Answer:
At the time of launch height of the object was 60 meters.
Step-by-step explanation:
An object was launched from a platform and its height was modeled by the function,
h(x) = -5x² + 20x + 60
Where x = time or duration after the launch
At the time of launch, x = 0
So, by putting x = 0 in this equation,
h(0) = -5×(0) + 20×(0) + 60
h(0) = 60
Therefore, at the time of launch height of the object was 60 meters.

Answer:
E, F, B, and C
Step-by-step explanation:
Im just learning about these kind of things and this is a challenging question not going to lie.
I chose B because expanding and building more factories is apart of economics. You need more land to expand your business, but this will also affect the economy.
C seems like a good answer also because writing about economic trends is an important thing in economics. This also helps others learn out the economy and what not to do and what to do to help make our environment a better place.
I chose E because starting a business is apart of economics. A lot of business are apart of economic systems and help money come into our economy.
F is a good answer for me because the U.S government has been apart of America's economic system for a long time just like they are involved with everything else. The government is a big help and a big part of our economy, especially for america.
