Question

[25 POINTS] hi um please send help within like, 20 mins bc I'm gonna cry hahahaha

determine a value of c such that cu = 75 where u = 7i + 24j

context: precalc, vector unit

Answer 1

I will cry with you

Answer 2

c = 3

c = -3

(There are two because absolute value :P)

Explanation:

u = 7i + 24j

u = (7, 24)

||c * u|| = 75

75 = || c
`\sqrt{7^(2)+24^(2) }` ||

75 = || c
`√(625)` ||

75 = || c * 25 ||

3 or -3 = c
