Answer:
|F net| = 20.22 N
θ ≈ 19.8°
Step-by-step explanation:
F net = 15N i + 8cos(60°)N i + 8sin(60°)N j
= 15N i + 8×½N i + 8×√3/2N j
= 15N i + 4N i + 4√3N j
= 19N i + 4√3N j
|F net| = √(19²+(4√3)²) = √(361+48) = √409 ≈ 20.22N
tan(θ) = 4√3 ÷ 19 ≈ 0.36 → θ ≈ arctan(0.36) = 19.8°
Answer:
A
Step-by-step explanation:
Sum is the result of adding so
12 + x, but i don't see it as a option.
Answer: To find the volume of a cube, use the formula V=lwh, or Volume equals length times width times height.
<span>(4d-4)(3d-2)=12d^2 + []d + 8
Using FOIL method:
4d x 3d = 12d^2
4d x -2 = -8d
-4 x 3d = -12d
-4 x -2 = 8
Adding common terms, we have:
-8d + -12d = -20 d
The missing coefficient is -20.</span>
