A, B and C are collinear and B is in the middle.

so we have AB + BC =AC

6x +x-5= 23

7x -5=23

adding 5 to both sides

7x=23+5

7x =28

dividing both sides by 7

we get x=28/7 =4

So answer is x=4

A block is set in motion hanging from a spring and oscillates about its resting position
coldgirl [10]

Answer:

t = 1.277 sec and t = 2.848 sec

Step-by-step explanation:

This problem is much more easily done by graphing it than by computing it using algebra.

The values of t we're looking for are the ones that make x = 0, so we want the solutions of 0.6sin(2t)+0.4cos(2t)=0 on the interval [0, 3].

According to the graph, this is true when t = 1.277 seconds and t = 2.848 seconds.
