Find the perimeter of the scale artwork
P=2(l+w)
P=2(2.5+1.75)
=2(4.25)= 8.5 in
1 in = 0.5 ft
8.5in = 0.5(8.5)
=4.25ft = 51 in
the actual perimeter is 51 in or 4.25 ft
The angle between two vectors is:
CosФ = u - v / Magnitude(u) x magnitude(v)
Magnitude of u = SQRT(7^2 + -2^2) = SQRT(49 +4) = SQRT(53)
Magnitude of v = SQRT(-1^2 +2^2) = SQRT(1 +4) = SQRT(5)
u x v = (7 x -1) + (-2 x 2) = -7 + -4 = -11
cosФ = -11 / sqrt(53) x sqrt(5)
cosФ = -11sqrt265) / 265
Ф =cos^-1(-11sqrt265) / 265)
Ф=132.51 degrees.
2x + y = 0
2x + 3 = 0
- 3 - 3
2x = -3

x = -1¹/₂
(x, y) = (-1¹/₂, 3)

Answer:
132 minutes
Step-by-step explanation:
1 Km = (60)(8)+15=495 seconds
4 mornings = (495)(4) =1980 seconds
4 weeks = (1980)(4) = 7920 sec.
7920/60 = 132 minutes
