To factor 8x^2 + bx + 3, a student correctly rewrites the trinomial 8x^2 + px + qx + 3. What is the value of pq?
sergeinik [125]
Try this option:
1. if 8*x²+b*x+3=8*x²+p*x+q*x+3, then ⇒ b=p+q.
2. p*q = max_value (b²/2), if p=q=0.5*b, and p*q→-oo, if p>0 and q<0 or p>0 q<0.
3. example:
given 8x²+10x+3, the student rewrites it as a) 8x²+5x+5x+3 (5*5=25-max value); b) 8x²+0.01x+9.99x+3 (9.99*0.01=0.0999→0); c) 8x²-20x+30x+3 (p*q=-600).

answer: (-oo;0.5b²)

Water level in a well was 20m below ground level. During rainy season, rainwater collected in different water tanks was drained
IgorC [24]

Answer:

17 m

Step-by-step explanation:

As shown in the figure,  A_0-B_0 is the ground level, A_1-B_1 is the old level of water which was at 20 m below ground level, A_2-B_2 is the new level of water which is 5m above of old level. The height of wall of the well, 1.20 m, and the the pelly at 80 cm =0.80 m, has been shown too.

The minimum length of the rope is equal to the distance between the pully and the new water level, indicated by the length L_0 in the figure.

So, L_0= 20-5+1.20+0.80= 17m

Hence, Raghu must use a rope having the minimum length 17 m to draw water from the well.

Flura [38]

Answer:

  • 2/3

Step-by-step Solution:

Simply change the denominators such that both denominators are the same. Then, add the fractions to get your result.

  • 1/2 + 1/6
  • => 3 x 1/2 x 3 + 1/6
  • => 3/6 + 1/6
  • => 4/6 = 2/3

Hence, the solution is 2/3.
