Three ballet dancers are positioned on stage. Jada is 2 meters straight behind Trisha and 4 meters directly left of Ken. When the music begins, Jada twirls to Ken's position, then leaps to Trisha's position, and finally walks back to her original position. How far did Jada travel? If necessary, round to the nearest tenth.

10.5 meters

Step-by-step explanation:

in their starting position all three dancers form a right triangle with legs equal to 2m and 4m.

Jada to Ken = 4m

From Ken's position to Trisha's, Jada goes another 2m*

From Trisha's position to her original position, Jada goes another 2m

* to get this value: 2² + 4² = x²

x² = √20 = 2√5

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
