Answer:
The cost of each tree is $95
Step-by-step explanation:
Let
x -----> the cost of each tree in dollars
we know that
The number of plants multiplied by the cost of each plant plus the number of trees multiplied by the cost of each tree must be equal to $964
so
Solve for x
subtract 204 both sides
Divide by 8 both sides
therefore
The cost of each tree is $95

Answer:
Geometric sequence
common ratio
5
Step-by-step explanation:
this is multiplying by 5 each time which means that it's a geometric sequence
because it's a geometric sequence that means it's called a common ratio
find the geometirc sequence by dividing the first one by the second
10/2=5
K value = natural log (.5) / half-life
half-life = natural log (.5) / k value
half-life = -.693147 / 0.1011
half-life =

I'd say the k value should be negative AND it should have units.
