For a short time after a wave is created by wind, the height of the wave can be modeled using y = a sin 2π/t, where a is the amplitude and t is the period of the wave in seconds. how many times over the first 5 seconds does the graph predict the wave to be 2 feet height?

2 times

Step-by-step explanation:

We are given that the height of the wave can be modeled using

We have to find the value of amplitude

T=5 seconds

Height =y=2 feet

Where a = Amplitude

Substitute the values then we get

Because

a=2.1

Amplitude =2 feet

Hence, the graph is 2 times over the first 5 seconds when the wave to be 2 feet height.

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
