Answer:
3x^2-6x -3
Step-by-step explanation:
(2x^2-5x+1)+(x^2-x-4)
we sum all coefficient according to the exponent of the variable
2x^2-5x+1+x^2-x-4 = 3x^2-6x -3
The summary of directions of the parabola is:
a) Squared term is x
Parabola either opens up or down.
Positive coefficient means upward opening and negative coefficient means downward opening
b) Squared term is y
Parabola either opens right or left
Positive coefficient means rightwards opening and negative coefficient means leftwards opening
Since the coefficient is positive with squared x term, the parabola opens upward.
So the answer to this question is option D
The relation between pressure and volume is given as
v = 18000/p
where
v = volume, in³
p = pressure, lb/in²
When the pressure is p = 900 lb/in², then the volume is
v = 18000/900 = 20 in³
Answer: 20 in³
Answer: 60
Step-by-step explanation:
9/15 = 0.6 = 1% 1% x 100 = 100% so 0.6 x 100 = 60
