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

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

ok then what happened.

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

hey there : ) your answer would be a.
