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}  )

<u>Step-by-step explanation:</u>

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
