Answer:
![\huge\boxed{\sf d = 141\ feet}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7B%5Csf%20d%20%3D%20141%5C%20feet%7D)
Step-by-step explanation:
<u>Given Data:</u>
Circumference = C = 443 ft
<u>Required:</u>
Diameter = d = ?
<u>Formula:</u>
d = C / π
<u>Solution:</u>
d = 443 / 3.14
d = 141.0 feet
d = 141 feet

Answer:
The experimental factor that is manipulated; the variable whose effect is being studied is called <u>independent variable.</u>
Step-by-step explanation:
Consider the provided information.
In an experiment, the two principal variables are the independent and dependent variable.
An independent variable is the variable that is altered or controlled to test the effects on the dependent variable in a scientific experiment.
The variable which is tested and measured in a scientific experiment is a dependent variable.
From the above definition: The experimental factor that changed or controlled in a scientific experiment is called independent variable.
Therefore, the complete statement is: The experimental factor that is manipulated; the variable whose effect is being studied is called <u>independent variable.</u>
Answer:
y=-0.215x^2+35
Step by Step:
Let,
,
,
, ![y=21](https://tex.z-dn.net/?f=y%3D21)
We know that, the general equation of the parabola.
![y-k = a(x-h)^2](https://tex.z-dn.net/?f=y-k%20%3D%20a%28x-h%29%5E2)
![\Rightarrow y=a(x-h)^2+k .........(i)](https://tex.z-dn.net/?f=%5CRightarrow%20y%3Da%28x-h%29%5E2%2Bk%20%20.........%28i%29)
Substitute the value of
in equation
and find the value of ![a.](https://tex.z-dn.net/?f=a.)
![21=a(8-0)^2+35](https://tex.z-dn.net/?f=21%3Da%288-0%29%5E2%2B35)
![\Rightarrow 21=a\times 8^2+35](https://tex.z-dn.net/?f=%5CRightarrow%2021%3Da%5Ctimes%208%5E2%2B35)
![\Rightarrow 21=64a+35](https://tex.z-dn.net/?f=%5CRightarrow%2021%3D64a%2B35)
![\Rightarrow 64a=21-35](https://tex.z-dn.net/?f=%5CRightarrow%2064a%3D21-35)
![\Rightarrow 64a=-14](https://tex.z-dn.net/?f=%5CRightarrow%2064a%3D-14)
![\Rightarrow a=\frac{-14}{65}](https://tex.z-dn.net/?f=%5CRightarrow%20a%3D%5Cfrac%7B-14%7D%7B65%7D)
![\Rightarrow a=-0.215](https://tex.z-dn.net/?f=%5CRightarrow%20a%3D-0.215)
Hence, the equation of the parabola is:
![y=-0.215x^2+35](https://tex.z-dn.net/?f=y%3D-0.215x%5E2%2B35)
