Plz help ASAP compute the following Riemann sums of the function p(z)= z^2 +1 on the interval 1≤z≤4
L_{5} M_{5} R_{5}
L_{25} M_{25} R_{25}
L_{100} M_{100} R_{100}

Make an educated guess of the exact area bounded by p(x)=z^2 +1 and the z-axis on the interval [1,4]
Exact Area=

Given the function f(x) = log base 4(x+8) , find the value of f^-1(2)

Find the volume of the solid whose base is the region bounded by f(x), g(x) and the x-axis on the interval [0, 1], and whose cross-sections perpendicular to the y-axis are squares. your work must show the integral, but you may use your calculator to evaluate it. give 3 decimal places for your answe

Me because i don't understand how to do it.: )
