If csc theta = -2.06, find sec(theta-pi/2)

Find the exact value
sin pi/ 18cos pi/9 + cos pi/18sin pi/ 9

Please help me soon, i dont need an explanation but it would be very helpful or if you know a website that can help me i will be very appreciative!

a) sec (θ -π/2) =  co secθ

b)

Step-by-step explanation:

a)

Given co sec θ = -2.06

sec (θ -π/2) = sec(π/2 -θ) = co secθ

b)

we will use formula

sin A cos B + Cos A sin B = sin(A+B)

Given

                                                =  

                                                =

                                                =

                                               =  

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
