Answer:
r = 45
A = 6361.7
Step-by-step explanation:
x^2 + y^2 = 2025
this is a circle
root 2025 will give the radius
root 2025 = 45
pi * 2025 will give the area
A = 6361.7
2x²
quadratic and monomial
- 2
I'm guessing linear since x = - 2 and y = - 2 are both lines and it's a constant
3x - 9
linear and binomial
- 3x² - 6x + 9
quadratic and trinomial
Answer:
Step-by-step explanation:
Use the formula for calculate the distance between two points:
Calculate the distance AB. Substitute the coordinates into the formula. Then:
Calculate the distance A'B'. Substitute the coordinates into the formula. Then:
As you can see, the distance A'B' is the distance AB multiplied by 1/2. Therefore, this is the scale factor.
