Find the center, vertices, and foci of the ellipse with equation

Step-by-step explanation:

since we can see that h and k is 0

therefore

c(0,0)

given:a²=100

let's find a

a=√100

a=10

therefore

vertices:(0±10,0)

=(0+10,0) and (0-10,0)

=(10,0) and (-10,0)

therefore,

foci:(h±c,k)

=(0±6,0)

=(0+6,0) and (0-6,0)

=(6,0) and (-6,0)

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.
