![x = 7y - 6](https://tex.z-dn.net/?f=x%20%3D%207y%20-%206)
![x + 6 = 7y](https://tex.z-dn.net/?f=x%20%2B%206%20%3D%207y)

We know that
[the area of a circle]=pi*r²
for r=4 ft
[the area of a circle]=pi*4²------> 50.24 ft²
if 2π radians ( full circle) has an area of-----------------> 50.24 ft²
5π/2 radians--------------------------------------> X ft ²
X=(5π/2)*50.24/2π-------> 62.8 ft²
the answer is
62.8 ft²

Step-by-step explanation:
we know that
A geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
![a_n=r^{n-1}](https://tex.z-dn.net/?f=a_n%3Dr%5E%7Bn-1%7D)
where
a_n---->
term of the sequence
r ---> is the common ratio
a ---> the first term of the sequence
![a=50\\r=100\%-10\%=90\%=90/100=0.90](https://tex.z-dn.net/?f=a%3D50%5C%5Cr%3D100%5C%25-10%5C%25%3D90%5C%25%3D90%2F100%3D0.90)
substitute
![a_n=50(0.90)^{n-1}](https://tex.z-dn.net/?f=a_n%3D50%280.90%29%5E%7Bn-1%7D)
For n=12
substitute
![a_n=50(0.90)^{12-1}=16](https://tex.z-dn.net/?f=a_n%3D50%280.90%29%5E%7B12-1%7D%3D16)
Answer:
a) True
Step-by-step explanation:
The left side is where the corner or 0 is, so if a line goes up towards the right, the answer would be positive.
Answer:
x=1
