The rule (x,y)→(−x,y) maps △ABC to △A′B′C′.Which statement correctly describes the relationship between △ABC and △A′B′C′ ? The triangles are congruent because △A′B′C′ is a rotation of △ABC, and a rotation is a rigid motion. The triangles are congruent because △A′B′C′ is a reflection of △ABC, and a reflection is a rigid motion. The triangles are not congruent because △A′B′C′ is a translation of △ABC, and a translation is not a rigid motion. The triangles are not congruent because △A′B′C′ is a reflection of △ABC, and a reflection is not a rigid motion.

A bird is flying 100 feet off the ground. Looking down at a 45° angle, it sees a mouse standing still. Approximately how far will the bird have to fly to catch the mouse?

Answers

The situation is describe on picture. 
We can use relations in two 45-degree angles triangle.
In this example a=100 feet and the distance which bird have to fly to catch the bird is a* \sqrt{2} [/tex] so substituting our data we have:  100* \sqrt{2} [/tex]
So  the distance is about 141,4213562 feet.

What is the answers to this math 3-3x6+2=

What is the difference in simplest form? (n^2+10n+21/n^2+3n-28)-(3n/n-4)

Answers

Answer:

(3-2n)/(n-4)

Step-by-step explanation:

We have been given the expression

(n^2+10n+21)/(n^2+3n-28)-(3n)/(n-4)

Let us write the numerator and denominator of first expression in factored form using AC method.

n^2+10n+21\n=n^2+7n+3n+21\nn(n+7)+3(n+7)\n(n+7)(n+3)

And the factors of denominator is

n^2+3n-28\n=n^2+7n-4n-28\nn(n+7)-4(n+7)\n(n+7)(n-4)

Therefore, the expression becomes

((n+7)(n+3))/((n+7)(n-4))-(3n)/(n-4)\n\n\text{Cancel the common terms}\n\n(n+3)/(n-4)-(3n)/(n-4)\n\n\text{Denominator of both rational expression is same}\n\text{hence, we can directly add the numerators}\n\n(n+3-3n)/(n-4)\n\n(3-2n)/(n-4)

Thus, the simplified form is (3-2n)/(n-4)

The answer is (-2n+3)/(n-4)
