Evaluate the series 4 – 2 + 1 – 0.5 + 0.25 to S10. Round to the nearest hundredth.

aleksklad [387]

The initial term of this geometric series is 4, and the common ratio is -1/2. The sum is given by

$S_{n}=a_{1}\dfrac{r^{n}-1}{r-1}\\\\S_{10}=4\cdot \dfrac{(-\frac{1}{2})^{10}-1}{-\frac{1}{2}-1}=4\cdot \dfrac{(\frac{1}{1024}-1)}{(-\frac{3}{2})}\\\\=\dfrac{8}{3}\cdot \dfrac{1023}{1024}=\dfrac{341}{128}$

The sum is approximately 2.66.

Evaluate 24 + |x - 4| - y if x=2 and y= -3 Help me plz

Sonja [21]

Answer:

$\huge \boxed {29}$

Step-by-step explanation:

$24 + |x - 4| - y$

Given x = 2 and y = -3. Therefore, substitute x = 2 and y = -3 in the expression.

$24 + |2 - 4| - ( - 3) \\ 24 + | - 2| + 3$

Multiplying the negative with negative equal positive. All negative numbers in the absolute will become positive.

$24 + 2 + 3 = 24 + 5 = 29$

Therefore the answer is 29.

Step-by-step explanation:

To find the y-coordinate points we need to evaluate the function for all the $x$ values in the table. In other words, we need to replace $x$ with each value in our given function and simplify.
