Answer:
Commutative
Step-by-step explanation:
2 + 4 = 4 + 2 as an example
Given:
Two endpoints of a diameter of a circle:
P (-7, -10)
Q (3, 2)
a) To find the center of the circle, find the midpoint of the two points:
midpoint:
(x2 - x1 )/ 2 , (y2 - y1) / 2
x= (2 - (-7))/2 = 4.5
y= (3 - (-10))/2 = 6.5
Therefore, the center of the circle is at C(4.5, 6.5)
b) To find the radius of the circle, we need to find the distance between the two points and divide by 2.
d = √(y2-y1)^2 + (x2 - x1)^2
d = √(2-(-7))^2 + (3 - (-10))^2
d = 5√10 = diameter
r = d/2 = 5√10 /2
Answer:
4y
Step-by-step explanation:
4y is a term in itself 3 and x separate aren't and 4x + 7 is an equation not a term.
Answer:
Q, R
Step-by-step explanation:
All of the listed sets of numbers are Real numbers. The fraction is not an integer, so is not in sets I or N. Because it is a fraction, it is in set Q, and because R includes Q, ...
the number is in sets Q and R
On #29 x = 12 and <apb = 90° and <dcb = 40° and on #30 all I dont even understand, sorry
