Since it is looking for the sum
at S3, replace n with 3 , 2, and 1 , solve the equation and add all of answers together
when s = 3 the equation becomes 5(1/3)^3-1
5(1/3)^2 = 5/9

when s = 2 the equation becomes 5(1/3)^2-1
5(1/3)^1 = 5/3

when s = 1 the equation becomes 5(1/3)^1-1
5(1/3)^0 = 5

5/9 + 5/3 + 5 = 65/9

the answer is the 3rd choice

Describe the transformation required to obtain the graph of the given function from the basic trigonometric graph.

Alik [6]

Answer:

Option d

Step-by-step explanation:

If the graph of the function $y=cf(x) +b$ represents the transformations made to the graph of $y= f(x)$ then, by definition:

If $0$ then the graph is compressed vertically by a factor c.

If $|c| > 1$ then the graph is stretched vertically by a factor c.

If $c$ then the graph is reflected on the x axis.

If $b> 0$ the graph moves vertically upwards.

If $b$ the graph moves vertically down

In this problem we have the function $y=cscx -9$ and our parent function is $y = cscx$

therefore it is true that $c =1$ and $b =-9 < 0$

Therefore the graph of $y=cscx$ is not stretched vertically and is not reflected. however as $b$ then the graph moves vertically 9 units down. Observe the image
