10 units to the right of -9 = 1
The coordinates are (10, 5).
Yes. Here is an example: Vector A: 10 units towards the right. Vector B: 9 units towards the left. This is the same as (-9) units to the right. A + B: 10 + (-9) = +1 units to the right. In fact, the resulting vector can be made arbitrarily small, if the two vectors are similar in size and point in opposite directions (or nearly so).
10(radical "2") units, or about 14.1 units.
It is: 9/10*9/10 = 81/100 or 0.81 square units
The 4 sided quadrilateral will form a right angled trapezoid when plotted on the Cartesian plane with parallel sides of 7 units and 9 units with a height of 6 units. Area of trapezoid: 0.5*(7+9)*6 = 48 square units.
The area of a rectangle is length times width.In this case, it is 10 x 9 = 90 square units.
It works out as 10 units Check: 0.5*9*10 = 45 square units
899 means 8 x 100s + 9 x 10s and 9 x units. So the 9 on the right hand side is the units.
Absolute 9
Total surface area of the cylinder: (2*pi*5^2) + (10*pi*9) = 140*pi square units
10 units
26 units.
