Answer:
Step-by-step explanation:
The finite set is in which we can count the elements which has finite number of elements
option 1 is not correct because we can not count the whole numbers they could extended upto infinite.
Option 2 is correct that is finite because condition is given that is natural numbers less than 100,000.
Option 3 is finite because we can count all letters of the alphabet.
Option 4 is not finite because all odd numbers can be extended upto infinity.
Option 5 is correct that is finite because world's population will be a finite number.
Option 6 is finite because it is empty set which is finite.
Answer:
3
Step-by-step explanation:
The notation "f(4)" means you put 4 where x is in the algebraic expression, then do the arithmetic.
f(4) = 2·4 -5
= 8 -5
= 3
Answer:
70/3 πcm
Step-by-step explanation:
hope this helps
X=2 because 3 times 2 is 6 and then you add 6 and 7 together and get 13.
Answer:
Options (1), (3), (5) and (6)
Step-by-step explanation:
Option (1)
Both the circles M and H are same in shape. Therefore, both are similar.
True
Option (2)
MH = MS = [Radii of a circle]
MH = MO + OH
MH = ME + OH [Since, MO = ME]
MH = 10 + 25 = 35 cm
Area of circle M = πr²
= π(35)²
= 1225π
Area of circle H = π(25)²
= 625π

Area of M = 1.96(Area of H)
False
Option 3
OH + MS = 25 + 35
= 60 cm
True
Option 4
m∠HMS = 90°
Can't be figured out with the given informations
False
Option 5
Diameter of circle H = 2(radius)
= 2(25)
= 50 cm
True
Option 6
Circumference of circle S = 2πr
= 2π(ES)
Circumference of circle M = 2π(MS)
Ratio of the circumference of circle S and M = 
= 
True.
Options (1), (3), (5) and (6) are correct.
