Find the set below using A=(5,6,9), and so on (Explanation is in picture)

anzhelika [568]

The result is: {5,6,9}

Step-by-step explanation:

Given

U = {0,1,2,......,10}

A = {5,6,9}

B = {0, 6, 7, 10}

We have to find

(A∩B)U(A∩B')

First of all,

B':

B' = U -B = {0,1,2,......,10} - {0, 6, 7, 10}

= {1,2,3,4,5,8,9}

A∩B':

A∩B' = {5,6,9} ∩ {1,2,3,4,5,8,9}

= {5,9}

A∩B:

A∩B = {5,6,9} ∩ {0, 6, 7, 10}

={6}

At the end we have to find union

(A∩B)U(A∩B') = {6} U {5,9}

(A∩B)U(A∩B') = {5,6,9}

Hence,

The result is: {5,6,9}

A triangle has sides with lengths of 60 feet, 63 feet, and 87 feet. Is it a right triangle?

Sedaia [141]

Answer:

Yes

Step-by-step explanation:

We can use the Pythagorean Theorem to check if this triangle is a right triangle:

$a^2+b^2=c^2$

Note that $a$ and $b$ are the legs of the triangle and $c$ is the hypotenuse:

Substitute the lengths of the sides into the equation:

$60^2+63^2=87^2$

$3600+3969=7569\\7569=7569$

Therefore this triangle is a right triangle.
