Unit: Integration

From the calculation, u is represented as x⁷ and dv as e^10xdx

The formula for calculating integration by part is expressed as:

Given

Let u = f(x) and dv = g(x)dx, according to integration by part:

Comparing the general formula above to the given integral function

f(x) = x⁷ and g(x) = e^10x

Comparing this with the formula

u =  x⁷ and dv = e^10xdx

is only a line? i think so

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
