Compute 41, 42, 43, 44, 45, 46, 47, and 48. Make a conjecture about the units digit of 4n where n is a positive integer. Use str
padilas [110]

Answer:

The conjecture is that the unit digit of 4^n = 4 when n = odd also 4^n = 6 when n = even

Step-by-step explanation:

4^1 = 4\\4^2 = 16\\4^3 = 64\\4^4 = 256 \\4^5 = 1024\\4^6 = 4096\\4^7 = 16384\\4^8 = 65536

The conjecture is that the unit digit of 4^n = 4 when n = odd also 4^n = 6 when n = even

To prove this conjecture

4^1 = 4\\4^2 = 16 unit digit = 6

hence the property is true for ; n = 1 and n = 2 and also for every odd and even number ( i.e. from 1  to 8 )

You download 12 news songs to your phone. Then you delete 5 old songs.Write each amount as an integer.
Gennadij [26K]
Hey there! :D

When you have a value, it is usually positive.

For example, if I have 5 chocolate bars, then I have +5 chocolate bars. 

When you take away a value, it is usually negative.

For example, I have 3 chocolate bars away, then I would have 3 fewer chocolate bars. (-3) 

Integers are negative or positive whole numbers.

12 songs= 12 <== the integer

Delete 5 old songs= -5 <=== the integer

I hope this helps!

Step-by-step explanation:

h=V

πr2=41.5

π·22≈3.30247

V=πr2h=π·42·7≈351.85838

V=πr2h=π·42·3≈150.79645

Two thirds a number plus 4 is 7
Sergio039 [100]
(2/3)x+4= 7

Subtract 4 from both sides
(2/3)x= 3

Divide both sides by 2/3. To divide by a fraction, multiply the first number by the reciprocal of the second.
3*3/2= 9/2

Final answer: 9/2 or 4.5
