Avector v is in the direction of the vector 8i-6j and has magnitude 5. find v in the form ai+bj

4i - 3j.

Step-by-step explanation:

The slope of 8i - 6j = -6/8 = = -3/4 and the magnitude is √(8^2 + 6^2) = 10

So the required vector is 4i - 3j   ( with slope -3/4 and magnitude √(9+16) = 5).

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved
