Answer:

$- 0.6 \leqslant x \leqslant 0.666 \: and \: x > \sqrt[3]{7}$

Step-by-step explanation:

The answer you are saying is correct if it was an equation

In inequalities the answer most of the times comes in ranges

The easiest way to find the range is by graphing the equation and finding the values of x for which the graph is above the x axis

There is a good graphing calculator app called desmos if u don't have one

98. What is the sum of the first 27 terms in the arithmetic series 25 +19+13 + ...?

jeka57 [31]

Answer:

sum of the first 27 terms = -1431

Step-by-step explanation:

<h3>arithmetic series sum of the first n terms formula:</h3>

$s_{n} = \frac{n}{2} (2a + (n - 1)d)$

n = 27 terms

first term, a = 25

common difference, d = 19 - 25 = -6

substitute the values into the formula

$s_{27} = \frac{27}{2} (2(25) + (27 - 1)( - 6))$

$s_{27} = 13.5(50 + 26( - 6))$

$s_{27} = 13.5(50 - 156)$

$s_{27} = 13.5( - 106)$

$s_{27} = - 1431$

Find the value of d that makes the equation true:

hichkok12 [17]

To answer this, you need to get "d" on one side by itself. To do this, add 8 to both sides of the equation.

d- 8 + 8 = 5 + 8
-8 and +8 cancel out leaving:
d = 13

Your answer is d = 13
