Answer:
Step-by-step explanation:
Given:
To find:
Simplified result of the radical
Solution:
If a value is in square root and it is not a perfect square then we can solve it by finding the answer by factoring down it to smaller factors which are perfect squares and finding the square root of the smaller values
Now
68 can be written as
68 = 2 * 2 * 17
The given is
It can be written as
=
Now
= .
so given become
∵√2² = 2
∵a*√b=a√b
Answer:
m MN = 70°
Step-by-step explanation:
∠MLN is an angle formed by the chords ML and LN and is calculated as
∠MLN = 0.5( m arc MN ), that is
35° = 0.5 arc MN ( multiply both sides by 2 )
arc MN = 2 × 35° = 70°
Answer:
or 50%
Step-by-step explanation:
Cube has 6 sides = 3 odds and 3 even
probability is found using
which is
1/2 = 50%
Answer:
See explanation below
Step-by-step explanation:
<em>R(x,y) means x and y are related</em> according to previous established relation.
For example R(x,y) could be “x<y” if x, y are integer numbers, or R(x,y) could be “x and y are friends” if x and y are people.
<em>The set which x and y belongs to, need not be the same.</em>
<em>∀x∀y R(x, y) means: for every x in a set S and every y in a set T, x and y are related.
</em>
The logical conector “and” is commutative, that is to say, the sentence “for every x in a set S and every y in a set T x and y are related” is the same as “for every y in a set T and every x in a set S x and y are related”.
This last sentence is ∀y∀x R(x, y).
So, they are the same thing.
