Prove that: 5^31–5^29 is divisible by 100.

ANEK [815]

Answer:

See explanation

Step-by-step explanation:

Consider the expression

$5^{31}-5^{29}$

First, factor it:

$5^{31}-5^{29}=5^{29}\cdot(5^2-1)=5^{29}\cdot (25-1)=24\cdot 5^{29}$

Note that

$100=25\cdot 4$

Then

$5^{31}-5^{29}=24\cdot 5^{29}=6\cdot 4\cdot 25\cdot 5^{27}=6\cdot 100\cdot 5^{27}$

This shows that number 100 is a factor of the expression $5^{31}-5^{29}$ and, therefore, this expression is divisible by 100.

The distance y (in centimeters) a spring is compressed by a force x (in kilograms) is given by

kirza4 [7]

Answer:

(x, y) = {(20, 1.3), (40, 2.6), (60, 3.9), (80, 5.2), (100, 6.5)}

Graph C represents the table of values

Step-by-step explanation:

To complete the table, substitute each value of x into the equation, $y = 0.065x$ , to find each corresponding y-value.

Thus:

✔️When x = 20:

$y = 0.065x$

$y = 0.065(20)$

$y = 1.3$

✔️When x = 40:

$y = 0.065x$

$y = 0.065(40)$

$y = 2.6$

✔️When x = 60:

$y = 0.065x$

$y = 0.065(60)$

$y = 3.9$

✔️When x = 80:

$y = 0.065x$

$y = 0.065(80)$

$y = 5.2$

✔️When x = 100:

$y = 0.065x$

$y = 0.065(100)$

$y = 6.5$

✔️<em>The graph of that represents this table of values is graph C. See attachment.</em>
