Answer:
a. <-28, -8>
Step-by-step explanation:
The given vector is
u = <-7, -2>.
To find 4u, we multiply the given vector by the scalar 4.
4u =4 <-7, -2>.
4u =<-7\times4, -2\times4>.
We multiply out to get;
4u =<-28, -8>.
The correct choice is a. <-28, -8>
15,000 - 2,500
=12,500 + 3,000
=15,500 - 1,000
=14,500 + 2,500
=17,000 - 3,000
=14,000 ft after 2 hours
Answer:
2.36 * 10^13 miles
Step-by-step explanation:
Given that :
Proxima centauri is at a distance of 4.24 light years away from the sun.
Distance in miles of Proxima centauri from the sun ;
1 light year = 5.9 * 10^12 miles
Number of light years from the sun * 5.9 * 10^12
= 4 * (5.9 * 10^12)
= 23.6 * 10^12 miles
= 2.36 * 10^13 miles
