Answer:
The first one is 12.5 weeks.
Step-by-step explanation:
A) 4a - 3b + 2c
4(2, -1, 5) - 3(4, 3 , -2) + 2(5, 4, 0) = (8, -4, 20) - (12, 9, - 6) + (10, 8, 0) =
= (8 - 12 + 10 , -4 - 9 + 8 , 20 + 6 + 0) = (6, - 5, 26)
Answer: (6, - 5, 26)
b) magnitude of vector b

c) vector of length 7 parallel to vector c
=> m(5,4,0) = (5m,4m,0)
=>

=> m = 7 / √41 ≈ 1.093
=> 1.093 (5, 4, 0) = (5.465 , 4.372, 0)
Answer: (5.465 , 4.372 , 0)
Answer:
x-int: (-2,0)
y-int: (0,1.333)
Step-by-step explanation:
6y - x = 12 //Solve for y.
6y = x + 12
y = x/6 + 2
Slope = m = 1/6
For the second which is perpendicular to line one has a slope of -6.
NOTE: Perpendicular line has negative reciprocal slope. 1/6 negative reciprocal would be -6.
Second line:
m = -6
point = (-1,2)
y - y1 = m(x - x1) //Plug in m and point in place of (x1,y1).
y - 2 = -6(x - -1)
y - 2 = -6x -6
y = -6x -6 +2
y = -6x - 4
