The distance between cities A and B is 600 km. A train left A and headed towards B at 60 km/hr. Another train left B and headed

towards A at v km/hr. The trains met t hours after the time at which the first train left. Express v in terms of t.

Answer:

v = \frac{600-60t}{t}

Step-by-step explanation:

Let the trains A and B meet each other after t hours after the departure of a train A.

Distance traveled by train A in t hours (d_1) = Speed × time

                                                                      = 60 × t

Distance traveled by train B (d_2) = v × t

Since, Distance between the cities A and B = 600 km

d_1+d_2=600

60t + vt = 600

vt = 600 - 60t

v = \frac{600-60t}{t}

Therefore, expression that the represents the relation between v and t will be,

v = \frac{600-60t}{t}

Suppose that P(A) = 0.25 and P(B) = 0.40 . If P(A|B)=0.20 , what is P(B|A) ?
Ket [755]

Answer:

  • 0.32

Step-by-step explanation:

<u>Use of formula:</u>

  • P(A and B) = P(A)*P(B|A) and
  • P(A and B) = P(B)*P(A|B)

<u>According to above and based on given:</u>

  • P(A)P(B|A) = P(B)P(A|B)
  • P(B|A) = P(A|B)*P(B)/P(A)
  • P(B|A) = 0.20*0.40/0.25 = 0.32

Factor completely 2x3 + 8x2 + 3x + 12.
goblinko [34]

Answer:

(2x^2+3)(x+4).

Step-by-step explanation:

2x^3+8x^2+3x+12

We need to find the factors of given equation;

Solution:

On Solving the above equation we get;

Now First we will take common factor from first 2 terms which is 2x^2 we get;

2x^2(x+4) + 3x+12

Now we will take the common factor from the last 2 terms which is 3 we get;

2x^2(x+4) + 3(x+4)

Here we get 2 terms in which (x+4) is common factor.

(x+4)(2x^2+3)

Hence After factorizing the given equation we get (2x^2+3)(x+4).
