Answer: The population would be 6580 after 7 years.
Step-by-step explanation:
The growth rate is exponential. We would apply the formula for exponential growth which is expressed as
y = b(1 + r)^ t
Where
y represents the population after t years.
t represents the number of years.
b represents the initial population.
r represents rate of growth.
From the information given,
b = 5000
r = 4% = 4/100 = 0.04
t = 7 years
Therefore
y = 5000(1 + 0.04)^7
y = 5000(1.04)^7
y = 6580
Answer:
500 miles
Reason:
On its first flight, it flew away 1000 miles away from London but flew 500 miles towards London on its second flight.
1000 miles - 500 miles = 500 miles :)
2x^2+4x-6=0
(2x^2+6x)(-2x-6)
2x(x+3) -2(x+3)
(2x-2)=0 (x+3)=0
x= 1 x=-3
Answer:
A
Step-by-step explanation:
simple interest
1000 x 6.4% x 5 = 320
compound int
1000(1+12.8/100)^5 - 1000=826.188
Answer:
It will take 2.6 hours by Daniel to catch up with Frank.
Step-by-step explanation:
Let Daniel will catch up with Frank after t hours.
Now, Frank will go 13 miles in 
hours.
So, the distance traveled by Frank in (t + 0.228) hours with 45 mph speed will be equal to the distance traveled by Daniel in t hours with 50 mph speed.
Hence, 45(t + 0.288) = 50t
⇒ 5t = 13
⇒ t = 2.6 hours.
Therefore, it will take 2.6 hours by Daniel to catch up with Frank. (Answer)
