Answer:
Step-by-step explanation:
Given
Plane travels 240 miles East of North
Position vector
Then the plane travels 180 miles East of North
Total distance traveled in North direction is given by coefficient of \hat{j}
i.e. North
Total distance traveled in East direction is given by coefficient of \hat{i}
East

Answer:
it is 6/7, you can simplify that fraction by dividing with 7
To write this expression as a positive exponent we use this rule of exponents: xa=1x−a. 5−3=15−−3=153. Use this rule for exponents: xa=1x−a. 5−3=15−−3=153=1125.

Step-by-step explanation:
The way you get the area of a parellelogram is the same as the way of a rectangle or square.
Answer:
let cp be x
sp= 115x/100 ---(when 15%gain)
sp = 88x/100------(when 12% loss
according to question
115x/100 - 88x/100 = 81
or, (115x-88x)= 8100
or, 27x = 8100
or, x= 8100/27
x = 300
hence cp is RS 300
X + 19 >= 8.2
x >= 8.2 -19
>= -10.8
