Sun, 06 Dec 2009 00:06:15 -0800

Q: Assuming that y is a function of x. What is y'=dy/dx for y(x)=sin(3x+4y)?

Implicit differentiation: Find dy/dx if y(x) = sin(3x + 4y) Differentiate wrt x. d/dx sin(3x + 4y) = 0 cos(3x + 4y)d/dx(3x + 4y) = 0 cos(3x + 4y)(3 + 4dy/dx) = 0 3cos(3x + 4y) + 4cos(3x + 4y)dy/dx = 0 4cos(3x + 4y)dy/dx = -3cos(3x + 4y) dy/dx = -3cos(3x + 4y) / 4cos(3x + 4y)

Answer to Verify the identity, (1+sinx)(1-sinx)=1/sec^2x

Fri, 04 Dec 2009 06:24:48 -0800

Verify the identity, (1+sinx)(1-sinx)=1/sec^2x

(1 + sinx)(1 - sinx) = 1/sec^2x Starting from LHS (left hand side) and expand the algebraic expression: 1^2 - sinx + sinx - sin^2x = 1 - sin^2x Since sin^2x + cos^2x = 1 Therefore, cos^2x = 1 - sin^2x Since cosx = 1/secx Therefore, cos^2x = 1/sec^2x

(2x+3)(3x-1) = (2x * 3x) + (2x * -1) + (3 * 3x) + (3 * -1) = 6x^2 - 2x + 9x - 3 = 6x^2 + 7x - 3

5. An increase in atmospheric pressure will cause the boiling point of the liquid to? A)Increase B)Decrease C)Remain the same D)Depends on the liquid.

Hmm ... an increase in pressure for water increases the boiling point. I think for other liquids, an increase in pressure also increases the boiling point.

The Atmosphere pressure is 100 kPa.what is the force exerted by the atmosphere on a rectangular surface thet measures 0.5m by 0.4m?

My attempt: p = F / A F = p * A F = 100,000 N/m2 * 0.5m * 0.4m = 20,000N

Fri, 27 Nov 2009 11:43:29 -0800

What is the pressure in a 1.00 liter container of methane, CH4, that contains 40.0 g of the gas at 25 degrees celsius

My attempt: By Ideal Gas Law: pV = nRT p = nRT / V Given: n = 40g / 16.0425 g/mol (molar mass) = 2.49 moles R = 8.314472 J/(mol.K) (universal gas constant) T = 273 + 25 = 298K V = 0.001m3 p = (2.49 * 8.314472 * 298) / 0.001 = 6169504.5Pa or 6.1695045 MPa

I got the same answer as yours. I don't know why and how your answer key is different. |x + 5| = |2x + 1| x + 5 = 2x + 1 x - 2x = 1 - 5 -x = -4 x = 4 or |x + 5| = |2x + 1| x + 5 = -(2x + 1) x + 5 = -2x - 1 x + 2x = -1 - 5 3x = -6 x = -2

In how many ways the letter of the word ARRANGE can be arranged?If the 2 R's does not occur together,than how many such arrangement are possible ? If besides 2 R's the 2 A's also do not occur together.How many permutations will be obtained?

My attempt: 1) Total repeating permutation of ARRANGE -> (total factorial number of permutation / total factorial number of repeating permutation) 7! / (2! * 2!) = 7 * 6 * 5 * 4 * 3 * 2 * 1 / 2 * 1 * 2 * 1 = 5040 / 4 = 1260 2) Permutation of ARRANGE with only repeating As ->...

Answer to Digit C is one more than digit A, which is twice digit D, which is 10 less than digit A plus 8. Digit B is digit A+C+D minus 2. What is the four digit number?

Fri, 27 Nov 2009 07:49:51 -0800

Digit C is one more than digit A, which is twice digit D, which is 10 less than digit A plus 8. Digit B is digit A+C+D minus 2. What is the four digit number?

I think the answer is this: C = 1 + A A = 2D D = A - 10 + 8 B = A + C + D - 2 A = 2(A - 10 + 8) = 2A - 20 + 16 = 2A - 4 A - 2A = -4 -A = -4 A = 4 C = 1 + A = 1 + 4 = 5 D = A / 2 = 4 / 2 = 2 B = A + C + D - 2 = 4 + 5 + 2 - 2 = 9 Therefore, the four...

Find an equation of the circle having the given center (0,0) that passes through the given point of (-1,3).

Given: Center of origin: (0,0) Passing through the point: (-1,3) Equation of circle centered at origin: x^2 + y^2 = r^2 The distance r = sqrt ((-1-0)^2 + (3-0)^2) r^2 = 10 Therefore, the formula of the circle is: x^2 + y^2 = 10 This is the equation of the circle with center...

I need to know the depths of 2 cylinders; a 60 litre with 420mm diameter and a 100 litre with 600mm diameter If it helps a customer measured their 142 litre with 600mm diameter and said the depth was about 550mm. Thanks Stu

The question seems to be asking for the height of the cylinders. If so then: V = Pi x r^2 x h h = V / Pi x r^2 1) Given: V = 60litre or 0.06m3 (SI unit), D = 420mm or 0.42m (SI unit) Then: h = 0.06 / Pi x (0.21)^2 = 0.43m (SI unit) or 433mm 2) Given: V = 100litre or...
