You can put this solution on YOUR website! $10,637 is invested, part at 13% and the other at 6%. If the interest earned from the amount invested at 13% exceeds the interest earned from the amount invested at 6% by $880.07, How much is invested at each rate?

Factorising gives (x - 1)(x - 9) = 0 x = 1 and x = 9 give solutions to the equation. With x = 1 we have sides 5, 12 and 13 which is reasonable; but with x = 9 we have sides -3, 4 and 5 which does satisfy the equation but as we are talking about lengths (which are all positive) we disregard this answer. Therefore the sides are 5, 12 and 13 with ...

Question 42376: write 6.13 x 10^6 in standard notation. Answer by psbhowmick(878) (Show Source):

Looking at we can see that the first term is and the last term is where the coefficients are 5 and -6 respectively. Now multiply the first coefficient 5 and the last coefficient -6 to get -30. Now what two numbers multiply to -30 and add to the middle coefficient -13? Let's list all of the factors of -30: Factors of -30: 1,2,3,5,6,10,15,30

V = length × width × height V = (8-2x)(6-2x)x V = x(8-2x)(6-2x) V = (8x-2x²)(6-2x) V = 48x-16x²-12x²+4x³ V = 4x³-28x²+48x We get some points between 0 and 3: x | y ----- .2 | 8.512 .4 | 14.976 .6 | 19.584 .8 | 22.528 1.0 | 24.0 1.1 | 24.244 1.2 | 24.192 1.3 | 23.868 1.4 | 23.296 1.6 | 21.504 1.8 | 19.008 2.0 | 16.0 2.5 | 7.5 2.9 | 1.276 ...

f(x) = x^3-7x^2+25x-39 = (x-3)(x^2-4x+13) That is as far as we can factor without going into complex numbers. x^2-4x+13 has no real zeros, but it has, as expected, two conjugate complex zeros, which we can find using the quadratic formula or completing the square.

Question 231846: Two vertical poles of lengths 6 feet and 8 feet stand 10 feet apart. a cable reaches from the top of one pole to some peoint of the ground between the poles then to the top of the other pole. where should this point be located to use 18 feet of cable? could you explain how to do this for me?
