Answer:

Step-by-step explanation:

Givens

The old record is 6.75 meters.
The new record is 8.5 meters.

If 6.75 meters represents 100%, which percentage would represents 8.5 meters? (we use the rule of three).

$8.5 \times \frac{100 \%}{6.75 } =125.93 \%$

Then, we subtract 125.96% - 100% = 25.96%

Therefore, the percentage between the two records is 25.96%

Find the first term of the following geometric sequence ----,42,126,378,1,134

sergey [27]

Since it is a geometric sequence each term will be a specific multiple of the term preceding it, called the common ratio...

126/42=378/126=1134/378=3

The sequence is a(n)=a(3)^(n-1) and we know the second term is 42 so:

42=a(3)^(2-1)

42=3a

a=14

So the first term is 14.

For any integer x,x2-x will always produce an even value

Levart [38]

Consider expression $x^2-x.$ First, you can factor it:

$x^2-x=x(x-1).$

Since x is integer number, then you can see that x-1 is previous integer number (x-1 is 1 unit smaller than x).

Therefore, x-1 and x are two consecutive integers. When you have two consecutive integers, one of them is always even and one is always odd. Multiplying even integer number by odd integer number you always get even integer number.

Thus, $x^2-x$ is always even.
