Marvin can fun 52 KM in 6 Hours and 30 Min

First you divide 48 km /6 hours to find out how many km he ran per hour
48 km /6 hours = 8km/h
So you then multiply 8 km/h x 6.5 hours to find out how many km he ran in 6 hours and 30 mins.

What is f(x) = 7x2 42x written in vertex form? f(x) = 7(x 6)2 – 6 f(x) = 7(x 6)2 – 42 f(x) = 7(x 3)2 – 9 f(x) = 7(x 3)2 – 63.
ioda

The vertex form of the function f(x) is \rm f(x)= 7 ( x + 3 )^2 - 63.

<h2>Given </h2>

Function; \rm f(x) = 7x^2 + 42x

<h3>What is the vertex form of function?</h3>

The vertex of a parabola is the point at which the parabola passes through its axis of symmetry.

The standard equation which represents the vertex form of the function is;

\rm f(x) =(x-h)^2+k^2

Where h and k are vertexes of the given parabola.

The function is in vertex form;

\rm f(x)= 7 x^2 + 42 x\\\\ f(x) = 7 ( x^2+ 6 x ) \\\\ f(x)= 7 ( ( x^2+ 6 x + 9 ) - 9 ) \\\\ f(x)= 7 ( x + 3 )^2 - 63

Hence, the vertex form of the function f(x) is \rm f(x)= 7 ( x + 3 )^2 - 63.

To know more about the Vertex form lick the link given below.
