = 185x/100
= 1.85x
After 2 hours,
The number of bacteria = (185 * 1.85x)/100
= 3.42x
So:
3.42x = 12500
x = 12500/3.42
= 3654.97
= 3655
From the above deduction, we can conclude that the initial number of bacteria in the culture is 3655.
