i know how to do the derivative part but I don't know what to do with the x=4

The rate of depreciation dV / dt of a machine is inversely proportional to the square of t + 1, where V is the value of the machine t years after it was purchased. The initial value of the machine...

The given point is (-1,3). The differential is dy/dx= -30/(4x+1)3

The question states: F(x)= int_1^x(t3+7t-6)dt ( F(x) is the integral of (t3+7t-6)dt from x to 1)

The equation is 1/(x8). The limits are x=1 and x=2. I put this into my graphing calculator and it gave me an answer of 0.142 but the answer is not right apparently. Please help!

Asap plz i tryed calculating it but its making my brain hurt i will be mad if it easy plz help lol

If f and g are differentiable and f(x)≤ g(x) on [a,b], then f'(x)≤g'(x) on [a,b]

If f and g continuous function on [a,b] then (upper: b, lower a)∫f(x)g(x)dx=[(upper: b, lower a)∫f(x)dx]*[(upper: b, lower a)∫g(x)dx].

If F(x)= (upper: x, lower: 0) ∫√(t3+1)dt then F'(2)=3
