Answer:
b. √x<-14
Step-by-step explanation:
square roots are never negative
(a) what are the x and y components of each vector?
For vector v1:
v1 = 6.6 (cos (180) i + sine (180) j)
v1 = 6.6 (-1i + 0j)
v1 = -6.6i
For vector v2:
v2 = 8.5 (cos (55) i + sine (55) j)
v2 = 8.5 ((0.573576436) i + (0.819152044) j)
v2 = 4.88 i + 6.96 j
(b) determine the sum v v 1 2
The sum of both vectors is given by:
v1 + v2 = (-6.6i) + (4.88 i + 6.96 j)
Adding component to component:
v1 + v2 = (-6.6 + 4.88) i + (6.96) j
v1 + v2 = (-1.72) i + (6.96) j
Answer:
Step-by-step explanation:
(x-3)(x-3)(x²)(x+2)
(x²-6x+9)(x³+2x²)
x^5+2x^4-6x^4-12x^3+9x^3+18x^2
x^5 - 4x^4 - 3x^3 +18x^2
(a-b)(2a+4b) = 2a² - 2ab + 4ab - 4b² = 2a² + 2ab - 4b²
