Find an equation of the form y = a*b^x + c*sin(pi/2 x) that fits the data below:

a= ?

b= ?

c= ?

x 0 1 2 3

y 3 18 48 186

Solve 8cos(2t) = 8cos^2(t)-2 for all solutions 0≤t<2pi

What is the minimum and maximum value of this function ?

f(x)= -5.6sin(x) + 4.7cos(x)

I have no clue how I would solve this, please help.

Solve 6sin^2(x) - cos(x) - 4 = 0, for all solutions 0 ≤ x < 2pi

Tried this multiple times and can't manage to get it :c

Please & thanks so much.

This application asked me "Degree Granted?" and I'm still a student in college, but don't have a degree yet. Would I answer "In Progress" or "Some College - No Degree" ?

Given the equation:

y=6sin((pi)/6 x+(7pi)/6)+5

Not sure if I typed that right so here's a pic: http://puu.sh/4Miou.png

The amplitude is: 6

The period is: 12

The horizontal shift is: __?__ units to the Left.

The midline is: y = 5

Outside temperature over a day can be modeled as a sinusoidal function. Suppose you know the temperature is 45 degrees at midnight and the high and low temperature during the day are 55 and 35 degrees, respectively. Assuming t is the number of hours since midnight, find an equation for the temperature, D, in terms of t ?

A radio tower is located 350 feet from a building. From a window in the building, a person determines that the angle of elevation to the top of the tower is 32 degrees and that the angle of depression to the bottom of the tower is 21 degrees. How tall is the tower?

I think I keep drawing the picture wrong which keeps messing me up.. Help please, and thank you.

Simplify and write the trigonometric expression in terms of sine and cosine:

tan(x)+cot(x) = 1/(f(x))

1/(f(x))= ?

Simplify sin(t)/(sec(t)-cos(t)) to a single trig function ?

Do I have to break down the sec ?

A truck with 32 inch diameter wheels is traveling at 50 mi/h.

- Find the angular speed of the wheels in rad/min?

- How many revolutions/min do the wheels make?

This is so confusing.. I've been on this problem for hours. Please and thank you.

A small radio transmitter broadcasts in a 51 mile radius. If you drive along a straight line from a city 64 miles north of the transmitter to a second city 70 miles east of the transmitter, during how much of the drive will you pick up a signal from the transmitter?

I draw out the picture but I just don't understand how you find the coordinates. And you use the distance formula correct ?

I'm a girl, and I was just curious about what a wider range of people can think of. Thanks !

My boyfriend and I have been in a relationship since 2010. And I mean I love him, and he's nice and caring, but sometimes the things he talks about or the way he talks to me just gets really annoying and pisses me off. Any way I can not be like that ? Or is something wrong with me ?
