Answer:
Step-by-step explanation:
Given A = 5i + 11j – 2k and B = 4i + 7k, the vector projection of B unto a is expressed as 
b.a = (5i + 11j – 2k)*( 4i + 0j + 7k)
note that i.i = j.j = k.k =1
b.a = 5(4)+11(0)-2(7)
b.a = 20-14
b.a = 6
||a|| = √5²+11²+(-2)²
||a|| = √25+121+4
||a|| = √130
square both sides
||a||² = (√130)
||a||² = 130
<em>Hence the projection of b unto a is expressed as </em><em></em>
You will divide 50 by 10 to get 5. Then multiply 5 by 50 to get 250
The population of Saya islands after 4 months will be 8,100 people.
It is given in the question that:-
Initial population of Saya island = 100 people
The population of the Saya island tripled every month
We have to find the population of the island after 4 months.
The population of Saya island after 1 month = 100*3 = 300 people.
The population of Saya island after 2 months = 300*3 = 900 people.
The population of Saya island after 3rd months = 900*3 = 2,700 people.
The population of Saya island after 4th months = 2700*3 = 8,100 people.
