Answer:
The derivative of the function is 42.
Step-by-step explanation:
The derivative of an addition/subtraction of terms is the addition/subtraction of the derivatives of these terms.
The derivative of a constant is 0. The derivative of 3 is 0, for example.
The derivative of is
. The derivative of 42x is 42, for example.
So, in this question, we have that:
h(x) = 42x-3
h'(x) = 42
So the derivative of the function is 42.
Answer:
First Question
lower limit of 9 mph
upper limit of 9 mph
Second Question
lower limit of 120 pounds is
upper limit of 120 pounds is
Third Question
lower limit of 187 pounds is
upper limit of 187 pounds is
Step-by-step explanation:
From the question we are told that
The amount of beer administered is three 12-ounce beers
The amount of coffee administered is two cups of coffee
The speed limit is 60-mph
The smallest unit of scale is 1 mph
The first subject scores 9 mph
Generally given that the smallest unit of scale is 1 mph then the deviation of 9 mph will be by
Hence the lower limit of 9 mph is
And the upper limit of 9 mph is
Generally given that the measuring weight on a scale that is accurate to the nearest 0.2 pound then 120 pounds will deviate by
Hence the lower limit of 120 pounds is
And the upper limit of 120 pounds is
Generally given that the measuring weight on a scale that is accurate to the nearest 0.5 pound then 187 pounds will deviate by
Hence the lower limit of 120 pounds is
And the upper limit of 120 pounds is
