<u>Given</u>:
The height of the bird at time t is given by the function 
We need to determine the time it takes the worm to be eaten by the bird.
<u>Time taken:</u>
The time can be determined by substituting h(t) = 0 in the function.
Thus, we have;

Switch sides, we get;

Let us solve the equation using the quadratic formula.
Thus, we get;

Simplifying, we get;



The values of t are given by
and 
and 
and 
Since, the value of t cannot be negative, then 
Thus, the time taken by the bird to eat the worm is
seconds.
Hence, Option B is the correct answer.
<h3>Volume of the cylinder:</h3>



<h3>Volume of the rectangular prism:</h3>



<h3>Total volume:</h3>


Answer:
600 centimeters. 1 meter is equal to 100 centimeters
Answer:
2047
Step-by-step explanation:
We are given that
Growing rate=0.7%



Using the formula



Initially when t=0,P=323 million
Substitute the values


Now, substitute P=400 million





Year=2016+31=2047
Hence,In 2047 the U.S population will reach 400 million people.
336 divided by 75 which equals 4.48
