The tides around cherokee bay range between a low of 1 foot to a high of 5 feet. the tide is at its lowest point when time, t, is 0 and completes a full cycle over a 24 hour
period. what is the amplitude, period, and midline of a function that would model this periodic phenomenon?

answer: b

step-by-step explanation:

answer:

probably the same as it is today since you did not eat the corn dogs yet

step-by-step explanation:

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
