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:
i dont want to put the whole example cz like ur school might catch u so u gonna have to do the explainin part srry:( but the answear is 156$
Step-by-step explanation:
I'm not completely sure, but this should be exponential growth.
If so, the equation for exponential growth is: y = a(1 + r)^t
If I substitute them with the information you gave me, then is would look like this:
y = 281.4(1 + 0.02)^t
**t = is the number of years after 2000 (based on your question)**

The relationship between temperature and the coffee sales is a negative exponential of temperature
<h3>
What is relation?</h3>
relation is subject of order between to sets or how the connected to each other.
The temperature of liquid is essential in the process of brewing because its affects the rate of evaporation or extraction. it refers to the test and matters that are dissolved from the coffee beans. The hot is the water, the quick it is to extract. At a high temperature, it’s tougher to control the rate of extraction. This can lead to over-evaporation of liquid, making your coffee taste too bitter since the heat strips away a lot of oxygen.
since the temperature varies over the year, which implies the taste of coffee also vary in a manner that in cold days people love coffees and in hotter days the people love to drink cold drinks instead of coffees
so in cold days the sales of coffees is grater in comparison with hot days
Thus the relationship between the sales of coffees and temperature is negative exponential of temperature.

Answer:
55%
Step-by-step explanation:
Divide 33 by 60 each percent is 1 2/3 so 30 is 50% and 3 is 5 50%+5%=55%
