Answer:
13
Step-by-step explanation:
The distance between the points is the magnitude of their difference.
|(-2-3i) -(3+9i)| = |-5 -12i| = √(5² +12²) = 13
The distance between the point is 13 units.

Answer: The answer that is false is “Initially, Cassie has $20 dollars in her account.”
Step-by-step explanation: The reason why this is false is because the first statement that the slope of the line is -20 is true. The formula for slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. Next the initial value is 275 because in these problems the y-intercept is technically the starting value in these problems. So since the initial value is 275 the last statement is false.
Have a nice day!

Answer:
The correct answer is 3πcm
Step-by-step explanation:
The length of an arc is calculated using the formula P=∅/360×2πr
where ∅is the angle the arc subtends at the center of the circle, and r is the radius of the circle of which the arc is part.
2r gives the diameter which from the diagram corresponds to AB=36 cm
therefore P=30/360×π×36
=3πcm
