Step-by-step explanation:
18 + 4 = 22
then just add the negative to 22

A scale of 8cm:12cm would be a scale of 2/3. since this is the case, we can divide the scale drawing of the playground by the scale factor to get the length of the actual playground
12.4/0.6666 = 18.6
The answer is 18.6
The standard form of a parabola is
So, if you expand the square, you get
which is the standard form
The velocity or speed of the kayaker going north at a speed of 3 m/s and that of the current going east at a speed of 2 m/s create a resultant speed of √13 m/s. The new distance that has to be traveled by the kayaker in order to move 100 m north is calculated through the equation,
3 / √13 = 100 / x
The value of x is 120 m. The total time it will take for the kayaker to reach the destination is,
t = 120 / √13 = 33.33 s
If you cut length L from the 16 ft halyard, you are subtracting the value of L from 16. This means that the second piece should be 16-L feet long.
