Express 9^(3x + 1) in the form 3^y , giving y in the form ax + b, where a and b are constants.

9^ (3x + 1) We know that 3 to power of 2 equals 9. 3x3 = 3^2 = 9, = 3^ (2 * [3x + 1]) We simply the term because 2 * [3x + 1] = 6x + 2 = 3^ ( 6x + 2) This term is in the form of 3^ y, so we know that y = 6x ...

A tunnel has height, h, (in metres) given by h=14-x^2 where x is the horizontal distance from the centre of the tunnel. Find the cross sectional area of the tunnel. Also find the maximum height of a truck passing through the tunnel that is 4m wide.

Firstly, solve 0=14-x^2 to find the horisontal distance to the edges of the tunnel. x1=sqrt(14), x2= -sqrt(14). Integrate h=14-x^2 between x1 and x2 28*sqrt(14) -(2(sqrt(14)^3))/3. This is the required area ...
