2000 times 0.60 = 1200 doctors

6 0

3/5=0.6

x= 2000* 3/5

x=2000*0.6

x=1200

so... <u>1200 doctors use brand X aspirin.</u>

Which shows 9.635 written in expanded form, using powers of ten
Aleonysh [2.5K]

Step-by-step explanation:

The expanded form of 9.635 is given by :

9.635 =9+\dfrac{6}{10}+\dfrac{3}{100}+\dfrac{5}{1000}

or

9.635 =9+0.6+0.03+0.005

We can write it using the powers of ten.

9.635 =9.635 \times 10^0

10⁰ is equal to 1.

Hence, this is the required solution.

Tom is the deli manager at a grocery store.He needs to schedule employees to staff the deli department at least 260 person-hours
Drupady [299]
I hope this is right but:
Let n=number of full time employees

260<=20+n*40
260-20<=N*40
240<=n*40
n>=240/40
n>=6 full time employees

which means he would have to hire at least 6 or more fully time employees

Though I'm not sure if the attached file is the graph you are looking for

Plz help, I'm taking an Advanced class (Algebra) Will give brainliest ✔✔✔✔✔✔✔✔✔
bija089 [108]

Part A:

The average rate of change refers to a function's slope. Thus, we are going to need to use the slope formula, which is:

m = \dfrac{y_2 - y_1}{x_2 - x_1}

  • (x_1, y_1) and (x_2, y_2) are points on the function

You can see that we are given the x-values for our interval, but we are not given the y-values, which means that we will need to find them ourselves. Remember that the y-values of functions refers to the outputs of the function, so to find the y-values simply use your given x-value in the function and observe the result:

h(0) = 3(5)^0 = 3 \cdot 1 = 3

h(1) = 3(5)^1 = 3 \cdot 5 = 15

h(2) = 3(5)^2 = 3 \cdot 25 = 75

h(3) = 3(5)^3 = 3 \cdot 125 = 375


Now, let's find the slopes for each of the sections of the function:

<u>Section A</u>

m = \dfrac{15 - 3}{1 - 0} = \boxed{12}

<u>Section B</u>

m = \dfrac{375 - 75}{3 - 2} = \boxed{300}


Part B:

In this case, we can find how many times greater the rate of change in Section B is by dividing the slopes together.

\dfrac{m_B}{m_A} = \dfrac{300}{12} = 25


It is 25 times greater. This is because 3(5)^x is an exponential growth function, which grows faster and faster as the x-values get higher and higher. This is unlike a linear function which grows or declines at a constant rate.
