(x - 4)(x^2 + 3x + 2) =
x(x^2 + 3x + 2) - 4(x^2 + 3x + 2) =
x^3 + 3x^2 + 2x - 4x^2 - 12x - 8 =
x^3 -x^2 - 10x - 8
$1.00 - $.64 = 36 cents. You get 36 cents back in change.
V 1 = 500 mph,
v 2 = 50 mph
The resultant velocity:
v r² = v 1 ² + v 2 ²
v r ² = 500² + 50² = 250,000 + 2,500 = 252,500
v r = √252,500 = 502.49378 ≈ 502.49 mph
Answer: the magnitude of the resultant velocity is 502.49 mph.
Answer:
Step-by-step explanation: so you calculate how many people ate chicken, beef, fish or are vegetarian then you will add it all together
chicken=128
beef= 80
fish=32
vegetarian=112
128+80+32+112= 352 people ate at the restaurant
