Answer:
( 3, 5.5 )
Step-by-step explanation:
Let,
( x1, y1 ) = ( 7, 3 )
Where,
x1 = 7
y1 = 3
Let,
( x2, y2 ) = ( - 1, 8 )
Where,
x2 = - 1
y2 = 8
Formula : -
Midpoint = ( x1 + x2 ) / 2, ( y1 + y2 ) / 2
Midpoint of AB
= ( - 1 + 7 ) / 2, ( 8 + 3 ) / 2
= 6 / 2, 11 / 2
= ( 3, 11 / 2 )
= ( 3, 5.5 )
P(0,0) and Q(2a , 0)
Midpoint PQ
x = (x1 + x2)/2 and y = (y1 = y2)/2
Midpoint:
x = (2a +0)/2
= 2a / 2
= a
y = (0+ 0)/2
= 0/ 2
= 0
So midpoint PQ (a , 0)
Answer is the 1st option
(a, 0)
Answer:
angle 1 is 35° angle 2 is 90° angle 3 is 55°
Answer:
f(x) = (x - 10) (x + 10)
Step-by-step explanation:
The equation looks like the difference of squares so 5 and 20 are out
-10 x -10 = 100
-10 x 10 = - 100
so (x - 10) (x + 10)
