Step-by-step explanation:

The digital root of a number is the single digit that you get by adding all of the digits of the original number together. If the result of that is multiple digits, you add those digits together, repeating the process until you get a single digit. That digit is the digital root of the original number.

example given

257520643

2+5+7+5+2+0+6+4+3

7+12+2+10+3

7+1+2+2+13

8+4+1+3

8+4+4

Find the perimiter of this shape
juin [17]

Answer:

The perimeter of the shape is (7x²+10x+81) inches.

Step-by-step explanation:

When finding the perimeter of a shape, you have to add up all the side lengths :

p = 31 + (4 {x}^{2}  + 8x) + (3 {x}^{2}  - 5x + 20) + (7x + 30)

p = 31 + 4 {x}^{2}  + 8x + 3 {x}^{2} - 5x + 20 + 7x + 30

p =( 7 {x}^{2}  + 10x + 81) \: inches

Find the volume of the solid of revolution formed by rotating about the x--axis the region bounded by the given curves.
hichkok12 [17]

Answer:

2\pi(e^2-e^{-4})

Step-by-step explanation:

We are given: f(x)=2e^x

So, the integral will be used to calculate the volume.

V = \pi\int\limits^1_{-2}(2e^x)^2dx=\pi\int\limits^1_{-2}4e^{2x}dx=2\pi e^{2x}|^1_{-2} =2\pi(e^2-e^{-4})
