So we want to find the radius of the circle. So just divide 56.52 by 3.14 and 2, which is 9. And then to find the area, just square 9 and multiply it by pi, which is 354.34 square inches.
The area of the rug is 354.34 square inches.
Answer: the number is 1
assume the number to be x. so according to the question
2 x a number is subtracted from 7 and the result is 5
the equation will be:
7-2x=5
now we have to solve for x
7-2x=5
2x=7-5
2x=2
x=1
hopefully this helped you()
Step-by-step explanation:
The correct answer is C)
![a_n=2\times(-4)^{n-1}](https://tex.z-dn.net/?f=a_n%3D2%5Ctimes%28-4%29%5E%7Bn-1%7D)
.
Since it is a geometric sequence, we multiply by a constant, r, each time to find the next term.
g₂ = -8
g₅ = 512
g₂ * r * r * r = g₅
-8(r)(r)(r) = 512
-8r³ = 512
Divide both sides by -8:
-8r³/-8 = 512/-8
r³ = -64
Take the cubed root of both sides:
∛r³ = ∛-64
r = -4
Now we work backward from g₂ to find g₁:
-8/-4 = 2
We have that g₁ = 2 and r = -4. This gives us

Answer:
Step-by-step explanation:
Assuming the decay factor, m = 0.0005
f(x) = ![1 - e^{-mx}](https://tex.z-dn.net/?f=1%20-%20e%5E%7B-mx%7D)
f(9000) =
= 1 - 0.0111 = 0.99
