Astudent observes that the motion of a weight oscillating up and down on a spring can be modeled by the following equation, where h is the weight's height above the ground, in meters, and t is the time, in seconds. h(t)=0.5 x sin(πt+π/2)+1 on the graph, plot the points where height, h(t), is at a maximum.

the height will be maximum at 1.5

Step-by-step explanation:

We have been given the function:

Height depends on

This will be maximum when value of its is 1

And value will be 1 when t=0.

So, substitute the value of t=0 in given function:

Hence, the height will be maximum at 1.5

step-by-step explanation:

20% of 120 is 24. if you subtract 24 from 120 you get 96

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
