Answer:
a= -2b
Step-by-step explanation:
math.
Answer:
Its probably a because the ones with squared results in a u shape
The given condition is an arithmetic sequence with the first term (a1) is 1 penny and the common difference (d) is 1 penny. A year that is not a leap year has 365 days (n). The arithmetic series (S) is calculated through formula,
S = (n/2) (2a1 + (n - 1) x d)
Substituting the known values,
S = (365/2) (2 x 1 + (365 - 1) x 1)
S = 66795 pennies
A dollar is 100 pennies. Therefore, at the end of the year, the total savings is $667.95.
You have to be able to know the appropriate properties or postulates to apply on the angles or segments to simplify them. An example would be the Angle Addition Postulate. This postulates states that the sum of the individual measures of the interior angles is equal to the measure of the included angle. There are still a lot more properties to choose from depending on the situation.
