Nswer:ne square mile of forest is divided up into ten equally sized quadrats, 1/10th of a mile each. In quadrat #3, twenty-five pine trees are counted. What would be a reasonable estimate for the total number of pine trees in the larger plot of land (one square mile or forest)? 2 SEE ANSWERS 250 pine trees

Explanation:

If we have a one square mile of forest that is divided into ten equally sized quadrants, that means that each of them accounts for 1/10th of a mile. If in one of the quadrants there are twenty-five pine trees, and if that is the number of pine trees in all of the quadrants, then we can easily come to the result for the whole forest. As each quadrant is 1/10 of the whole area, it means that the number of pine trees in one of them should be multiplied by the number of quadrants:

25 x 10 = 250

We get a result of 250 pine trees for the whole forest area of one square mile.

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
