Trigonometry

sin(-1sin(1.325))

sine of the inverse sine of 1.325

+ more- less
Asked by Babra from Stillwater, MN

Carlos's Answer:

Wrong answer.  Sine and inverse sine are  "inverse" functions so they cancel each other...

 

  The answer (either radians or degrees)   is   1.325

Sorry for the correction,   Carlos

Algebra Equations

Will you help me Algebra word problem?

Brianna has three times as much money as Julia. Julia has $12 more than Joseph. Together they have $113. Write an equation and solve. How much money does Brianna have? (only use one variable)

+ more- less
Asked by Chris from Kannapolis, NC
00

Carlos's Answer:

We really want to get Briana's amount  so call it B

Julia has B/3   and Joseph has   B/3  -12

 

So alltogether they have 113 = B + B/3 + (B/3  - 12)

Breaking the parenthesis and arranging the equation we get  B =  $ 75

Equations

solve -9 x+8<35 and -(1/4)x+2>=10

trying to solve these two problems

+ more- less
Asked by Asha from New York, NY

Carlos's Answer:

I submit that these are NOT two problems, but one system of inequalities.

 

 So the solution is   -3 < x < 32
