A recent study on the wave patterns in Baler, Aurora took place. High tide is at 6:00 am with a height of 13 ft. The low tide was recorded at 3 ft at
6:00 PM. The wave pattern for the day followed a sinusoidal pattern with a
period of 24 hours, starting midnight.
(a) Sketch the graph of the wave heights.
(b) Which function (y = a sin b(x-c) + d ory a cos b(x - c) + d) will you
use to model this situation?
(c) What are the values of a, b, c, and d? Hint: a is the amplitude, period
c is the phase shift, and d is the mid height?
(d) What is the equation for your graph?
(e) How high is the wave at 12 noon?​

10 points? ? +++ me asap gabriella uses the current exchange rate to write the function, h(x), where x is the number of u.s. dollars and h(x) is the number of euros, the european union currency. she checks the rate and finds that h(100) = 7.5. which statement best describes what h(100) = 75 signifies? a) gabriella averages 7.5 u.s. dollars for every 100 euros. b) gabriella averages 100 u.s. dollars for every 25 euros. c) gabriella can exchange 75 u.s. dollars for 100 euros. d) gabriella can exchange 100 u.s. dollars for 75 euros.

The formula for the volume of a right square pyramid is given below, where a is the side length of the base and h is the height.

Farmers know that driving heavy equipment on wet soil compresses the soil and injures future crops. here are data on the "penetrability" of the same type of soil at two levels of compression. penetrability is a measure of how much resistance plant roots will meet when they try to grow through the soil. compressed soil 2.85 2.66 3 2.82 2.76 2.81 2.78 3.08 2.94 2.86 3.08 2.82 2.78 2.98 3.00 2.78 2.96 2.90 3.18 3.16 intermediate soil 3.17 3.37 3.1 3.40 3.38 3.14 3.18 3.26 2.96 3.02 3.54 3.36 3.18 3.12 3.86 2.92 3.46 3.44 3.62 4.26 use the data, omitting the high outlier, to give a 95% confidence interval for the decrease in penetrability of compressed soil relative to intermediate soil. compute degrees of freedom using the conservative method. interval: to
