Answer:
(x - 7)² + (y - 3)² = 5
Step-by-step explanation:
The center (h , k) is the midpoint of two end points of diameter
h = (9 + 5) / 2 = 7
k = (4 + 2) / 2 = 3
Equation of circle: (x - h)² + (y - k)² = r²
r = (√(9 - 5)² + (4 - 2)²) / 2 = √5
Equation: (x - 7)² + (y - 3)² = 5
Answer:
√21
Step-by-step explanation:
<u><em>Irrational number:-</em></u>
An irrational number is a type of real number which cannot be represented as a simple fraction . it cannot be expressed in the form of a ratio.
Example:-
√2,√3, ,......

Answer:
See Explanation
Step-by-step explanation:
The question is not clear. However, I will treat the question as:
and:
Solving: and
Divide both sides by 26
Divide both sides by 50
Solving and
Express 1 as 2^0
Remove bracket
Cancel out 2
Divide both sides by 6
Express 1 as 5^0
Cancel out 5^0
317 is the answer you are looking for.
Because the number is even, then the number of possible combinations will be: 110/2 = 55 let's consider a simpler example, the number: 10, then we have: 10+0, 9+1, 8+2, 7+3, 6+4, which is equal to 10/2 =5 combinations. Note: We are not considering permutations between the elements of the sum therefore 10+0, 0+10 counts as one combination.
