Answer:

$\mathrm{D.} \: (\frac{5}{4} )^{\frac{7}{2}$

Step-by-step explanation:

$\sqrt{(\frac{5}{4})^7 }$

Apply rule : $\sqrt{a} =a^{\frac{1}{2} }$

$((\frac{5}{4})^7 )^{\frac{1}{2} }$

Apply rule : $(a^b)^c=a^{bc}$

$(\frac{5}{4} )^{7 \times \frac{1}{2} }$

$(\frac{5}{4} )^{\frac{7}{2}$

Find the sum of the first six terms of a geometric progression .

Dominik [7]

Question:

Find the sum of the first six terms of a geometric progression.

1,3,9,....

Answer:

$S_6 = 364$

Step-by-step explanation:

For a geometric progression, the sum of n terms is:

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

In the given sequence:

$a = 1$

$r = 3/1 =3$

$n = 6$

So:

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

$S_6 = \frac{1 * (3^6 - 1)}{3 - 1}$

$S_6 = \frac{3^6 - 1}{2}$

$S_6 = \frac{728}{2}$

$S_6 = 364$

Find the altitude of the triangle with a side of 18.<br> Put into sqrt.

ira [324]

Step-by-step explanation:

BD = DC = 1/2 BC ---> AD is median ( because in equilateral triangle altitude equals to median )

so, therefore

AB = 18 (given)

BD = 1/2 BC

BD = 1/2 × 18

BD = 9

AB² = AD² + BD² ---( by pythagoras theorm)

18² = AD² + 9²

324 = AD² + 81

324 - 81 = AD²

243 = AD²

then,

AD = √243

AD = 15 58
