Use the quadratic formula to solve 5x^2+2x-3

Lisa [10]

Assuming it equals 0
for
ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^2-4ac} }{2a}$

given
5x^2+2x-3=0
a=5
b=2
c=-3

x= $\frac{-2+/- \sqrt{2^2-4(5)(-3)} }{2(5)}$
x= $\frac{-2+/- \sqrt{4+60} }{10}$
x= $\frac{-2+/- \sqrt{64} }{10}$
x= $\frac{-2+/- 8 }{10}$
x=(-2+8)/10 or (-2-8)/10
x=6/10 or -10/10
x=3/5 or -1

If the 11th term of a geometric sequence is 32 times larger than the 6th term, then

mojhsa [17]

Answer:

r = 2

Step-by-step explanation:

nth term of a geometric sequence = $ar^{n - 1}$ .

Where,

a = first term, r = common ratio,

We are given that, the 11th term is 32 times larger than the 6th term of the geometric sequence. Thus:

the 6th term can be expressed as $ar^{n - 1} = ar^{6 - 1}$

$a_6 = ar^{5}$

The 11th term is expressed as $a_11 = ar^{10}$

Since the 11th term is 32 times larger than the 6th term, therefore, the following equation can be derived to find the common ratio, r, of the sequence:

$a_11 = 32*a_6$
