Simultaneous equations Need help again please :(

Hi again. Thanks for the help on my fractions question earlier, i didnt know how to reply sorry. Here is my next question if you could please answer and show me how you found the answer it would be ap

Does the integral converge

Does the integral∫ (x+1) / ( (x^5) + (x^2) )^1/4 , between 1 and infinity,converge or diverge?Im supposed to solve using the comparison test but I cant seem to find the right integral to compare it to

Please double check my answer for me

Here is the question: A sum of $83 was deposited in a bank on January 1 . A sum of $20 is deposited in the bank on the 12th day of each month.Suppose this pattern continues. How much will be in the b

Evaluate the definite integral please help

the integral is cost/(1+sint)dtthe limit is from 0 to pi/2 can you please explain this problem because i have a feeling it will be on my exam-∫cost(t) / 1+sin(t) dt from o to π/2 Use a u substitutio

Please solve 3x -2x^2 + 9=0

3x -2x^2+ 9=0 -2x^2 + 3x + 9 = 0 2x^2 -3x - 9 =0 2x^2-6x+3x-9=0 2x[x-3]+3[x-3]=0 (2x+3) (x-3)=0X=3, X=- 3\2 i hope it helps. gud luck fren.-3x -2x^2 + 9=0First rearrange this mess to match what you

Find the complete solution set

Didnt understand professors lecture at all. -_- Could someone explain to me in detail these 2 problems... (x^4)+4=5(x^2) log2(x) + log2(3x + 10) = 3-1)x^4 - 5x^2 + 4 = 0 (minor but critical rearrang

Help me please with this integral

integrate (sin^2 x+1)dx the limit is from -pi/2 to pi/2-sin(x)^2 + 1 => 1 - cos(x)^2 + 1 => 2 - cos(x)^2 (2 - cos(x)^2) * dx x = t/2 dx = dt / 2 Now, cos(t/2) = sqrt((1 + cos(t)) / 2) (2 - (1/2) *

Help with limits in Calculus

Let f(t) = t^3 - 4t^2 + 5t - 2 denote the position of an object (moving in a straight line) at any time t. Find values of t, if any, at which the object is stopped. And apparently this has to be done

I need help with math...

The question is Solve the Equation. Graph the solution. |y|=(-5)... from what I know, you cant have a negative absolute value?-You are right, |y| ≥ 0 therefore, there is no solution here.

The width of a rectangle is three-fourths its length. The diagonal is 10 inches. What are its dimensions? Let x be the length of the rectangle. Since the width of the rectangle is three-fourths its

Multi-Step Inequalities

Can you both solve and explain the following problems please? Easy ten points! :) 3(2x-5) ≥ 8x-5 Answer: x ≤ -10/10? :/ 7+3y > 2y-5 3(a-2) > 5a-2(3-a) I find myself struggling most with the third.

All possible combination for a 4 digit number...

I want all possible combination for a 4 digit number. But, you can only use the numbers 1,4,5,6,7,8,9,0 And the numbers 1,4 must always be in this combination(i.e you cant have 6589, since both 1 and

Integral of [ (1+cos^2(x)) / sin(x) ] dx

Indefinite Integrals-Integral of [ (1+cos^2(x)) / sin(x) ] dx We know :- sin^2(x) + cos^2(x)=1 So, cos^2(x)=1- sin^2(x) So, our integral becomes:- =Integral of ( (1 + 1 - sin^2(x))/sin(x))dx =In
