is a monomial.
In your case, the monomials are
As the name suggests, a trinomial is the sum of three monomials, which is exactly your case.
Answer:
7 seconds.
Step-by-step explanation:
We have been given that the height of a flare fired from the deck of a ship in distress can be modeled by , where h is the height of the flare above water and t is the time in seconds.
The ball will hit the ground, when height will be 0 meters, so we will equate to find the time when ball will hit the ground as:
Using quadratic formula, we will get:
Since time cannot be negative, therefore, it will take 7 seconds for the flare to hit the ground.
Answer:
12.5%
Step-by-step explanation:
sum the parts of the ratio 1 + 3 + 4 = 8 parts
8 parts represents 100%, hence
1 part = = 12.5% ← Andy's percentage of the total
