Answer:
a) Y = -3x/5 + 15
b) Y = 3 - 0.6x
d) Volume = 15Pi
e) Volume of cone = 15pi
Step-by-step explanation:
The detailed steps and appropriate integration is as shown in the attached file.
Area of a rectangle is length times width, or base times height (synonymous) In your case you have length of 11ft and a width of 2inches or 2/12 ft, so your area would be 11*(2/12)ft^2 which is (22/12)ft^2, you can simplify this by dividing the numerator and denominator by 2 to give you (11/6)ft^2
To find how many times he would need to walk a dog to get 45 dollars you'll have to first create an equation
4.50x=45
simply divide both sides by 4.5
and you'll get 10 as your answer.
The Y intercept is where the function passes/ intercepts the y axis. On a table, it is where x is 0, in this case the y intercept is -20. The slope is found by change in y over change in x. So choose any two coordinates to find change. 10/5=2. So your answer is A.
The area A of a circle is equal to: pi times the radius squared
A = πr²
A = π5², which is 78.5
