The price function for selling Squinks is p = 165 - 6x. Sales are 36 per day and dropping at 5 per day. How quickly is revenue changing?

25. The formula gives the velocity v in feet per second of an object that has fallen h feet. Find the velocity of an object that has fallen 93 feet. Round to the nearest hundredth.

Consider the space X of all polynomials in t of degree 2, that is all polynomials of the form x(t) = (a1)t^2 + (a2)t + a3 where the constants (ai) are real numbers. a.) Is the operator L such that y=Lx iff y(t)=(t+1)(dx/dt) a linear transformation? b.)Represent L as a matrix operator with...

an airplane is flying at an altitude of 7 mi and passes directly over a radar antenna as shown in the figure. when the plane is 10 mi from the antenna (s=10) the radar detects that the distance s is chnanging at the rate of 300 mph. what is the speed of the airplane at that moment

Write a linear differential equation relating motor speed (Wm) to armature voltage (Ea) by manipulating the following equations: (1) - (T)=(Kt)*(C) (2) - (Em)=(Kb)*(Wm) (3) - (Lm)*(d/dt)(C) + (Rm)*(C) + (Em) = (Ea) (4) - J*(d/dt)(Wm) + (B)(Wm) = T (hint solve for arm current (i) by...

At a party I gave, attended only by couples, some people shook hands. Upon enquiry, I discovered at the end that everyone else had shaken a different number of hands. How many hands did my spouse shake?

the length of a rectangular yar is 50 ft, and its perimeter is less than 170 ft. describe the width of the yard.

the rate of growth of a particular population is given by Dp/dt=50t^2-60t^3/2 where t is time in years. If the initial population is 25,000, how long will it take the population to double?
