Answer:
The answer is "
"
Step-by-step explanation:
Distance
midpoint height 
let
Gradient 
Perpendicular Gradient
midpoints 
Similar to perpendicular
Now I'll obtain the perpendicular bisector solution
An equation of the center circle
radius will be.
Alexandera=a
imani=i
a is 8 more than i or
a=8+i
the sum of the 2 numbers is 50 or
a+i=50
a=8+i
so subsitute 8+i for a in a+i=50
8+i+i=50
8+2i=50
subtract 8 from both sides
2i=42
divide both sides by 2
i=21
subsiutte into a=8+i
a=8+21
a=29
a=29
i=21
The easiest way is to try the point (-4,1), that is, x=-4, y=1,
to see which equation works.
b works.
The usual way to do it is to find the equation of the circle
standard form of a circle is (x-h)²+(y-k)²=r², (h,k) are the coordinates of the center, r is the radius.
in this case, the center is (-2,1), so (x+2)²+(y-1)²=r²
the given point (-4,1) is for you to find r: (-4+2)²+(1-1)²=r², r=2
so the equation is (x+2)²+(y-1)²=2²
expand it: x²+4x+4+y²-2y+1=4
x²+y²+4x-2y+1=0, which is answer b.
Answer:
The bottom right histogram is the correct one.
Step-by-step explanation:
Carrots weight 40-49 kg = 2
... of weight 50-59 = 6
... of weight 60-69 = 4
.. of weight 70-79 = 1
