Equation of the circle:
Step-by-step explanation:
The equation of a circle is given by
where
are the coordinates of the center of the circle
r is the radius of the circle
For the circle in this problem, we know that:
(5,4) are the coordinates of the center
We also know that the circle passes through the point (-3,2), therefore we can calculate the radius as the distance between the point on the circle and the center of the circle:
Therefore, the equation of the circle is:

Step-by-step explanation:
sin θ=3/8
θ=sin ^{-1}(3/8)
≈22.02 °
Answer:
1) 250 meters= 0.25 km
2) 12 meters= 0.012km
3) 1 meter= 0.001 km
The constant of proportionality is 1000 meters in 1km (1000 meters)
I think there’s a mistake on the second part because 1 meter does not equal to 1000km. but I did part 1 for you!

Answer:
Step-by-step explanation:
Let, the length of the rectangle be 'L'
and, width of the rectangle be 'W'
length=2*Width+3
Area of the rectangle= 90 square feet
Area of a rectangle = Length*Width
Using Factorization Method to solve quadratic equation:
Taking common from the equation:
OR
The Width cannot be negative, therefore Width(W)=12 feet
