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.
Answer:
Answer:GCF: y^4
Step-by-step explanation:
Factors of:
y^4= (y) (y) (y) (y) = y^4 (1)
y^5 = (y) (y) (y) (y) (y) = y^4 (y)
y^6 = (y) (y) (y) (y) (y) (y) = y^4(y^2)
Hi there!
The answer is D. 21, 25, 29
The arithmetic sequence has a pattern of +4. From 17 you add 4, resulting to 21 and you continue.
Hope this helps !
Answer:
0
Step-by-step explanation:
f(x) = 2/5(6 - x)²
f(6) = 2/5[6 - (6)]²
f(6) = 2/5(0)²
f(6) = 0
