Full circle
Circumference = 2*pi * r
Circumference = pi * d
Area = pi r * r = pi * r^2
Area = pi d^2 / 4
Half circle
Circumference = pi * r
Circumference = pi * r / 2
Area = pi r^2 / 2
Area = pi d^2/8
The answer depends on what you are looking for and what you are given. But those are the only common formulas I can think of at the moment.
Answer:
y = 4x² - 16x + 16
Step-by-step explanation:
Standard form is y = ax² + bx + c
To convert from vertex form to standard form multiply out the equation
1. Solve (x-2)² using F.O.I.L.
(x - 2) · (x - 2) = x² - 4x + 4
y = 4(x² - 4x + 4)
2. Distribute the 4
y = 4x² - 16x + 16
The equation is y=2x+5 and there are two options like that so yea
Answer:
(-2, -9)
explanation:
original coordinates of B: (7, 9)
use the formula: (x, y) ---> (x, -y)
- if reflects over x-axis new coordinates: (7, -9)
If horizontally shifted there will be change in x axis,
- new coordinates (7-9,-9) → (-2, -9)
