Answer:

144

Step-by-step explanation:

Jane has 2 times as many books as Jill, so there are 3 parts. Two parts Jane and one part Jill. So, divide 216 by 3 and it's 72, which equals one part. Jane has two parts, so 72 x 2. Jane has 144 books.

How can you tell if the slope of a tangent line belongs to a certain interval?
Mila [183]

The slope of the function is given by its derivative. You want to find the values of x such that the derivative is between -1 and 1.

... f'(x) = 0.4x +5

... -1 < 0.4x +5 < 1 . . . . . your requirement for slope

... -6 < 0.4x < -4 . . . . . . subtract 5

... -15 < x < -10 . . . . . . . multiply by 2.5


Any value of x that is between -15 and -10 will be one where the tangent line has a slope between -1 and 1.


_____

The graph shows tangent lines with slopes of -1 and +1. You can see that the slope of the graph of f(x) is between those values when x is between the tangent points.

Reika [66]

Answer:

-201.1

-200.9

-200

201

201.8

Step-by-step explanation:

For the given statement we have come to know that number in the line who have negative vales are less than the positive value

so in the number line we can see that

-201.1 is negative value in the number line and it has least value so

next value is -200.9 who is also negative and least but greater than -201.1

moving towards next we can see the value of 200 who is also negative but greater than from -200.9 so moving towards next

we can see that 201.8 is positive value so it is greater from all the past values

next the value 201 is greater than 200

so after these explanation you can see that numbers moving from negative to positive values and its show greatest values as well

hope it will be brainliest to you .

thank you
