0.3
Step-by-step explanation:
the base must be raised
for example
55 = n ( the base is 10 ), then
55 = 
Step-by-step explanation:
Rate of growth equals 420/100 = 4.2 times per hour
So after t=three hours,
size of culture = 100*(4.2)^t = 100*4.2^3=7408.8 bacteria,
round to nearest unit 7409 bacteria after three hours (after initial size of 100).
Answer:
B.) 2 3/4 + (-4 1/4) = -1 2/4
Step-by-step explanation:
blue line: forward with positive +
red line: backward with negative -
so the number line follows: + - = -1 2/4
Step-by-step explanation:
2y=14
y=7
-2x-2(7)=-28
-2x=-28+14
-2x=-14
x=7
