a a car accelerates, then maintains its speed before speeding up again
Given:
Area of a rectangle = 4 square meters
wight = 1/5 meter
find the length
Area of a rectangle = length * width
length = area / width
length = 4 m² ÷ 1/5 m
length = 4 m² * 5/1m
length = 20 m
length is 20 meters.
Area = 20 m * 1/5 m = 20 m² / 5 = 4m²
It will take 15 years for the population to quadruple
Step-by-step explanation:
The formula for continuously compounding rate is , where
- A is the future amount
- P is the initial amount
- r is the interest as a decimal
- t is the time in years
Assume that the initial population is P
∵ The initial population = P
∵ The growth rate = 9% ⇒ compounded continuously
∴ r = = 0.09
∵ The population will quadruple in t years
∴ A = 4P
- Substitute these values in the formula
∵
∴
- Divide both sides by P
∴
- Insert ㏑ to both sides
∴ ㏑(4) = ㏑( )
∵ ㏑( ) = n
∴ ㏑ (4) = 0.09 t
- Divide both sides by 0.09
∴ t = 15.4
∴ t = 15 years to the nearest whole number
It will take 15 years for the population to quadruple
