Answer:
(3,-7)
Step-by-step explanation:
Midpoint Formula
(3,-9) = ((3+x)/2 , (-11+x)/2)
Solve for x coordinate

Solve for y coordinate

Therefore point s is (3, -7)
Answer:
a
Step-by-step explanation:
4*1/7
Answer:
A graph shows zeros to be ±3. Factoring those out leaves the quadratic
(x-2)² +1
which has complex roots 2±i.
The function has roots -3, 3, 2-i, 2+i.
Step-by-step explanation:
Answer:
3/10
Step-by-step explanation:
The central angle of the arc is
.
The circumference of an arc of a circle is given as:

where C= circumference of the circle
θ = central angle of the arc
Therefore, the circumference of the arc is:

The circumference of the arc will be 3/10 of the circumference of the circle.
The correct answer is 3/10
