Answer:

Step-by-step explanation:
using the formular for integration by parts;
∫udv = uv -∫vdu ..............equ 1
in the equation below;
∫
u=x , dv =
du= 1 v= 
Substitute into equ 1
∫udv =
- ∫
∫udv =
- 
81.27 is the answer to 21% of 387 so a good estimate would be 82
The slope of the line will be equal to 30.
Slope of a line may be defined as the steepness of a curve. Slope of line can be positive, negative or zero. Slope of a line is used to determine the equation of the line which is given as y = mx + b where m is the slope, b is y intercept and x and y are independent and dependent variables respectively. The slope of a line on points (x₁, y₁) and (x₂, y₂) is given by the formula, m = y₂ - y₁/x₂ - x₁.
According to the question the value of points is (x₁, y₁) = (0, 0) and (x₂, y₂) = (2, 60).
Now, the slope can be calculated as
m = (60 - 0)/(2 - 0)
=> m = 60/2
=> m = 30 which is the required slope.
