Answer:
S = 8
Step-by-step explanation:
An infinite geometric series is defined as limit of partial sum of geometric sequences. Therefore, to find the infinite sum, we have to find the partial sum first then input limit approaches infinity.
However, fortunately, the infinite geometric series has already set up for you. It’s got the formula for itself which is:

We can also write in summation notation rather S-term as:

Keep in mind that these only work for when |r| < 1 or else it will diverge.
Also, how fortunately, the given summation fits the formula pattern so we do not have to do anything but simply apply the formula in.

Therefore, the sum will converge to 8.

Answer:
<em>(-3, -129)</em>
<em></em>
Step-by-step explanation:
Given
Two lines:


are perpendicular to each other and intersect at point (-8,3).
To find: (P, Q)
Solution:
The two lines intersect at (-8,3).
It means, the equation of line will be satisfied when we put value of x = -8 and y = 3
Putting in the second equation, we will get an equation in P and Q:

Given that two lines are perpendicular.
It means the product of their slopes will be equal to -1.
i.e. 
Slope of a line of the form
is given as:

So, slopes of given lines are:

Using the condition:

Putting the value of P in equation (1):

So, answer is <em>(-3, -129)</em>
Answer:
B. x < 24
Step-by-step explanation:
16 > - 8 + x
+8 > +8 + x Add 8 to both sides
24 > x
Final answer: x < 24
