Let vector a = 3i + j - k.<br><br> Find the vector b in the direction of vector a such that |b| = 5

Serjik [45]

Answer:

5i +(5/3)j - (5/3)k

Step-by-step explanation:

Vector b is in the same direction as vector a, so it is a scalar multiple of a.

b = ca for some positive real number c.

b = c(3i + j - k) = 3ci + cj - ck

|b| = sqrt[(3c)^2 + c^2 - c^2] = sqrt(9c^2) = 3c

If |b| = 5, then 3c = 5 and c = 5/3

That makes b = (5/3)(3i + j - k) = 5i +(5/3)j - (5/3)k

Kaitaia has one more than 5 times the number or wristbands that shelly has. Rea has three more than twice the number that shelly

saul85 [17]

Answer: The required expression is 3x+4.

Step-by-step explanation:

Since we have given that

Let the number of wristbands that Shelly has be 'x'

Let the number of wristbands that Kaitaia has be $5x+1$

Let the number of wristbands that Rea has be three more than twice the number that shelly has be

$'2x+3'$

According to question, the expression that shows the number of wristbands more Katia has than Rea is given by

$5x+1-(2x-3)\\\\=5x+1-2x+3\\\\=3x+4$

Hence, the required expression is 3x+4.
