Let this number be represented by the variable "n"
product of 4 and n is multiplying4 and n
4 * n = 5.6
divide 4 to both sides to isolate the variable on one side
n=1.4
12.5 x 2 (you need the diameter to find pi) =25pi ft
Answer:
Vertex is (3, 256)
Step-by-step explanation:
The vertex means that at 3 seconds, the highest point the ball will reach is 256 units in the air.
The cross product of two vectors gives a third vector

that is orthogonal to the first two.

Normalize this vector by dividing it by its norm:

To get another vector orthogonal to the first two, you can just change the sign and use

.
