Answer:
The length of the missing side x = 47.57 in
Step-by-step explanation:
Given
Ф = 28°
The length of the side adjacent to the angle Ф is = 42 in
To determine
The hypotenuse x = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
substitute adjacent = 42 in, hypotenuse = x and Ф = 28°
cos 28° = 42 / x
x = 42 / cos 28°
x = 47.57 in
Therefore, the length of the missing side x = 47.57 in

Answer:
h'(1)=0
Step-by-step explanation:
We use the definition of the derivative of a quotient:
If
, then:

Since in our case we want the derivative of
at the point x = 1, which is indicated by: h'(1), we need to evaluate the previous expression at x = 1, that is:

which, by replacing with the given numerical values:

becomes:

Formula for area of a rectangle is the base x height.
