The standard equation for the circle centre can be written by using this formula: (x-h)² + (y -k)² = r²
So, the equation in this case is: (x+6)² + (y-7)² = 81
Altitude is a perpendicular
from
a vertex ( the point where the two rays meet to form an angle)
to
a line containing the base ( could be the base or an extension of it)
X=2y because whenever x goes up one, y goes up two
Answer:
(3,3)
Step-by-step explanation:
Use the midpoint formula to find your answer. The formula is
.
If that equation looks funny then let me explain. You need to add 10 and -4 together, then divide it by 2. You also need to add -3 and -9, then divide that by 2.
Answer:
7pi/5
Step-by-step explanation:
A coterminal angle is the original angle ± 2pi radians
So to find a coterminal between 0 and 2pi you will need to substract 2pi's until you get one within that interval
17pi/5 - 2pi = 17pi/5 - 10pi/5 = 7pi/5
and this is already the answer ^
