Salt is a solid. S<span>olids are more dense than liquids: they have more atoms packed into the same space. The atoms are tightly packed together and stay in shape all by themselves, though they do move about on the spot.</span>

3. JK Rowling and R.L. Stine are both reading the Hunger Games. J.K. reads 35

Crank

Answer:

Part A:

For J.K. Rowling: 17.5pages/hour

For R.L. Stine: 15pages/hour

Part B:

J.K. Rowling will finish the book first.

Step-by-step explanation:

Part A:

The rate of change in this case represents how much changes a variable in a specific period of time. The variable is the amount of pages.

You have to calculate the amount of pages that J.K. Rowling and R.L. Stine read in one hour.

For J.K. Rowling, 35 pages every 2 hours can be written as:

If you divide 35/2 you can obtain the amount of pages in one hour:

17.5pages/hour (17.5 pages per hour)

For R.L. Stine, 45 pages every 3 hours can be written as:

If you divide 45/3 you can obtain the amount of pages in one hour:

15pages/hour (15 pages per hour)

Part B:

In order to calculate who will finish the hunger games first, you have to calculate the amount of time needed to finish the book.

For J.K. Rowling:

You have to multiply 355 pages by (because in one hour she reads 17.5 pages) to obtain the amount of hours

For R.L. Stine:

You have to multiply 355 pages by (because in one hour he reads 15 pages) to obtain the amount of hours

So, J.K. Rowling will finish the book first because she needs less time than R.L. Stine.

Which graph represents the function?

Setler79 [48]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

1) $f(x)=(x+2)^2$ -----> For the interval (-∞,-1)

Note The value of x=-1 is a open circle ( is not included)

This is a vertical parabola open upward

The vertex is a minimum

The vertex is the point (-2,0)

2) $f\left(x\right)=\left|x\right|+1$ ----> For the interval [-1,1]

Note The value of x=-1 and x=1 are closed circle ( both values are included)

This is an absolute function open upward

The vertex is the point (0,1)

3) $f(x)=-\sqrt{x}$ -----> For the interval (1,∞)

Note The value of x=1 is a open circle ( is not included)

The value of f(x) is negative for all values of x

therefore

The graph in the attached figure
