Answer:

b. \frac{40}{3}

Step-by-step explanation:

The given geometric series is;

20-10+5-\frac{5}{2}+...

The first term of this series is

a_1=20

The common ratio is

r=\frac{-10}{20}=-\frac{1}{2}

The sum to infinity of this series is

S_{\infty}=\frac{a_1}{1-r}

Substitute the given values to obtain;

S_{\infty}=\frac{20}{1--\frac{1}{2}}

This implies that;

S_{\infty}=\frac{20}{\frac{3}{2}}

S_{\infty}=\frac{40}{3}

kolezko [41]

Answer:

\$\ 25

Step-by-step explanation:

By definition, the absolute error is defined as:

\epsilon = |x_a - x_e|

Where:

\epsilon: is the error

x_a: is the approximate value

x_e: is the exact value

In this problem the approximate value was 100 and the exact value was 75. Then we substitute these values in the formula to find the error.

\epsilon = |100 - 75|\\\epsilon = \$\ 25
