P=q+2 2p+3q=-26 help

Goshia [24]3 years ago

P=q+2 making 2p+3q=-26 become:

2(q+2)+3q=-26  perform indicated multiplication on left side

2q+4+3q=-26   combine like terms on left side

5q+4=-26  subtract 4 from both sides

5q=-30  divide both sides by 5

q=-6, and from earlier we know that p=q+2 so

p=-4

Thus (p,q)=(-4,-6)

All you have to do is plug and solve...

2(q+2) + 3q = -26
2q + 4 + 3q = -26

Subtract 4 from the left side and move it to the right...

 2q + 4 + 3q = -26
       - 4            - 04
_________________
2q + 3q = -30

Now add 3q and 2q together and you get 5q, next divide...

5q = -30
_______
5         5

Finally, you get q equal to negative 6 (-6)!

A 6m ladder leans against a wall. The bottom of the ladder is 1.3m from the wall at time =0sec and slides away from the wall at
icang [17]

Answer:

- 0.100

Step-by-step explanation:

Length of the ladder,  H = 6 m

Distance at the bottom from the wall, B = 1.3 m

Let the distance of top of the ladder from the bottom at the wall is P

Thus,

from  Pythagoras theorem,

B² + P² = H²    .

or

B² + P² = 6²          ..............(1)      [Since length of the ladder remains constant]

at B = 1.3 m

1.3² + P² = 6²

or

P² = 36 - 1.69

or

P² = 34.31

or

P = 5.857

Now,

differentiating (1)

2B(\frac{dB}{dt})+2P(\frac{dP}{dt})=0

at t = 2 seconds

change in B = 0.3 × 2= 0.6 ft

Thus,

at 2 seconds

B = 1.3 + 0.6 = 1.9 m

therefore,

1.9² + P² = 6²

or

P = 5.69 m

on substituting the given values,

2(1.9)(0.3) + 2(5.69) × (\frac{dP}{dt}) = 0

or

1.14 + 11.38 × (\frac{dP}{dt}) = 0

or

11.38 × (\frac{dP}{dt}) = - 1.14

or

(\frac{dP}{dt}) = - 0.100

here, negative sign means that the velocity is in downward direction as upward is positive
