x² + y² = 37
The equation of a circle centred at the origin is.
x² + y² = r² ( where r is the radius)
The radius can be calculated using the distance formula
r = √(x₂ - x₁ )² + (y₂ - y₁)²
where (x₁ , y₁) =(0,0) and (x₂ ,y₂) = (1 ,6)
r = √(1 - 0)² +(6 -0)² = √1 + 36 =√37⇒ r² = (√37)² = 37
x² + y² = 37 is the equation of the circle
Step-by-step explanation:
Area of shaded =Area of Outer rectangle - Area of Inner rectangle.
Area of inner rectangle = L× B.
L=18
B=11
Area of inner rectangle = 18×11
=198m^2
To find the full breadth of the outer rectangle
=2 in +11 + 2 in
=15
To find the full length of the outer rectangle
=2 in + 18 + 2 in
=22
Area= 22 × 15
Area = 330m^2
Area of shaded portion = 330 - 198
=132m^2
X + 3 = 2x +5
-x -5 = -x - 5
x = -2
Answer:
only non prime even numbers are square numbers ( i think)
Answer: A (y = 1)
Step-by-step explanation:
when dividing, dividing by 0 equals an undefined fraction, therefore, if y was equal to 1, it would cancel out the y - 1, making it 0. I hope that's right :0
