- I don't understand why w(x,t)= x+(1-x)t^2arrow_forwardIn an experiment, a solution of hydrochloric acid is to be kept between30° and 35° Celsius. What is the range of temperature in degree Fahrenheit if conversion formula is given by C = 5/9(F – 32), where C and F represent temperature indegree Celsius and degree Fahrenheit, respectively.arrow_forwardA researcher in physiology has decided that a good mathematical model for the number of impulses fired after a nerve has been stimulated is given by y=−x2+40x−50, where y is the number of responses per millisecond and x is the number of milliseconds since the nerve was stimulated. (a) When will the maximum firing rate be reached? (b) What is the maximum firing rate?arrow_forward
- If x^1/4 + y^1/4 = 2, What is y'' at (1,1)?arrow_forwardHow do I find the possible inflection points of f(x)=a/((x^2)+(b^2))? It also states a and b are parameters, and that I have to assume a,b>0.arrow_forwardIs the following statement true or false. Justify your choice. Given the equation y=(kx)/z , if z increases, then y also increases.arrow_forward
- Suppose I am in a boat and I travel at the bearingN80°E at 33 knots for 5 hours. At the end of the 5-hourtrip, how far north has the boat travelled and how fareast has the boat travelled?arrow_forwardThe length L of a metal rod is given in terms of the temperature T (°C) by L = 39.6 + 0.025T cm. Within what range of temperature must the rod be kept if its length must be maintained within ± 1 mm of 40 cm?arrow_forward
