We write the generic exponential equation:
y = A (b) ^ t
Where,
A: initial population
B: growth rate
t: time in hours.
Substituting values we have:
y = 5 (2) ^ ((1 / 1.5) * t)
For t = 9 hours we have:
y = 5 (2) ^ ((1 / 1.5) * 9)
y = 320 million
For t = 24 hours (one day) we have:
y = 5 (2) ^ ((1 / 1.5) * 24)
y = 327680 million
For t = 2 hours we have:
y = 5 (2) ^ ((1 / 1.5) * 2)
y = 12.5992105 million
Answer:
a) t hours?
y = 5 (2) ^ ((1 / 1.5) * t)
b) 9 hours?
y = 320 million
c) 1 day?
y = 327680 million
d) 2 hours?
y = 12.5992105 million
Answer:
A
Step-by-step explanation:
Steps to take to determine the answer
- Because the length is in yards, it has to be converted to foot
- Find the area of the patio using the length and width measured in foot
- Determine the area of the square brick
- Multiply the cost of the brick by the area
1 yards = 3 foot
5 x 3 = 15 foot
Area of a rectangle = length x breadth
15 x 10 = 150 ft^2
Cost = 150 x 4 = $600
Answer:
40 + 40 + 125 + 125 + 200 + 200 = 730
Step-by-step explanation:you need to find the area of every square/rectangle in the figure, so 2 of the shapes are 8 x 5, 2 of them are 5 x 25, 2 of them are 8 x 25 getting you 730 mm^2
