Given that function H(t) models the height of Pooja's plant (in centimeters) where t is the number of days after she bought it.
Now we have to find about which number type is more appropriate for the domain of h. That means what values can be taken by the variable "t".
Since t is number of days not the hours so t will not use decimal or fraction values. It can use integer values for the number of days.
Since time is counted after she bought the plant then number of days will be positive.
Hence answer for the type of domain can be positive integers or you can say integers greater than or equal to 0.
To solve this problem you must keep on mind the following information: By definition, a quadratic function has the following form:
Where
is the leading coefficient.
If the leading coeficient is closer to zero, the parabola is widest,if it has a larger positive or negative value, the parabola is narrowest.
Therefore, by knowing the information above, you have that
the answer is: 
Annual Social Security benefit = 0.42 x $37,991 = $15,956.22
Annual bills = $1,755 x 12 = $21,060
Outstanding annual bill to be settled after using the Social Security benefit = $21,060 - $15,956.22 = $5,103.78
Monthly supplementary money needed = $5,103.78/12 = $425.32
You cannot round on a calculator (at least the type I use). You need to learn how to do it yourself, if you are required to round to 3sf look at the 4th digit if it is greater than 5 you round the 3rd digit up and if the 4th digit is less than 5 leave the 3rd digit as it is

Answer:
C
Step-by-step explanation:
The period of a sine function can be found by looking at the argument.
In the equation y = Sin (ax), ax is the argument, and period is 360/a.
For the function shown, y = Sin x, the period is 360/1 = 360. This means that the period is the number of months it takes to complete one cycle of the graph (take one point in the graph and run along the curve until the same point is reached).
<em>If we take January as the first point (y = 40) and run along until i come to same point, we are back to next years' January. Hence, the period is 12 months. </em><em>Answer choice C is right.</em>
