Answer:
56
Step-by-step explanation:
Keep the order of opperations in mind when doing this (PEMDAS). First, solve what is inside the parentheses (6-1). Then, solve the exponent and the multiplication (6² and 5×5). Finally, finish adding and subtracting to get the answer.
-13v=195
divided each side by -13: v = -15
I=prt. I=375x .035x 4. I= 8.85x4. I=35.42
Answer:
The size of the sample after four hours is of 3158 bacteria.
Step-by-step explanation:
The population after t hours can be modeled by the continuous exponential growth model, which is:
In which P(0) is the initial population and r is the growth rate paremeter.
A growth rate parameter of 17% per hour.
This means that
Suppose also that a sample culture of 1600 is obtained from this population.
This means that
Find the size of the sample after four hours.
This is P(4).
Rounding to the nearest integer
The size of the sample after four hours is of 3158 bacteria.
1. so just subsitute numbers if we subsitute 5 for x then we get 0 if it's height is 6 then the time will be 16
2. so you want to factor the equation and get f(x)=x^2-4x-5=(x-5)(x+1) then set this equation = to 0 so (x-5)(x+1)=0
x-5 or x+1 must equal 0 so
x-5=0
x=5
x+1=0
x=-1
discard this because you cannot yield a negative ammount
so when the bank yields 5 in a day, the income is 0
