A bird population is decreasing by 3 percent each year. Find the bird population after 6 years.

QveST [7]

Hello!

If it is decreasing by 3% each year, 18% of its population will have decreased after 6 years. As we do not have an original number, we will just say that the population is 18% less than the original.

If you want to find the exact number, multiply the original population by 0.18. Subtract the number from the original population.

I hope this helps!

starting from 1.4 miles away a car drives towards a speed check point and then passes it the car travels at a constant rate of 5

LenKa [72]

Answer: At t=0.015 hours when the car 0.6 miles from the check point.

Step-by-step explanation:

Since we have given that

Distance traveled by him towards a speed check point = 1.4 miles

Speed at which he is travelling = 52 miles per hour

Let the time taken by him be x

Since we have the equation

$d=1.4-52t$

where d denotes distance

and t denotes time.

If we have given that the car 0.6 miles from the check point.

So, we put the value of d in place of it .

$0.6=1.4-52t\\\\0.6-1.4=-52t\\\\-0.8=-52t\\\\0.8=52t\\\\\frac{0.8}{52}=t\\\\0.015=t$

So, at t=0.015 hours when the car 0.6 miles from the check point.
