Answer:

$4 \le x \le 6$

Step-by-step explanation:

The rate of change is the slope. The rate of change is the greatest for the slope with the greatest absolute value. In the graph, this is shown with the steepest inclination. That occurs from x = 4 to x = 6.

Answer:

$4 \le x \le 6$

Fred is 4 times as old as nathen and is also27 years older than nathen

docker41 [41]

Answer: Nathen is 9 years old and Fred is 36 years old.

Step-by-step explanation:

set Nathen's age = x

set Fred's age = 4x (because he is 4 times as old as Nathen)

4x = x + 27

3x = 27

x = 9 (Nathen's age)

4x = 36 (Fred's age)

Find the volume of the solid that lies between planes perpendicular to the x-axis at x = pi/4 and x = 5pi/4. The cross-sections

svp [43]

Answer:

The volume of the solid = π²

Step-by-step explanation:

As per the given data of the questions,

The diameter of each disk is

D = 2 sin(x) - 2 cos(x)

So its radius is

R = sin(x) - cos(x).

The area of each disk is

$= \pi \times(sinx-cosx)^{2}$

$= \pi \times [sin^{2}(x) - 2 sin(x) cos(x) + cos^{2}(x)]$

$= \pi[1-2sin(x)cos(x)]$

$= \pi[1-sin(2x)]$

Now,

Integrate from $x=\frac{\pi}{4}\ \ \ to\ \ \ x=\frac{5\pi}{4}$ , we get volume:

$V=\int_{\frac{\pi}{4}}^{\frac{5\pi}{4}} \pi[1-sin(2x)]dx$

After integrate without limit we get

$V=\pi[x+\frac{cos2x}{2}]$

Now after putting the limit, we get

V = π²

Hence, the required volume of the solid = π²

30. The table below shows the number of ants in an ant farm on different

Nitella [24]

Answer:

a)10

b)5120

Step-by-step explanation:

Given that number of ants double after every ten days, form a table that shows numbe of ants from day 1 to day 91

Day Number of Ants

1 10

11 20

21 40

31 80

41 160

51 320-----------------given

61 640------------------given

71 1280----------------given

81 2560

91 5120

Using the given values for number of ants and the number of days, you can notice the trend for values of days and number of ants.After every ten days, number of ants doubles.Using this information, you can navigate backwards up to day 1 and forward up to day 91
