2. for a short time after a wave is created by wind, the height of the wave can be modeled using y = a sin 2pi t/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 high?
(show work)

Step-by-step explanation:

Q1

7x people=14x^2/15

1 person= (14x^2/15)÷7x

// =(7x^2/15)÷x

Each person will recieve= (7x^2/15)÷x

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.

step-by-step explanation:

i googled it and this is what i got i don't know how it is. sorry.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
