Answer:
0.3
Step-by-step explanation:
Answer:
y = - 4/5x - 1 2/5 Step-by-step explanation:
(-3, 1) (1, -2)
-2 - (-1) / 1 - (-3) = -1/4
Answer:
Step-by-step explanation:
3x/x^ 2 - 6x = 1
3/x - 6x = 1
Multiply each term by x
3 - 6x² = x
6x² + x - 3 = 0
Using quadratic formula
X = [-b ± √(b² - 4ac)]/2a
a = 6, b = 1 and c = -3
X = [-1 ± √(1² - 4(6×-3)]/(2×6)
X = [-1 ± √(1 +72)]/12
X = [-1 ± √73]/12
X = [-1 ± 8.54]/12
X = (-1 + 8.54)/12 or (-1 - 8.54)/12
X = 7.54/12 or -9.54/12
X = 0.63 or - 0.8
Answer:
mass=180kg and the volume=6m³.
then the formula to find density is= mass/volume
using this formula,180kg/6m³=30kg/m³
