1 answer:

3 0

To solve this problem you can apply the proccedure shown below:
1. You have the fexpression given in the problem above, which you can rewrite it as following:
-4√(9/2x)
2. You can find an equivalent expression:
-4√(3²/2x)
(-4)(3)√(1/2x)
-12/√2x
3- If you multiply the numerator and the denominator by √2, you obtain:
(-12√2)/[(√2)²√x]
(-12√2)/(2√x)
(-6√2)/(√x)
Therefore, the answer is:-(-6√2)/(√x)

A = 1011 + 337 + 337/2 +1011/10 + 337/5 + ... + 1/2021

The sum of the given series can be found by simplification of the number

of terms in the series.

A is approximately 2020.022

Reasons:

The given sequence is presented as follows;

A = 1011 + 337 + 337/2 + 1011/10 + 337/5 + ... + 1/2021

Therefore;

$\displaystyle A = \mathbf{1011 + \frac{1011}{3} + \frac{1011}{6} + \frac{1011}{10} + \frac{1011}{15} + ...+\frac{1}{2021}}$

The n + 1 th term of the sequence, 1, 3, 6, 10, 15, ..., 2021 is given as follows;

$\displaystyle a_{n+1} = \mathbf{\frac{n^2 + 3 \cdot n + 2}{2}}$

Therefore, for the last term we have;

$\displaystyle 2043231= \frac{n^2 + 3 \cdot n + 2}{2}$

2 × 2043231 = n² + 3·n + 2

Which gives;

n² + 3·n + 2 - 2 × 2043231 = n² + 3·n - 4086460 = 0

Which gives, the number of terms, n = 2020

$\displaystyle \frac{A}{2} = \mathbf{ 1011 \cdot \left(\frac{1}{2} +\frac{1}{6} + \frac{1}{12}+...+\frac{1}{4086460} \right)}$

$\displaystyle \frac{A}{2} = 1011 \cdot \left(1 - \frac{1}{2} +\frac{1}{2} - \frac{1}{3} + \frac{1}{3}- \frac{1}{4} +...+\frac{1}{2021}-\frac{1}{2022} \right)$

Which gives;

$\displaystyle \frac{A}{2} = 1011 \cdot \left(1 - \frac{1}{2022} \right)$

$\displaystyle A = 2 \times 1011 \cdot \left(1 - \frac{1}{2022} \right) = \frac{1032231}{511} \approx \mathbf{2020.022}$

A ≈ 2020.022

-114=-5x-2(4x+18) ????????

SVETLANKA909090 [29]

Primeiro multiplica o -2 com tudo que tem dentro do parenteses (chuveirinho) -114 = -5x -2(4x+18)

-2 . 4x = -8x + -2 . 18 = -36 = -8x-36

Agora soma os números com incógnitas (no caso x)

-114 = - 5x - 8x -36

Joga a incógnita do outro, tornando positiva

-114 = -13x - 36

13x -114 = -36

e o 114 do outro lado, ficando positiva também

13x -114 = -36

13x = - 36 + 114

13x = 78

x = 78 /13

x= 6
