A weight is attached to a spring that is oscillating up and down. It takes 6 sec. for the spring to complete one cycle, and the distance from the highest to lowest point is 7 in. What equation models the position of the weight at time t seconds?

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

found it xd it ok yt

their is no graph showing

step-by-step explanation:

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
