It looks like you have to do distance formula. It's basically this:
D = (ignore the A, i dont know how to get rid of it sorry)
I would then plug in the points of A(1,7) and B(10,3).
D =
Then I would get the square root of 4^2 + 9^2
= square root of 16 + 81
= square root of 97
So the length of AB would be the square root of 97
Answer:
A = 8π cm²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here diameter = 8 , then r = 8 ÷ 2 = 4
The area of half a circle is then
A = π × 4² =
× π × 16 = 8π cm²
Answer:
Step-by-step explanation:
The union of two sets P and Q, denoted as is the set of all elements that are in the set P or in the set Q or in both sets P and Q.
Given:
P = {7, 8, 9, 10, 11}
Q = {1, 2, 3, 4, 5}
Then
When writing the union set, simply write all elements from both sets in on set.
