Take the 89 times 5 tests. You get 445 total score you need for an average of 89.  Add 82, 89, 92, 87=350 445-350=95  They must get a 95 on next test to get the average of 89

nadya68 [22]
For 3 days....

option 1 : 25(3) + 0.10m = 75 + 0.10m
option 2 : 60(3) = 180

180 < 75 + 0.10m
180 - 75 < 0.10m
105 < 0.10m
105 / 0.10 < m
1050 < m.....this is minutes, we need hrs
1050/60  < m
17.5 < m.......the guest would have to spend more then 17.5 hrs

A minimum-phase continuous-time system has all its poles and zeros in the left-half s-plane. If a minimum-phase continuous-time
vlabodo [156]

Answer:

Yes, a minimum phase continuous time system is also minimum phase when converted into discrete time system using bilinear transformation.

Step-by-step explanation:

Bilinear Transform:

In digital signal processing, the bilinear transform is used to convert continuous time system into discrete time system representation.

Minimum-Phase:

We know that a system is considered to be minimum phase if the zeros are situated in the left half of the s-plane in continuous time system. In the same way, a system is minimum phase when its zeros are inside the unit circle of z-plane in discrete time system.

The bilinear transform is used to map the left half of the s-plane to the interior of the unit circle in the z-plane preserving the stability and minimum phase property of the system. Therefore, a minimum phase continuous time system is also minimum phase when converted into discrete time system using bilinear transformation.

Line A is represented by the following equation:
Vesnalui [34]
- for line B so the set of equations to have no solutions bc. x+y=2 and so y=2-x 
so from x+y=4 will result y=4-x

so this is the right equation for line B so the set of equations has no solutions
