Let R be the triangular region in the first quadrant with vertices at points (0,0), (a,0), and (0,b), where a and b are positive
Salsk061 [2.6K]

Answer:

volume of the solid generated when region R is revolved about the x-axis is π ₀∫^a ( \frac{-b}{a}x + b )² dx

Step-by-step explanation:

Given the data in the question and as illustrated in the image below;

R is in the region first quadrant with vertices; 0(0,0), A(a,0) and B(0,b)

from the image;

the equation of AB will be;

y-b / b-0 = x-0 / 0-a

(y-b)(0-a) = (b-0)(x-0)

0 - ay -0 + ba = bx - 0 - 0 + 0

-ay + ba = bx  

ay = -bx + ba

divide through by a

y = \frac{-b}{a}x + ba/a

y = \frac{-b}{a}x + b

so R is bounded by  y = \frac{-b}{a}x + b and y =0, 0 ≤ x ≤ a

The volume of the solid revolving R about x axis is;

dv = Area × thickness

= π( Radius)² dx

= π ( \frac{-b}{a}x + b )² dx

V = π ₀∫^a ( \frac{-b}{a}x + b )² dx

Therefore,  volume of the solid generated when region R is revolved about the x-axis is π ₀∫^a ( \frac{-b}{a}x + b )² dx

3 litres of water is how many cups? 3 litres of water is how many cups? 1 following 5 answers 5 Report Abuse Are you sure you wa
Valentin [98]
If a cup is a regular sized cup that is 2 deciliters, and 1 liter equals 10 deciliters, that means that 1 liter = 5 cups, which means that 3 liters = 15 cups. If it is a cup that has 0.33 dl, then the correct number would be 9 cups.

The sum of 237 and six times the opposite of a number is 405. What is the number?
Bond [772]

Answer:

(A) x=-28

Step-by-step explanation:

237 -6x = 405           [note that 6*(-x) is (-6x)]

  -6x = 168           [subtract 237 from both sides]

   x = -28             [divide both sides by (-6)]

How do i draw a decimal for example 0.26?
elixir [45]
First, you need convert the decimals into fraction

0.26 = 26/100 = 13/50

The next step would be drawing 50 small boxes on a piece of paper. Make it colorless.

The final stap would be giving 13 out of those 50 boxes with different color (such as black), and you're done
