Answer:
y = -1/3x + 12/5
Step-by-step explanation:
The maximum height is 144 feet.
The maximum height is the y-coordinate of the vertex. To find the vertex, we first use x = -b/2a. For our information, that is x=-64/2(-16) = -64/-32 = 2.
Now we substitute this into the equation:
y = -16(2²) + 64(2) + 80 = -64 + 128 + 80 = 144
Answer:
6045000000000000000000000 kg.
Step-by-step explanation:
We have been given that the mass of Earth is kg. The mass of the Moon is kg.
To find the total mass we will add mass of Earth and Moon.
First of all let us convert the given masses in standard form.
Therefore, the mass of Earth and Moon is 6045000000000000000000000 kg.
