Well, let's see.secant = 1/cosinecosecant = 1/sine5/cosine + 3/sine = 0Multiply both sides of the equation by sine :5 sin/cos + 3 = 0But sin/cos = tangent .5 tan(x) + 3 = 05 tan(x) = -3tan(x) = -0.6'x' is the angle whose tangent is -0.6 .
explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?
C divided by5 then multiplied by 9 then add 32-30 divided by 5 x 9 +32=-22
There is no one solution to this problem. For example: y = x2 y = 5x y = x + 20 y = 2x / 5 + 23 These are just four of the infinite set functions that would give "y" a value of 25 when x = 5.
When you have decimals you times them buy 100 to get the percent so .5 equals 50% and .05 equals 5% and .005 equals .5%
5/8 = tan(x) x = tan-1(5/8) = tan-1(0.625) = 0.558599 + k*pi radians or 32.00538 + k*180 degrees where k is an integer
tanx = 5x = tan-1(5) = arctan5x ~ 78.69
tan(23) = 1.58815308
tan(58.5) = 1.63185 (rounded)
The tangent of 4 degrees would be equal to x/200, where x is the altitude in feet. tan(5) = x/200 tan(5)*200 = x x is about 17.4977, so, if you started at 0 feet, your altitude would be about 17.4977 feet.
6 x tan(5).
41 degrees Fahrenheit equals 5 degrees Celsius.
Every minute on a clock equals 6 degrees. 145 degrees would be pretty close to 5:01
The tangent of 37.5 degrees is 0.76732698797. The angle 37.5 degrees is 5 pi/24 radians.
Minus 5 degrees Celsius is equal to 23 degrees Fahrenheit.
23 degrees Fahrenheit = -5 degrees Celsius.
-15 degrees Fahrenheit -15 degrees Celsius
