Joanne puts 40 bacteria in a Petri dish . The population of the bacteria is doubling every hour which function best represent the situation

Exponential growth ; y = 40 * 2^t

Step-by-step explanation:

The scenario above is best modeled using the exponential growth formula.

Since the number of bacteria increases; then it is a growth function.

Number doubles every hour, thus gives the rate of increase.

Exponential growth relation :

y = A(1 + r)^t

A = initial amount of bacteria = number of bacteria in Joanne puts in petri dish = 40

y = amount of bacteria after time t,

(1 + r) = 2

Therefore,

y = 40 * 2^t

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
