The correct answers are:1) sin(x) =
2) tan(x) =
Explanation:Given:

Step 1:
Since, according to the Trigonometric identity:

-- (1)
Step 2:
Plug in the value of cos(x) in equation (1):

Step 3:
Take square-root on both sides:

sin(x) =

Now to find the tan(x), we would use the following formula:
tan(x) =

--- (2)
Plug in the values of sin(x) and cos(x) in equation (2):
tan(x) =

Hence tan(x) =
Answer:
The distance around the inside is 199.44 m.
Step-by-step explanation:
Given that,
Length = 84.39 m
Width = 9.76 m
Suppose, all the way around and 73 m wide.
We know that,
Perimeter of half circle is

We need to calculate the inner radius of the circle
Using formula of radius

Put the value into the formula


We need to calculate the distance around the inside
Using formula of distance
Distance around the inside= two inner perimeter of the circle+two length of rectangle

Put the value into the formula


Hence, The distance around the inside is 199.44 m.
Answer:
If asking for the distance, the answer would be C.
Given:
The height of a golf ball is represented by the equation:

To find:
The maximum height of of Anna's golf ball.
Solution:
We have,

Differentiate with respect to x.


For critical values,
.




Differentiate y' with respect to x.


Since double derivative is negative, the function is maximum at
.
Substitute
in the given equation to get the maximum height.




Therefore, the maximum height of of Anna's golf ball is 6.25 units.
