POLYNOMIAL 1) If one zero of f(x)is -4, then the other zeros of f (x)=3x^3+17x^2+18x−8 are: 1) 1/3, 2
2) -1, 2/3
3) 1/3, -2
4) - 1/3, 2 (it's -1 and 3 not just the 1)

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8

it has to have an angle of 90 degrees
