Answer:
see explanation
Step-by-step explanation:
If f(x) and g(x) are the inverses of each other, then
f(g(x)) = g(f(x)) = x
f(g(x)) = f(x - 
) = x - + = x
g(f(x)) = g(x + ) = x + - = x
Hence f(x) and g(x) are the inverse of each other
Given:
A line passes through (-5,-3) and perpendicular to 
.
To find:
The equation of the line.
Solution:
We have,
On comparing this equation with slope intercept form, i.e., 
, we get
It means, slope of this line is 
.
Product of slopes of two perpendicular lines is always -1.
Slope of required line is 
and it passes through the point (-5,-3). So, the equation of the line is
where, m is slope.
Therefore, the equation of required line is 
.
Answer:
Surface Area is 56π cm²
Step-by-step explanation:
The area for a cylinder's surface area is
a=2πrh+2πr²
The cylinder base's radius is 4 cm
The cylinder's height is 3 cm
Putting into the equation:
a=2×π×4×3+2×π×4²
a=2π×4×3+2×π×4²
a=8π×3+2×π×4²
a=24π+2×π×4²
a=24π+2×π×16
a=24π+2π×16
a=24π+32π
a=56π
The surface area of the cylinder is 56π cm².
