Let us assume the initial number of bacteria in the culture = xAfter 1 hour,The number of bacteria = 185x/100 = 1.85xAfter 2 hours,The number of bacteria = (185 * 1.85x)/100 = 3.42xSo3.42x = 12500x = 12500/3.42 = 3654.97 = 3655From the above deduction, we can conclude that the initial number of bacteria in the culture is 3655.
You practically answered this one yourself by giving some of the equation we need already filled in. It would look like this: A(t)=500(1.04)^7. Start by taking 1.04 to the power of 7 to get A(t)=500(1.3159). Finish by multiplying to get
A(t)=$657.97
Answer:
7r^2-64r+64

-15r+64
Step-by-step explanation:
-3/2
Down 3
Right 2
As an improper fraction it would be -1 1/2
Hey! Slope is the coefficient of the x variable: in this case: -6.75.
The y- intercept is the value when x = 0 (also the number without the x variable on it), which is 8.54.
Hope this helps!
