Solve the following quadratic equation.

Nonamiya [84]

Given:

Consider the given equation is

$(x-18)^2=1$

To find:

The values of x.

Solution:

We have,

$(x-18)^2=1$

Taking square root on both sides, we get

$x-18=\pm\sqrt{1}$

$x-18=\pm 1$

Adding 18 on both sides, we get

$x-18+18=\pm 1+18$

$x=\pm 1+18$

Now,

$x=1+18$ and $x=-1+18$

$x=19$ and $x=17$

Therefore, the correct option is A.

Prove this conjecture

steposvetlana [31]

Answer:

See explanation

Step-by-step explanation:

Consider the natural number $n(n+1)(n+2).$

If $n$ is the natural number, then $n+1, \ n+2$ are next two natural numbers, so numbers $n,\ n+1$ and $n+2$ are three consecutive numbers.

Given three consecutive natural numbers, one of them is always even number and one of them is always multiple of 3, so the product

$n(n+1)(n+2)$

is divisible by 6.

Which phrase best describes the correlation between the variables?

Mandarinka [93]

The best answer would be B, moderate negative.
Visually, you can tell looking at the scatter plot and going from left to right, the value of y generally gradually decreases. The reason it isn't a strong negative is because there are still some values that stray away from this pattern.
