The n-th term a[n] is given by
.. a[n] = 4*(-5)^(n -1)
Then
.. a[7] = 4*(-5)^6 = 62,500
The 3rd selection is appropriate.

457 is <u>less</u><u> </u><u>than</u> 500, so it's rounded down
88,000
Hope this helps
Answer:
The equation is;
y = 1/2x + 7
Step-by-step explanation:
Here, we want to write in the slope-intercept form, the equation that goes through the two points
The general form of this is;
y = mx + b
where m is slope and b is the y-intercept
we start by calculating the slope of the line
m = (y2-y1)/(x2-x1)
m = (8-6)/(2-(-2))
m = 2/4 = 1/2
So we have ;
y = 1/2x + b
To get b, we use any of the two pints
8 = 1/2(2) + b
8 = 1 + b
b = 8-1
b = 7
10ft by 12ft = 120
12ft by 12 ft = 144
144-120 = 24 sq ft
You need 24 square feet.
