A) <span>The mass of the air freshener A decreases by 3.2 grams each day. Define a function, f, to represent this situation.
In this function, the mass of the air freshener A (m) is the dependent variable and the days (t) and the initial amount of the air freshener A (mi) are the independent variables. If the mass decreases by a fixed amount each day, you only have to multiply this amount by the number of days:
</span>
<span>B) The mass of the air freshener B decreases by 3.2% each day. Define a function, g, to represent this situation.
</span>
This function is trickier since there isn't a fixed amount of decreasing. Instead, the rate of decreasing depends on the initial amount of the freshener (mi). You have to include this initial amount in the equation to correctly model it. This is how you do it:
Have a nice day!

Answer:
Therefore the length of EC is 6.67 ft.
Step-by-step explanation:
Given:
BC = 12 ft
AC = 6.75 ft
DE = 3ft
DE is parallel to AC.
Angle C is 60°.
Angle A and Angle BDE are both right angles.
Triangle ABC is similar to Triangle DBE.
To Find:
EC = ?
Solution:
Δ ABC ~ Δ DBE ..................Given
If two triangles are similar then their sides are in proportion.
On substituting the given values we get
Now as B - E - C,
..........Addition property
substituting the given values we get
Therefore the length of EC is 6.67 ft.
