Vectors Question, Please Help!!

[From: ] [author: ] [Date: 11-05-30] [Hit: ]
2+t) on = b.t = -1/3(1 + 7√34)-Here: http://goodsyard.......
Determine the value of t such that the scalar projection of b = (1, 2 + t) on a = (5, -3) is 7

thank you and 10 points for best answer!!

scalar projection of (1, 2+t) on < 5, -3 > = b.a/II a II

=> (5 - 6 - 3t)/(√34) = 7

=> -1 - 3t = 7√34

-3t = 1 + 7√34

t = -1/3(1 + 7√34)
