Hey guys pls help ASAP i need it for my test also pl explain your anwer

The longer leg of a 30° 60° 90° triangle is 16 times square root of three how long is a shorter leg

In which form is the following function written? y = - 2(x – 3)(x + 5)

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
