Answer: x= −15/23 y+ 200/23 There you go!
so, as you can see above, the common ratio r = 1/2, now, what term is +4 anyway?
so is the 8th term, then, let's find the Sum of the first 8 terms.
![\bf S_8=512\left[ \cfrac{1-\left( \frac{1}{2} \right)^8}{1-\frac{1}{2}} \right]\implies S_8=512\left(\cfrac{1-\frac{1}{256}}{\frac{1}{2}} \right)\implies S_8=512\left(\cfrac{\frac{255}{256}}{\frac{1}{2}} \right)\\\\\\S_8=512\cdot \cfrac{255}{128}\implies S_8=1020](https://tex.z-dn.net/?f=%20%5Cbf%20S_8%3D512%5Cleft%5B%20%5Ccfrac%7B1-%5Cleft%28%20%5Cfrac%7B1%7D%7B2%7D%20%5Cright%29%5E8%7D%7B1-%5Cfrac%7B1%7D%7B2%7D%7D%20%5Cright%5D%5Cimplies%20S_8%3D512%5Cleft%28%5Ccfrac%7B1-%5Cfrac%7B1%7D%7B256%7D%7D%7B%5Cfrac%7B1%7D%7B2%7D%7D%20%20%5Cright%29%5Cimplies%20S_8%3D512%5Cleft%28%5Ccfrac%7B%5Cfrac%7B255%7D%7B256%7D%7D%7B%5Cfrac%7B1%7D%7B2%7D%7D%20%20%5Cright%29%5C%5C%5C%5C%5C%5CS_8%3D512%5Ccdot%20%5Ccfrac%7B255%7D%7B128%7D%5Cimplies%20S_8%3D1020%20)
Answer:
the root of -1 is -1
Step-by-step explanation:
When multiplied by itself, the root is typically a specified number of times gives a specified number or quantity. So -1 × -1 = -1
So there you go
Answer:
$35.31
Step-by-step explanation:
In this question, we're trying to find the total cost of the pumpkins (including tax).
We know that Carter picked a $20 pumpkin, while Isabelle picked a $13 pumpkin.
We also know that the sales tax is 7%
To get your answer, we would add the prices of the pumpkin and find the tax price to get our final answer.
Find the total cost:
20 + 13 = 33
Since the sales tax is 7%, we would multiply 33 by 1.07:
33 · 1.07 = 35.31
Mrs. Stephan paid $35.31 for the pumpkins and sales tax.
67.5 degrees
3pi/8 * 180/pi = 67.5
