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
.
Answer:
153.94
Step-by-step explanation:
c=2r*r
The radius is half of the diameter.
To find the radius you will divide 49 inches by 2.
You should get a total of 24.5
Now that you have your radius you are going to use the circumference formula to solve.
C= 2r*r
C=2(24.5)*(24.5)
type that into the calculator (without the parenthesis) and boom your done!
You answer should be 153.938
then you round to get a total of 153.94
I hope i was able to help!
It should be 34.3 because I think you have to add up all the numbers
Y=4(0-2)^2-1
y=15
(0,15)
plug 0 for x
0=4(x-2)^2-1
(5/2,0) and (3/2,0)
plug 0 for y
