trasher [3.6K]

Answer:

The answer is "26179.4".

Step-by-step explanation:

Assume year 2000 as t, that is  t =0.

Formula:

A= A_0e^{rt}

Where,

A_0 = \ initial \ pop \\\\r= \ rate \ in \ decimal \\\\t= \ time \ in \ year

for doubling time,

r = \frac{log (2)}{t} \\

r = \frac{\log (2)}{ 40} \\\\r= \frac{0.301}{40}\\\\r= 0.007

Given value:

A = A_0e^{rt} \\\\

A_0 = 13000

t= 40 \ years

when year is 2000, t=0 so, year is 2100 year as t = 100.

A = 13000 \times e^{et}\\\\A = 13000 \times e^{e \times t}\\\\A = 13000 \times e^{0.007 \times 100}\\\\A = 13000 \times e^{0.7}\\\\A= 13000\times 2.0138\\\\A = 26179.4

Answer:

Step-by-step explanation:

Kipish [7]

Answer:

675 gallons of syrup

96 cans

Step-by-step explanation:

Capacity of tank = 1,000 gallons

Danielle filled 65 5-gallon cans with syrup.

Gallons filled = 65 × 5 gallons

= 325 gallons of syrup

Gallons left in the tank = 1,000 - 325 gallons of syrup

= 675 gallons of syrup

3 12-packs Of regular cola = 3 × 12 packs = 36 packs

4 12- packs of diet cola = 4 × 12 packs = 48 packs

2 6-packs of orange soda = 2 × 6 packs = 12 packs

Total cans = 36 + 48 + 12

= 96 cans
