- Use a linear approximation to estimate the cosine of an angle of 66°Round your answer to four decimal places. Hint: remember that 66°= π/3 and hence 6°= π/30You can check the accuracy of this approximation by noting that cos 66°≈0.4067What would be the values of the kilometer per hour, and the degree off course for this prompt?Find a cofunction with the same value as cot(3π/7).
- A 26-foot long escalator is intended to carry people a height of 11 feet. During construction, at what angle should the escalator be tilted to ensure that it reaches the correct height? Round your answer to 22 decimal places.Calculate all of the angle and arc measures needed to complete the table below.Please solve subparts D,E,F with step thank u. Im needed in 30 minutes thank u 4. A GPS receiver product is a device used to receive signalsin the form of a sine wave emitted by GPS satellites. Company A produces 70% of GPS receiver products sold in the market, company B produces 20% and company Cproduce 10%. The GPS receivers manufactured by companies A, B and C have aproduction defects are x%, y% and z%, respectively. D. Calculate z with the following formula: z = (x + y)/3 and z has an accuracy of up to one digitdecimal A B C Defective No Devective z = E. Calculate the probability of randomly selecting a GPS receiver product and gettingdefective product F. A GPS receiver is selected at random and tested. If the test results show that GPSthe receiver is defective, calculate the probability that the device was manufactured byCompany B. INFO =NM/NIM which is 43406
