The total change in altitude= 960ft.
Step-by-step explanation:
Rate at which balloon descend = 320 ft per minute
Time = 3 mins
Total height descended = 320 x 3
= 960 ft.
The total change in altitude= 960ft.
Answer:
12 bucks
Step-by-step explanation:
The perpendicular are B) ||u+v|| = sqrt ||u||^2 + ||v||^2 and D) ||u+v|| less than ||u||+||v||
We have given that,
The relationships hold true for the sum of the magnitudes of vectors u and v,
We have determined which are perpendicular.
The magnitude of a vector formula is used to calculate the length for a given vector (say v) and is denoted as |v|. So basically, this quantity is the length between the initial point and endpoint of the vector.
B) ||u+v|| = sqrt ||u||^2 + ||v||^2
AND
D) ||u+v|| less than ||u||+||v||
