Solve x2 + 5x = −6. (6 points)
Damm [24]

Answer:

<em><u>x = -0.5</u></em><em> </em>

Step-by-step explanation:

<em>You need to combine like terms</em>

x * 2 + 5x = -6

<em>Add x to 5x</em>

6x * 2 = -6

<em>Divide 2 from both sides</em>

6x = -3

<em>Divide 6 from both sides to get x alone</em>

x = -0.5

<em>Hope this helps</em>

The sum of the first 6 terms of a geometric sequence is 7, 812. the common ratio is 5. what is the second term of the sequence?
Snezhnost [94]
OH right! I should have realised that!

S6 =  7,812 = a1 * (5^6 - 1)
                               -----------  were  a1 = first term
                                 5 -  1

3906*a1 = 7812
a1 = 7812 / 3906 =  2

Therfore the second term = 2*5  = 10 Answer

The volume of this cylinder is 2,034.72 cubic inches. What is the radius?
jasenka [17]

\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ V=2034.72\\ h=18 \end{cases}\implies 2034.72=\pi r^2(18) \implies \cfrac{2034.72}{18\pi }=r^2 \\\\\\ \cfrac{2034.72}{18(3.14) }=r^2\implies \sqrt{\cfrac{2034.72}{18(3.14) }}=r\implies 6=r
