Show that 21^n, n €N can never ends with 0,2,4,6 and 8​
erastovalidia [21]

Answer:

Step-by-step explanation:

21 ^n = (3 \times 7)^n

21 has no 2 in it's prime factorization. So it can never end in 0, 2 , 4 , 6 , 8.

 OR

Odd number raise to any number is always odd, Which does not include 2, 4, 6 , 8.

So 21^n does not end with 0, 2, 4 , 6 , 8.

I need help with this please

To find slope, pick any 2 points and use formula: (y2-y1)/(x2-x1)
2 points on line: (4,0), (0,-2)
(-2-0)/(0-4) = -2/-4 = 1/2
a) the slope is 1/2

Y = 1/2x + b
0 = 1/2(4) + b
0 = 2 + b, b = -2
b) -2 is the y intercept

Put the equation together
c) y = 1/2x - 2

David and Patti each decomposed 138. David wrote 1 + 1/8 + 3/8. Patti wrote 4/8+2/8+5/8.
BaLLatris [955]

Answer:

Both are wrong.

Step-by-step explanation:

We have that:

Both decomposed the fraction \frac{13}{8} into a sum of fractions. Whoever's decomposition sum has a value of \frac{13}{8} is correct.

David:

1 + \frac{1}{8} + \frac{3}{8} = \frac{8}{8} + \frac{1}{8} + \frac{3}{8} = \frac{8+1+3}{8} = \frac{12}{8}

\frac{12}{8} \neq \frac{13}{8}, which means that David is wrong.

Patti

\frac{4}{8} + \frac{2}{8} + \frac{5}{8} = \frac{4+2+5}{8} = \frac{11}{8}

\frac{11}{8} \neq \frac{13}{8}, which means that Patti is wrong.

So the answer is that both are wrong.
