Answer:
8(3-(-1)) = 32
Step-by-step explanation:
Answer:
Step-by-step explanation:
we know that
The equation of a exponential growth is equal to
where
a is the initial value
r is the rate of growth
x is the time in hours
y is the value of the quantity
we have
substitute
For x=22 hours
substitute
It will be $3.68 for each rose bush because if she bought 6 of them for $22.08 then 22.08/6=3.68
Let the width of the frame = x
Let the cost of a linear foot of the frame = y
Let the inside dimension of the length of the frame = a
Let the inside dimension of the width of the frame = b.
The total length of the frame = 2*a + 4x
The total width of the frame = 2b
The total amount of the frame in feet is (2a + 4x + 2b)*y = Cost
