Answer:

28%

Step-by-step explanation:

We get 30% off the original price

The new price is (100-30) = 70$ of the original price

Let x = the original price

The new price is .7x

Now get get an additional 60% off.  We pay (100-60) = 40 percent of the price

Take .7x * .4

The new price is .7*.4 x

                               .28x

This is 28 percent of the original price x

The diameter of a bacteria colony that doubles every hour is represented by the graph below. What is the diameter of the bacteri
SOVA2 [1]

For this case we have a function of the form:

y = A * (b) ^ x

Where,

A: initial population of bacteria

b: growth rate

x: number of hours

Since the diameter is double every hour, then:

b = 2

We must now look for the value of A.

To do this, we evaluate an ordered pair of the graph:

For (1, 2):

2 = A * (2) ^ 1

Clearing A we have:

2 = A * 2

A = \frac{2}{2}\\A = 1

Then, the function is given by:

y = 1 * (2) ^ x

For after 9 hours we have:

y = 1 * (2) ^ 9\\y = 512

Answer:

the diameter of the bacteria after 9 hours is:

y = 512
