f(x) = (2√2) sin(x)
what is f(45)
2!!!!!!!!!!

The graph of the function f(x) should be in your mind. The other graph is the same graph translated one unit to the left and three units down. Imagine both graphs in your head, draw both on the whiteboards and write the equation of the second graph.
√(x + 1) - 3

Find the distance between the point (-3, 5) and the line y = x/2 + 1
4.92

MC = x
AM = x + 3y
NB = 4x - 3y
AN = 8
CP = x
PB = 12
Solve for x and y.
x = 4
y = 4/3
200
xy = 9
x + y = 6
x = 3
y = 3

One day A found that her plane could fly at 5 times the speed of the wind. He flew 396 miles downwind in half an hour more than it took her to fly 132 miles upwind. What was the speed of her plane in still air and what was the speed of the wind?
wind is 66 mph and A is 330 mph

3log10(x) = log10(16) - log10(2)
x = 2

√(4x - 12) +√(4x) = 6
solve for y just kidding
solve for x
x = 4

If f(x) = x + 2 and g(x) = x2 + 3, find:
A. (f + g)(6)
B. (f - g)(9)
C. (f/g)(7)
A. 47
B. -72 just kidding, it is 73
C. 9/52

Sketch the graph of the function f(x) = (1/2)x-3
emmm.....ask Mr.Butterfield
300
Graph y = x2 - 4x + 2
Mr.Butterfield will answer this question
400
1/3x - 1/4y = 2
0.4y + 0.2z = 2
1/6x + 1/2z = 5/2
x = 9
y = 4
z = 2
400
(2x - 5) / (x - 6) - (x + 4)/(x + 5) = (3x + 7)/(x2 - x - 30)
x = -2 ± 2√3
400
Graph y = √x
Mr.Butterfiled knows the answer!

The following data came from an experiment performed to determine if there is a relationship between the number of years of education (e) which a person completes and the average yearly income (i) of that person. DO NOT use a graphic calculator to find the equation of the line which best fits this data and gives the average yearly income as a function of the numbers of years of education( i = me + b). Also, find the correlation coefficient for this social science data and discuss whether or not the line is a good model for the data. Also, of course you can use a graphic calculator : )
e 12 15 16 16 18 20 22
i 32 40 52 46 55 85 62

who is the smartest MIT student in your class?
BE CAREFUL!!!!!!!!!!
What is MARY!

Evaluate: (√6) sin(30) + 1/(√2) tan(60)
NO CALCULATOR!!!!!!!!!!!
√6

sin(-135) + (3√2) cos(180)
- (7√2)/2

draw: y = -5 - 20 cos(x)
please just ask Mr.Butterfield
500
use COS
y=2 cos(4/3(x−3π/8))
π is pi
