Answer: The volume changes by 3*3/2*3 or 27/8.
Step-by-step explanation:
8.3*4 = 33.2 kg.
Hopefully that is correct
Since Yi Ting weighs 8.3 and her brother is 4 times heavier you would multiply those two numbers to get the answer.
If the graph of a line in an x y plane and its corresponding equation is given then , all the coordinates of every point on that line will satisfy the equation is a true statement.
<h3>What is the equation for a straight line ?</h3>
An equation of a straight line is given by
y = mx+c
where m is the slope and c is the intercept on y axis.
If the graph of a line in an x y plane and its corresponding equation is given then , all the coordinates of every point on that line will satisfy the equation .
Even for a scatter plot the line of the best fit is drawn and every point on the line will satisfy the equation.

Answer: b and d
Step-by-step explanation:
Since the roots are x=2 and x=6, we can write the equation as
![f(x)=a(x-2)(x-6)](https://tex.z-dn.net/?f=f%28x%29%3Da%28x-2%29%28x-6%29)
Substituting in the coordinates of the vertex,
![-4=a(4-2)(4-6)\\\\-4=-4a\\\\a=1](https://tex.z-dn.net/?f=-4%3Da%284-2%29%284-6%29%5C%5C%5C%5C-4%3D-4a%5C%5C%5C%5Ca%3D1)
So, the equation is ![f(x)=(x-2)(x-6)](https://tex.z-dn.net/?f=f%28x%29%3D%28x-2%29%28x-6%29)
On expanding, we get ![f(x)=x^2 - 8x+12](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2%20-%208x%2B12)
