The answer is y=-1/2x+7. Hope this would help you.
Answer:
97,655
Step-by-step explanation:
5(5)^(n-1) = 78,125
5^n = 78,125
n = 7
=> S7 = 5(5^7 -1) / (5-1)
= 5/4 (78, 125 -1)
= 5/4 (78 124) = 97,655
Answer:
Therefore the correct option is A. 7^11/4^11

Step-by-step explanation:
Given:

Solution:
We know the Identity For Law of Indices

So here we have,
x = 7
y = 4
a = 11 , then

Therefore the correct option is A. 7^11/4^11

Regular shape with six sides: That is a Hexagon
Sum of angles in a regular Polygon is: (n - 2)*180
Where n = Number of sides
For Hexagon, n = 6.
Sum = (n - 2)*180
= (6 - 2)*180 = 4 * 180 = 720°
