In domain and range of a relation, if R be a relation from set A to set B, then
• The set of all first components of the ordered pairs belonging to R is called the domain of R.
Thus, Dom(R) = {a ∈ A: (a, b) ∈ R for some b ∈ B}.
• The set of all second components of the ordered pairs belonging to R is called the range of R.
Thus, range of R = {b ∈ B: (a, b) ∈R for some a ∈ A}.
Therefore, Domain (R) = {a : (a, b) ∈ R} and Range (R) = {b : (a, b) ∈ R}
Answer:
y= 11 | 19 | 27 |35 | 43 |
Answer:
Step-by-step explanation:
area = 1/2ab sin (angle)
area = 1/2(9.5)*(23)*sin(85)
area = 19.24 yards
Answer:
A: radius of the sphere
Step-by-step explanation:
The formula for surface area is A = 4πr^2
With r being the radius and A the surface area.
For volume it is
V= (4/3)πr^3
Step-by-step explanation:
8÷2(2+2) = <u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>8</u><u>. </u><u> </u><u> </u><u> </u><u> </u>
2(2 + 2)
= <u> </u><u> </u><u> </u><u> </u><u> </u><u>8</u><u>. </u><u> </u><u> </u><u> </u>
4 + 4
