The theater has 175 seats. there are 7 seats in each row. how many rows are there

Use the method of cylindrical shells to find the volume v generated by rotating the region bounded by the curves about the given axis.y = 7ex, y = 7e^-x, x = 1; about the y-axis

If x+y+z=0 what is the value of [tex] {x}^{3} + {y}^{3} + {z}^{3} [/tex]

If f(x) = 4x - 3 and g(x) = x + 4, find (f - g) (x)
