PLEASE HELP The current, I, in amperes, of an electric circuit, is given by the function I(t) 5 4.5 sin (120 pi)t, where t is the time in seconds.

a) Draw a graph that shows one cycle.

b) What is the singular period?

c) At what value of t is the current a maximum

in the first cycle?

d) When is the current a minimum in

the first cycle?

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

hi there

the slope is 1/3.

this is because from the y-intercept, you go up one, and you go to the right three, to get to the next exact point on the graph. this is known at the “rise over run.”

p.s. (if you need it).your y-intercept is -2, because that is the point on the graph where the line crosses the y-axis.

hope that : )
