Answer:
<h2>
V ≈ 160.85 cm³ ≈ 0,161 l</h2>
Step-by-step explanation:
Volume of cylinder: V = π×r² × h
r = 3.2 cm
h = 5 cm
Volume:
V = π×(3.2)²×5 = 51.2π cm³ = 160.8495.... cm³ ≈ 160.85 cm³
Answer:
see below
Step-by-step explanation:
t> -3
There is an open circle at -3 since there is no equals sign
t is greater so the line goes to the right
Answer:
y=5x+2
Step-by-step explanation:
Slope formula:
y=mx+b
- m stands for slope
- b stands for y intercept.
Plug the information in:
y=5x+2
Answer:
Step-by-step explanation:
To put the equation into vertex form, we need to complete the square
![g(x) = (x^2 - 4x + ...) - 1\\g(x) = (x^2-4x+(\frac{4}{2})^2 ) - 1 - (\frac{4}{2})^2 \\g(x) = (x-2)^2 - 5\\](https://tex.z-dn.net/?f=g%28x%29%20%3D%20%28x%5E2%20-%204x%20%2B%20...%29%20-%201%5C%5Cg%28x%29%20%3D%20%28x%5E2-4x%2B%28%5Cfrac%7B4%7D%7B2%7D%29%5E2%20%29%20-%201%20-%20%28%5Cfrac%7B4%7D%7B2%7D%29%5E2%20%5C%5Cg%28x%29%20%3D%20%28x-2%29%5E2%20-%205%5C%5C)
This is in the form
![y = a(x-h)^2 + k\\(h, k)](https://tex.z-dn.net/?f=y%20%3D%20a%28x-h%29%5E2%20%2B%20k%5C%5C%28h%2C%20k%29)
So, the vertex is (2, -5)
and ![g(x) = (x-2)^2-5](https://tex.z-dn.net/?f=g%28x%29%20%3D%20%28x-2%29%5E2-5)
