Answer:
-8
Step-by-step explanation:
Common ratio of a geometric sequence can be obtained by dividing the successive terms as ,
=> S = 11 , -88 , 704
=> r = -88/11
=> r = -8
OR
=> r = 704/-88
=> r = 8/-1
=> r = 8(-1)/(-1)(-1)
=> r = -8
<h3>• Hence the common ratio is -8.</h3>
Answer:
20(pie)
Step-by-step explanation:
Since the circumference of a circle is 20 feet, the formula for circumference is 2r(pie) with r=radius
(radius)2=diameter
(diameter)(pie)
20(pie)
Answer:
-7/4
Step-by-step explanation:
8x=-14
X=-14/8
X=-7/4
In a quadratic equation
q(x) = ax^2 + bx + c
The discriminant is = b^2 - 4ac
We have that discriminant = 3
If
b^2 - 4ac > 0, then the roots are real.
If
b^2 - 4ac < 0 then the roots are imaginary
<span>In
this problem b^2 - 4ac > 0 3 > 0 </span>
then
the two roots must be real
