Solving problems using two step equations

the pressure on a scuba diver at sea level is 14.7 pounds per square inch (psi). the pressure increases 0.445 psi for each foot of depth. suppose the pressure on a diver is 32.5 psi. how deep is he?

How to simplify trig equations

express as a single trig ratio. tan²x - sin²x / tan²xsin²x-I am assuming that the expression is: [tan²(x) - sin²(x)]/[tan²(x)sin²(x)] We can divide each term in the numerator by tan²(x)sin²(x) to

How do you solve 2sin^2xtanx=tanx

please help me solve this questions i dont know what to do:)-Subtract both sides by tan(x): 2sin²(x)tan(x) - tan(x) = 0 Then, factor out the GCF of tan(x): tan(x)(2sin²(x) - 1) = 0 Finally, by zer

Log base 5 (log base 2 (log base 6 X))=0......solving for x, help!

Can someone tell me how I would go about solving for x.-When we have buncha logs, we start from outside to inside.And wehn converting to exponential form: log[m]a = n ----> m^n = a log[5](log[2](log[

How do you solve this geometry problem

Im supposed to find the angle of x and the angle of y. There are two intersecting lines kind of like this: X The top quadrant has x+2y between the top two lines segments, the right one has x-8y betwe

Evaluate the indefinite integral of 3-cos*pix/2 dx, from 0 to 1

... ∫ { 3 - cos (πx/2) } dx ... on [ 0, 1 ] = 3[ x ] - (2/π) [ sin (πx/2) ] = 3[ (1) - (0) ] - (2/π)[ ( sin π/2 ) - ( sin 0 ) ] = 3( 1 ) - (2/π)[ (1) - (0) ] = 3 - (2/π) .........................

Pi rational or irrational

pi rational or irrational-It is irrational because if you try to find the value of pi,it comes to be 3.141592654____________to infinite i.e it is non terminating.So,it is irrational.-Irrational Pi is

How do you evaluate this limit as n approaches infinity

(1 - (1/n^2))^n Please Show your working Thanks, James.-log y = n log (1 - 1/n^2) log y = log (1 - 1/n^2) / 1/n Use LHospitals rule until you dont get the indeterminate. (1 - 1/n^2) = (0 + 2n^-3)

Please Help, how to simplify: x^4/x^-5

Recall that: aⁿ/a^(-b) = a^(n - (-b)) = a^(n + b) You are subtracting 4 by -5, yielding adding both exponents.Therefore: x^(4)/x^(-5) = x^(4 - (-5)) = x^(4 + 5) = x^9 I hope this helps!-If this is
