Which ordered pair would be a solution on the graph of the following system of inequalities: y is greater than or equal to negat

daser333 [38]

Ordered pair is $( x, y)= ( \frac{20}{17} , \frac{-126}{17} )$

Step-by-step explanation:

We have the following inequalities:

$y \geq \frac{-x}{2} - 8$ and $y < 8x +2$ . In order to find ordered pair would be a solution on the graph .Let's solve both inequalities , and will take common solution from both of them !

$y = \frac{-x}{2} - 8 \\$ and , $y = 8x +2$ which implies:

⇒ $8x + 2 = \frac{-x}{2} - 8$

⇒ $\frac{17x}{2} = - 10$

⇒ $x = \frac{-20}{17}$

putting value of x in both inequalities we get,

$y \geq \frac{-x}{2} - 8$ and $y < 8x +2$

$y \geq \frac{-(\frac{-20}{17} )}{2} - 8$ and $y < 8.(\frac{-20}{17}) + 2$

$y \geq \frac{-126}{17}$ and $y < \frac{-126}{17}$

Hence at x = $\frac{-20}{17}$ and y = $\frac{-126}{17}$ above inequalities are satisfied. ∴ Ordered pair is $( x, y)= ( \frac{20}{17} , \frac{-126}{17} )$

Given () = −^3 + 2^2 +(3/2) be the position of a particle moving along the x-axis at time t. At what time will the instantaneous

cestrela7 [59]

Answer:

5.266 secs

Step-by-step explanation:

Lets assume ; p(t) = t^-3 + 2^2 + ( 3/2 ) is the particle position along x-axis

time interval [ 0, 4 ]

Average velocity = Displacement / time

= p( b ) - p( a ) / b - a -------- ( 1 )

where a = 0 , b = 4 ( time intervals )

Back to equation 1

Average velocity = [ ( 4^-3 + 4 + (3/2) ) - ( 0 + 4 + (3/2) ) ] / 4

= 3.9 * 10^-3 ----- ( 2 )

Instantaneous velocity = d/dx p(t)

= - 3/t^4 ------ ( 3 )

To determine the time that the instanteous velocity = average velocity

equate equations (2) and (3)

3.9*10^-3 = - 3 / t^4

t^4 = - 3 / ( 3.9 * 10^-3 ) = - 769.231

hence t = $\sqrt[4]{- 769.231 }$ = 5.266 secs

we ignore the negative sign because time can not be in the negative
