A function table with six rows and two columns is shown. The two boxes in the first row on the top, from left to right have the entries x and f open parenthesis x closed parenthesis. The second row has the entries three and negative three point five. The third row has the entries four and a blank box. The fourth row has the entries five and five point five. The fifth row has the entries six and ten. The last row has entries seven and fourteen point five. A linear function f(x) is shown in the table. What is the value of f(4) ?

f(4)=

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

whats the

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.
