Answer:
The answer to your question is below
Step-by-step explanation:
See the picture, please
In the first picture, we notice the initial amount of brownies (7/10), 7 brownies in a pan for 10 brownies.
After Tyreese bought 2/5 (7/10 - 2/5 = 3/10) there are 3 brownies left.
So in the picture, we notice only 3 brownies in a pan for 3 brownies.
The height of an object can be represented as a function of time.
It takes the rocket 25 seconds to hit the ground
The height function is given as:
When the rocket hits the ground, we have:
h(t) = 0
So, the height function becomes
Rewrite as:
Divide both sides by 16t
Hence, it takes the rocket 25 seconds to hit the ground
