Answer:
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)
Answer:
39.96 miles
Step-by-step explanation:
The first step is to find how long he drove in yards. yards. Now, we need to convert it into feet. A yard is exactly three feet, meaning that he drove feet. Finally, we need to find how many miles he drove. It is known that there are 5280 feet in a mile, so you just need to divide the number of feet he drove by the number of miles to find that he drove 210998.8/5280=39.96 miles. Hope this helps!
