Find the distance between Point A(9, 10) and B(-1,9) to the nearest tenth.
olganol [36]

Answer:

10.0

Step-by-step explanation:

see attached for reference.

given two points in the x-y axis (x₁, y₁) and (x₂, y₂)

the distance bettween them is given by

Distance, D = √ (    (x₂-x₁)²   + (y₂-y₁)²   )

In our case we are given points (9,10) and (-1,9)

substituting these into the formula , we get:

D = √ (    (9-10)²   + (-1-9)²   )

= √ (    (-1)²   + (-10)²   )

= √ (    1   + 100   )

=√101

= 10.04988

= 10.0 (rounded to nearest tenth)

Factor 9x^2+66xy+121y^2
Korvikt [17]
Answer: (3x + 11y)^2

Demonstration:

The polynomial is a perfect square trinomial, because:

1) √ [9x^2] = 3x

2) √121y^2] = 11y

3) 66xy = 2 *(3x)(11y)

Then it is factored as a square binomial, being the factored expression:

 [ 3x + 11y]^2

Now you can verify working backwar, i.e expanding the parenthesis.

Remember that the expansion of a square binomial is:

- square of the first term => (3x)^2 = 9x^2
- double product of first term times second term =>2 (3x)(11y) = 66xy
- square of the second term => (11y)^2 = 121y^2

=> [3x + 11y]^2 = 9x^2 + 66xy + 121y^2, which is the original polynomial.
