To begin a bacteria study, a petri dish had 1800 bacteria cells. Each hour since, the number of cells has increased by 15%.
rodikova [14]

Answer:

The exponential function is C(t)=y(b)^t\ Or\ C(t)=1800(1.15)^1

Step-by-step explanation:

Given

t be the number of hours.

y number of bacteria cells.

And we know that an exponential function is C(t)=y(b)^t,where b is a positive real number, and in which the argument t occurs as an exponent

The petri dish has 1800 bacteria cells we can say that y=1800

In the equation as C is function of  time and (t) will vary as 1,2,3 for respective hours.

To find the value of b we have to understand that it is dependent on percent increase if there is increment of 15\% then b=1+15\%=1+\frac{15}{100}=1+0.15=1.15

So the exponential function will be C(t)=y(b)^t ,plugging the values it will be equivalent to C(t)=1800(1+0.15)^1

Check:

15\% of 1800 =0.15\times 1800=270

So in first hour the cells will increased by a quantity of 270 cells.

The number of cells after an hour in the petri dish =(1800+270)=2070

That can also be from the formula.

C(t)=1800(1.15)^1=2070

So the exponential function is C(t)=y(b)^t\ Or\ C(t)=1800(1.15)^1

y will increase exponentially as the value of t increase.

Greg feeds his dog 2/3 pounds of dog food for each meal. Greg has just bought 18 pounds of dog food. For how many meals will the
yan [13]
We can divide 18 pounds by 2/3 pounds to find how many servings of meals the dogs will have.
We will use the keep change flip rule to solve this.
18 / 2/3 is then the same as 18 x 3/2
We then multiply across to get
54/2
This would be 27 meals that the food will last
