Ellipses, parabolas, and infinity. A parabola can be defined as the locus of points equidistant from a fixed point (called the focus) and a fixed line (called the directrix). But we know from projective geometry that parabolas and ellipses are essentially the same object.
The answer is 1*10^-1 (the -1 would be in superscript).
Answer:
-16 + 4 = -12
Step-by-step explanation:
Answer:
rectangle A:
LENGTH:9
WİDTH:6
rectangle B:
LENGTH:9
WİDTH:3
Step-by-step explanation:
if you want to find the length of a square you should know that in a square all 4 sides lengths are the same so the are is give as 36 to find 1 side of the length we have to divide 36 with 4(because there are 4 sides)
which means the lengths of each side is 9.
it is the same as in rectangle a and b length hasn't changed only the width has changed.
we can also find the width with the information given us about its ratio.
it says that The ratio of area A to area B is 2:1
the length is 9:
we can make it simple like this lets say 2x and 1x has to give us 9
so we can say 3x=9,x=3
to find the width we can say that 2x width is for rectangle A and 1 x is rectangle B. so x was 3:
2x=6
1x=3
these are the widths of rectangle A and B
Number 3,is 2 number four, is 80,400
