The function f(x) = x2 + 10x – 3 written in vertex form is f(x) = (x + 5)2 – 28. what are the coordinates of the vertex?

(–5, –28)
(–5, 28)
(5, –28)
(5, 28)

Option A is correct

(–5, –28)

Step-by-step explanation:

For a quadratic equation:

We know that convert of quadratic into vertex form, using the method of completing the square is,

where,

(h, k) is the vertex.

As per the statement:

The function

written in vertex form is:

From the above definition we have;

h = -5 and k = -28

Therefore,  the coordinates of the vertex is, (-5, -28)

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
