Answer:
Step-by-step explanation:
An ellipse is defined as the locus of all points,the sum of whose from two given points is constant. Here z is a complex number whose distance from (1,0) and (−1,0) is constant. Hence the locus of z is an ellipse in the complex plane. Hence z will be all those points which lies on the ellipse with focus (−1,0) and (1,0).
Answer:
3/4
Step-by-step explanation:
For lines to be parallel, only their y-intercepts have to be different.
Height of entire house = height of first floor + height of second floor + height of attic
Rearrange to make "Height of attic" the subject
To do this, place "height of first floor" and "height of second floor on the other side of the equation"
So:
Height of attic = Height of entire house - height of first floor - height of second floor
Height of attic = 241/3 - 85/6 - 81/2
Next problem, they are all in fractions.
So make a common/same denominator (bottom number)
Let's make the common denominator 6.
241/3 x 2/2 = 482/6
*It still has the same value
85/6 already has a denominator of 6 so no need to do anything to it.
81/2 x 3/3 = 243/6
Height of attic = 482/6 -85/6 -243/6
Simplify it to one fraction since they all have the same denominator now:
Height of attic = (482 - 85 - 243) / 6
Height of attic = 154/6
Compatible Numbers are numbers that are easy to divide mentally
Answer:
The 20 mph headwind slows the plane down. This is because the headwind comes at the head of the plane and goes in the opposite direction of the plane.
So the plane's actual speed (with the wind included) is 550-20 = 530 mph.
