Answer:
The number is 38,478
Step-by-step explanation:
* Lets explain how to find the number
- The number is 5-digit
* Ones ⇒ the last digit
* Tens
* Hundreds
* Thousands
* Ten thousand
- The ones digit is the same as the last digit of last year's calendar year
∵ The last year is 2018
∴ The last digit is 8
∴ The ones digit is 8
- The ones digit is the same as the thousands digit
∵ The ones digit is 8
∴ The thousands digit is 8
- The ten thousands digit is five less than the thousands digit
∵ The thousands digit is 8
∴ The ten thousands digit is 5 less than 8
∵ 8 - 5 = 3
∴ The ten thousands digit is 3
- The last two digits sum to 15
∵ The last two digits are ones and tens digits
∵ The ones digit is 8
∵ 15 - 8 = 7
∴ The tens digit is 7
- There is one 4 in the number
∵ The hundreds digit is empty
∴ The hundreds digit is 4
* <em>The number is 38,478</em>
By Stokes' theorem,

where

is the circular boundary of the hemisphere

in the

-

plane. We can parameterize the boundary via the "standard" choice of polar coordinates, setting

where

. Then the line integral is


We can check this result by evaluating the equivalent surface integral. We have

and we can parameterize

by

so that

where

and

. Then,

as expected.
C=pid
d=diameter
d=4
C=4pi
tada
if you want
aprox pi=3.14
C=12.56 units
Answer:
Slope: 1/5
Step-by-step explanation:
To find the slope of a line when given two points, you find the change in y over the change in x.
1 - (-1) = 2 (change in y)
4 - (-6) = 10 (change in x)
2/10 simplified is 1/5.
Hope this helps :)
