Answer:
First, we need to find how far ahead Marshall was. Since he had been biking at 20 mph for one hour, he had gone 20 miles.
Next, we need to find how long it will take Brett to catch up to Marshall. In order to do this, we need to find how much faster Brett is going than Marshall. We do this by subtracting Marshall's speed from Brett's speed.
60 - 20 = 40. So, Brett is catching up to Marshall at 40 mph. Now, we figure out how long it will take for someone going 40 miles per hour to go 20 miles. We find this by dividing 40 miles per hour by 20. This is equal to 1/2 hour. So, it will take Brett 0.5 hours to catch up to Marshall. This is the same as A, so A is the correct answer.
We can check our answer by seeing how far Marshall and Brett will have gone. Marshall will have been biking for 1.5 hours, so we multiply 20 * 1.5 = 30. Marshall went 30 miles.
Brett drove for .5 hours at 60 mph, so he went 30 miles. Since Brett and Marshall went the same distance, our answer is correct.
2^x is the function of the exponential growth.
Hence , 2^1, 2^2/hour = 4, 2^3 = 6/hr... 2^n=2^n at an amassing rate.
Bacteria is one great example to present the exponential growth. <span>Bacteria are single celled microorganisms. They have a simple cell structure than other organisms because they have no nucleus and no cell membrane. Their control center containing the genetic information si contained in a single loop of DNA. </span>

Step-by-step explanation:
if you meant for both of the y to be the same then this should be right
Answer: There are 13 slices when Dario cuts .
Explanation :
Since we have given that
Quantity of parmesan cheese is given by
Quantity of ricotta cheese is given by
Quantity of mozzarella cheese is given by
Now, total quantity of cheese Dario have
Now,
According to question, Dario cuts the lasagna into several equal slices and each containing exactly
So,
Number of slices is given by
Hence, there are 13 slices when Dario cuts .
