Hence, the sum of a 7-term geometric series is:
-32766.
<h3><u>
Step-by-step explanation:</u></h3>
We have to find the sum of a 7-term geometric series (i.e. n=7) if the first term(a) is -6, the last term is -24,576, and the common ratio(r) is 4.
We know that the sum of the 7-term geometric series is given as:
![S_n=a\times (\dfrac{r^n-1}{r-1})](https://tex.z-dn.net/?f=S_n%3Da%5Ctimes%20%28%5Cdfrac%7Br%5En-1%7D%7Br-1%7D%29)
On putting the value of a,n and r in the given formula we have:
![S_7=(-6)\times (\dfrac{4^7-1}{4-1})\\\\\\S_7=-32766](https://tex.z-dn.net/?f=S_7%3D%28-6%29%5Ctimes%20%28%5Cdfrac%7B4%5E7-1%7D%7B4-1%7D%29%5C%5C%5C%5C%5C%5CS_7%3D-32766)
Hence, the sum of a 7-term geometric series is:
-32766.
y = (t x - m -s)/r
Step-by-step explanation:
Step 1 :
Given,
r y + s = t x - m
=> r y = t x - m -s
=> y = (t x - m -s)/r
Step 2 :
A) r can take any values except 0.
This is because when r = 0, the denominator becomes 0 and division by 0 is undefined
The limitation for r is r should not be equal to 0
The other variables can take any value. Hence the other variables do not have any limitation
Find their gradients using the change in y coords divided by the change in x coords. once you have the gradients (or slopes), multiply them by eachother - if the product is (-1) then theyre perpdendicular, if not, they are either parallel or intersect at a point
A because the 6 and 3 cancel out
Then 2 x 8 is (16) and 15 x 5 is (75)
