The graph of a function has the vertex (-5,17) and passes through the point (-3,28) how do i write it in vertex form

y = -11/4 (x − h)² + k

Step-by-step explanation:

Vertex form of a parabola is:

y = a (x − h)² + k

where (h, k) is the vertex.

Given that the vertex is (-3, 28):

y = a (x + 3)² + 28

Given that a point on the curve is (-5, 17):

17 = a (-5 + 3)² + 28

-11 = 4a

a = -11/4

y = -11/4 (x − h)² + k

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.
