Answer:
a)The component form is

b)The magnitude is √65
c) <2,14>
Step-by-step explanation:
Recall that:

We substitute the position vectors to get:

We subtract the corresponding components to obtain:

This gives:

This simplifies to:

The magnitude of a vector in the component form:

is

This means:

This simplifies to:


c) We have the vectors u = <4, 8>, v = <-2, 6>.
We want to find:
u+v
This implies that:
u+v=<4,8>+<-2,6>
We add the corresponding components to get;
u+v=<4+-2,8+6>
This simplifies to:
u+v=<2,14>
Answer:
speed = 
Step-by-step explanation:
using the formula that relates distance/ speed/ time
distance = speed × time
hence speed =
= 
I don't have my calculator handy. But use an online scientific calc. It will hold those digits. And most calculators tht are good will
8 hot dog buns per package
number of packages is 30
therefore number of hot dog buns = 30 x 8 = 240
hope this helps :P
