Someone please help, 5500 trees were planted in a forest on 1st october 2018. only 5060 of these trees were still alive on 1st october 2019. it is assumed that the number of trees still alive is given by n=ar^t where N is the number of tree still alive T years after 1st October 2018.
Write down the value of a
Work out the value of r
Work out the predicted percentage decrease in trees still alive between 1st October 2018 and 1st October 2030

5104.38 inches

step-by-step explanation:

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
