Vadim26 [7]

Hence the answer is 480ml

Step-by-step explanation:

Given Elena wonders how much water it will take to fill her cup. She drops her pencil in the cup and notice it just fit diagonally. The pencil is 17cm long (hypotenes) and the cup is 15cm tall.

To find how much water it can hold

SOLUTION

s

\sqrt{x {} ^{ 2}  + x {}^{2}  + 15 {}^{2}  = 17 }

2x {}^{2}  = 64

x {}^{2}  = 32

x = 5.66

therefore volume of the cup

5.66 \times 5.66 \times 15cm|

480cm³= 480ml

Find the sum of the first five terms using the geometric series formula for the sequence left curly bracket 1 half comma space m
MatroZZZ [7]

Answer:

\bold{\dfrac{11}{2 }}

Step-by-step explanation:

Given the geometric series:

\{\dfrac{1}2, -1, 2, -4,  ..... \}

To find:

Sum of series upto 5 terms using the geometric series formula = ?

Solution:

Formula for sum of a n terms of a geometric series is given as:

S_n=\dfrac{a(1-r^n)}{1-r} \ \{r

a is the first term of the geometric series

r is the common ratio between each term (2nd term divided by 1st term or 3rd term divided by 2nd term ..... ).

Here:

a = \dfrac{1}{2}

r = \dfrac{-1}{\dfrac{1}{2}} = -2

n=5

So, applying the formula for given values:

S_5=\dfrac{\dfrac{1}2(1-(-2)^5)}{1-(-2)} \\\Rightarrow S_5=\dfrac{1-(-32)}{2 \times 3} \\\Rightarrow S_5=\dfrac{1+32}{6} \\\Rightarrow S_5=\dfrac{33}{6} \\\Rightarrow \bold{S_5=\dfrac{11}{2}}

So, the answer is

\bold{\dfrac{11}{2 }}
