119. Beatrice decides to deposit $100 per month at the end of every month in a bank with an annual interest rate of 5.5% compoun
sveta [45]

Answer:

Beatrice will accumulate $1230.72 at the end of the year.

Step-by-step explanation:

We can write:

(1+\frac{0.055}{12})=z

100=C for deposits

The first month would have only the deposit reflected in her balance, then, expanding some steps of the calculation would yield:

S_{1}=C\\S_{2}=Cz + C\\S_{3}=Cz^{2}+Cz + C\\S_{n}=Cz^{n-1} +...+Cz+C

A geometric series is given by:

1+x+...+x^{m}=\frac{x^{m+1}-1}{x-1}

Translating our series to the short form:

S_{n}=C(\frac{z^{n}-1}{z-1} )

plugin in the values for the 12 month gives:

S_{12}=100(\frac{(1+\frac{0.055}{12})^{12} -1}{\frac{0.055}{12}})=1230.7169

Please help me :/
inessss [21]

Answer:

The answer to your question is:

Step-by-step explanation:

  m ∠ 1  = 27°

 m ∠ 1 and m ∠ 2 are supplementary

m ∠ 1 + m ∠ 2 = 180°

27° + m ∠2 = 180°

m ∠ 2 = 180° - 27°

m = 2 = 153°

Express the area of the entire rectangle. Your answer should be a polynomial in standard form.
disa [49]

The standard size of the rectangle's area is x² + 12x + 35

Given:

a diagram that depicts the polynomial that denotes a rectangle's length and width.

The rectangle's area is equal to its length x width.

Given that length is equal to x + 7 and width is equal to x + 5, the area is equal to length plus width.

Add the numbers in brackets: Area = x2 + 5x + 7x + 35

Area = x2 + 12x + 35

A quadrilateral with equal angles and parallel opposite sides is referred to as a rectangle. We are surrounded by numerous rectangular objects. The length and width of a rectangular shape are the two dimensions that define it. The rectangle's length and width are its longer and shorter sides, respectively. We will learn about the properties of the rectangle shape in this chapter.
