Two rectangles are similar. one has a length of 11 cm and a width of 10 cm, and the other has a width of 7 cm. find the length of the second rectangle. round to the nearest tenth if necessary. 5.8 cm 6.4 cm 8.9 cm 7.7 cm

Step-by-step explanation:

If the rectangles are similar to one another, then their sides exist in proportion to one another.  Set up a proportion with the larger rectangle on top and the smaller rectangle on bottom:

Cross multiply to get

10x = 77 so

x = 7.7

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
