Answer:
(d) -1.83
Step-by-step explanation:
The explicit expression for the sum is ...
S = (-11/5)×(1 -(-1/5)^10)/(1 -(-1/5)) = -2.2(1 -1.024×10^-7)/1.2
S = -1.8333331456
The sum is approximately -1.83.

A calculator or spreadsheet can also find the sum for you.
Answer:
Step-by-step explanation:
Answer:C) x2 + y2 =45
Step-by-step explanation:
The equation of a circle in standard form is (x-h)2+(y-k)2=r2.
Since you know the center is (0,0), you can sub this is value in for h and k, then use the point (3,6) to sub in for x and y and you will find r2 =45. Hope that helps :)
Answer:
The solution is (-2, 4)
Step-by-step explanation:
When finding the solution of system of equations, you need to find where both lines intersect.
In the graph shown, the light purple and dark purple line meet at (-2, 4).
Hope this helps!!
A because we all know the intersection of sin is always in (0,0) but in this case it is different
