In a geometric sequence, if a3 = ‒5 and a6 = 40, determine a1, r, and an. Then write the first three terms of the sequence.

Tresset [83]

$a_4=ra_3$
$a_5=ra_4=r^2a_3$
$a_6=ra_5=r^3a_3$

$40=-5r^3\implies r^3=-8\implies r=-2$

$a_3=ra_2=r^2a_1$

$-5=(-2)^2a_1\implies a_1=-\dfrac54$

You know the first and third terms, $a_1$ and $a_3$ , so you just need to find the second term $a_2$ :

$a_2=ra_1\implies a_2=-2\left(-\dfrac54\right)=\dfrac52$

Nick has designed a diamond shaped kite as shown below. The measures of some sides of the kite are marked in the figure. Find th

Zepler [3.9K]

Answer:

<h2>x = 3.499 in</h2>

Step-by-step explanation:

In a kite, the diagonals are perpendicular. Hence $\Delta DOC$ is a right angled triangle.

$DC=7\text{ }in,\text{ }OC=5\text{ }in$

From Pythagoras theorem, since $\Delta DOC$ is a right angled triangle, $DO^{2}+OC^{2}=DC^{2}$ .

Area of $\Delta DOC$ = $\frac{1}{2}\times base\times height$

$=\frac{1}{2}\times DO\times OC=\frac{1}{2}\times OP\times DC\\(2\sqrt{6})\times(5)=(7)\times(OP)\\OP=3.499\text{ }in$

From diagram $OP=x$

∴ $x=3.499\text{ }in$
