Answer:
The answer is B
Step-by-step explanation:
Quadratic equations always have two answers unless the radical is a negative. You can not square root negatives.
I am almost positive that the answer is A.
Answer:
centroid divides median into the ratio 2:1 then
PC/CY=9/x=2/1
x=4.5
then the total length PY = 9+4.5=13.5
Answer:
Infinitely
Step-by-step explanation:
Solutions to a system are the intersection points. Since these two lines are the same line they intersect everywhere. There are infinitely many solutions.
Answer:
48°
Step-by-step explanation:
Given the trigonometry equation
sin(52)= cos(5x-2)...1
According to the quadrant:
Sin(θ) = cos(90-θ)
Sin52 = cos(90-52)
Sin52 = cos48... 2
Substituting 2 into 1:
Cos48 = cos(5x-2)
48 = 5x-2
5x = 48+2
5x = 50
x = 10°
The smallest of the angle will be angle 5x-2 = 5(10)-2
= 50-2
= 48°
