Use differentials to approximate the change in revenue (in dollars) corresponding to an increase in sales (or production) of one unit. Then compare this with the actual change in revenue. Function R = 90x - 0.65x² x-Value x = 60 X dollars dR = AR = dollars

The windchill index announced during the winter by the weather bureau measures how cold it "feels" for a given temperature t (in degrees Fahrenheit) and wind speed w (in miles per hour). It is calculated by the formula C(t, w) = 35.74 + 0.6215t - 35.75w 0.16 + 0.4275tw0.16 + '.+ If the temperature is 31 degrees and the wind speed is 10 miles per hour, estimate the change in the windchill temperature if the wind speed increases by 4 miles per hour and the temperature drops by 5 degrees. (Round your answer to two decimal places.)
Ex: evaluate e-t15 dt
y=absolute value of x shifted to the left by 9 units.
The value of a car decreases each year. The rate at which the value decreases is called depreciation and is a represented by a percentage. For Alina buys a car for $25,000, and the depreciation rate is 25%. That means that her car’s value goes down by 25% each year. The value can be represented by the function V(y)=25000(0.75)^v, where V represents the value of her car and y represents the number of years that she owns a car. Find the depreciated value of her car if she keeps it for 5 years. In other words, evaluate: V(5)=25000(0.75)^5, rounding to the proper decimal place for money.
Consider the function y = (1x + 1)x. (a) Differentiate y by the product rule. (b) First, multiply out the expression for y then differentiate.
