Answer:
The correct option is a.
Step-by-step explanation:
Given information:
Number of elements in set A = 4
Number of elements in set B = 3
We need to find n(A × B). It means we have to find the number of elements in set A × B.
If P and Q are two sets with elements m and n respectively, then the number of element in the set P × Q is m × n.



The value of n(A × B) is 12. Therefore the correct option is a.
Answer:
The right choice is Esther's
Step-by-step explanation:
Present worth of GH¢ after 3 years is better as its present really worth may be very high than GH¢ a thousand of today. Here fee of interest is not given to compare however GH¢ 3000 after three years will be equivalent to present well worth GH¢ 1000 if charge of interest >44.5% which may be very very excessive. Thus charge of interest > 44.5% Then GH¢ 3000 payable after 3 years could be equivalent to GH¢ 1000 Hence vide has made the proper preference. If interest price >44.5%.
Then Esther's preference will he right. (thinking about time value of money).
The triangle formed from the height of the cone and the radius of its base is a special 3,4,5 triangle. The slant height is 5cm.
Recall that the area of a circle = pi*r^2
Substitute 3 in for r
Area = pi * (3)^2 = 9pi
SA = pi*r*l + B
Substitute our values into the equation
SA = pi * 3 * 5 + 9pi
SA = 15pi + 9pi
SA = 24pi cm^2
