This is not the answer but 3 to the power of 3 is 27 not 9 because that 3x3 oh and amogus
Answer:
x=7
Step-by-step explanation:
6-6x=5x-9x-8
Combine like terms
6-6x=-4x-8
Add 6x to each side
6-6x+6xx = -4x-8+6x
6 = 2x-8
Add 8 to each side
6+8 = 2x-8+8
14 = 2x
Divide each side by 2
14/2 =2x/2
7 = x
Answer:
You will likely need to actually measure a few people for parts 1 and 2, but the statement in part 2 should be something like "The length of the forearm of one person will be very similar to the length of their foot" or "As the length of the forearm increases, the length of the foot will increase in similar amounts".
Since the equation in pt.3 is y = 0.860x + 3.302, if x=17, then 0.860(17) + 3.302=17.922
The next question is dependant on pt.1
The data from pt.1 should be somewhat similar to the data you collected, the values between them are different because of the allowed error margin between the two.
The data can be made into a function using the "line of best fit". The equation in part A represents a function because there are no two points where two y coordinates are on the exact same x coordinate.

Step-by-step explanation:
From the picture we find that the sphere and the cylinder has equal heights.
i.e. cylinder has height = 2r.
x,y and r form a right triangle with hypotenuse as r.
Hence pythagorean theorem is satisfied
Area of the cross section parallel to it is area of circle with radius y
= ![\pi y^2\\=\pi (r^2-x^2)\\=\pir^2-\pix^2](https://tex.z-dn.net/?f=%5Cpi%20y%5E2%5C%5C%3D%5Cpi%20%28r%5E2-x%5E2%29%5C%5C%3D%5Cpir%5E2-%5Cpix%5E2)
Volume of cylinder when 2 cones removed = ![\frac{4\pir^3}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%5Cpir%5E3%7D%7B3%7D)
Hence volume of sphere = ![\frac{4\pir^3}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%5Cpir%5E3%7D%7B3%7D)
