How do you confirm that f and g are inverses by showing that f(g(x))=x and g(f(x))=x ? Problem: f(x)=3x-2 and g(x)= x+2 --- 3 Please help, don't know where to begin?

Find lim x->infinity (x^2-1)/x or state that the limit does not exist. I'm not good at all with limits.

solve sin(theta)=-1 for all real values of (theta) I don't understand but by following the example in my book; sec(theta)=-1 from the pattern of the secant function, sec(theta)=-1 if theta=pi*n, where n is an odd integer. There is no example of sin.

Use the law of cosines to solve ABC with A=126.3, b=45, and c=62.5 I did all the work to find a but my problem is finding B a=96.2 Sin(B)=45sin126.3/96.2 B=Sin^-1(45sin126.3/96.2) It's not going through in my calculator

A surveyor sets a stake and then walks 150 ft north, where she sets a second stake. She then walks 300 ft east and sets a third stake. How far from the first stake is the third stake? Round to the nearest tenth. All I know is you use law of sines and subt...

If 0<theta<90 and tan theta= (square root 3)/2, find cos theta? tan(t) =ã3 /2; cos(t) = 1/ã(1+(tant)^2)= 1/ã(1+3/4) = 2/ã7 right or wrong?

If a and B are two angles in Quadrant 2 such that tan a=-1/2 and tan B= -2/3, find cos(a+b)? tan(a) = -1/2 oppsite side = 1: adjacentside = 2 hypotenuse = sqrt(1+4) = sqrt(5) sin(a) = 1/ã5 cos(a) = -2/ã5 tan(b) = -2/3 opposite side = 2 and adjacentside...

Is it cheaper to use the dishwasher or wash them by hand? I think dishwasher but I need some kind of proof. Ive read serveral times that im right but can someone confirm?

Write the standard form of the equation of the circle that passes through (0,4) and has its center at (-3, -1) (x+3)^2+(y+1)^2=sqrt34

A football is kicked with an initial velocity of 42 ft/sec at an angle of 35 degrees with the horizontal. How far has the football traveled horizontally after 0.5 sec? round to nearest tenth. Could someone explain this please?

How do you make a stem and leaf plot if one of the numbers is 100? All of my numbers are 2 digits ecept 100.

thank you for the links and everything but I need someone outside the computer world to explain

my previous post still stands but is the answer 5pi/2?

Sin(B)/45=126.3/96.2 im stuck there

B=1.03 and C=52.67

the awnser is d it very easy in word form it is people went and go fast

HELP I AM STUCK ON LESSON 80 UNIT 50 i dont know what to do the question is what is the square root of negative pi i dont know what to do

grade 6 ok guys
