To solve this answer we use the quadratic formula
which is: x = -b +- square root b^2 - 4ac / 2a
a=9
b=15
c= -14
then simply plug in,

-15 +- square root 15^2 - 4(15)(-14)/2(9)
( Honestly you can use a website called desmos for quadratics but this is how you do it by hand)
so , x= -2.333, x= 0.667

Solve for r <br> r/8 =7<br> r = ____

Nostrana [21]

Answer:

r=56

Step-by-step explanation:

Since, r divided by 8 gives 7, if you do the inverse function(which is basically like the reverse of the question)

you can multiply 8 and 7 to find the r.

So 8 times 7 gives 56.

And to check you can do

$\frac{56}{8}$ which gives 7

You can tell me if my explanation is wrong. Thanks

What is the recursive rule for this geometric sequence? 2, 1/2, 1/8, 1/32,

Sav [38]

$a_1=2,\ a_2=\dfrac{1}{2},\ a_3=\dfrac{1}{8};\ a_4=\dfrac{1}{32}\\\\r=\dfrac{a_2}{a_1}=\dfrac{a_3}{a_2}=\dfrac{a_4}{a_3}=...\\\\r=\dfrac{\frac{1}{2}}{2}=\dfrac{\frac{1}{8}}{\frac{1}{2}}=\dfrac{\frac{1}{32}}{\frac{1}{8}}=\dfrac{1}{4}\\\\\boxed{a_1=2;\qquad a_n=\dfrac{1}{4}\cdot a_{n-1}}$
