Geometry: A circle has a diameter of 20 mm. What is the circumference of the circle?

PLS HELP ME ^^^

Solve the equation using the given values: x= -2.5; y= -7.51. 2xy + 2x²

The number of fish in a lake can be modeled by the exponential regression equation y=14.08 x 2.08^x where x represents the year

Choose the equation below that represents the line that passes through the point (2, 4) and has a slope of 3. a) y − 4 = 3(x − 2) b) y − 2 = 3(x − 4) c) y + 4 = 3(x + 2) d) y + 2 = 3(x + 4)
