Answer:
A(1)=4
A(n)= A(n-1)-5
Step-by-step explanation:
Plug in 1 to see that a(1)=4. Then, find a few more using the given formula and see what the change is from one to the next. It ends up subtracting 5 for every value.
Find the inside angle B of the smaller triangle using the base (4) and height (6)
smaller part of B = arctan(4/6) = 33.69 degrees
full B = 90 degrees - smaller B gives you the other part of B for the left hand side
so 90 - 33.69 = 56.31
now AD = 6 x tan(56.31) = 9 feet
answer is G
Using the mid-point concept, it is found that point B is located at coordinates (-6.5, 0).
<h3>What is the midpoint concept?</h3>
The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.
The center is the midpoint of the two coordinates of the diameter, hence:

For the x-coordinate:

x + 0.5 = -6
x = -6.5
For the y-coordinate:

y + 6 = 6
y = 0

0.714 and so does 0.224 has 4 in the thousandths place, but in shortest distance I believe it is 0.714
the line will rise more sharply than before, the slope is steeper, increased from the 2 to 2.5.
