Answer:</h2>

<h2>
Step-by-step explanation:</h2>
The graphs of
can be obtained from the graph of the cosine function using the reciprocal identity, so:

But in this problem, the graph stands for the function:

Because the period is now 4π as indicated and for
in the figure and this can be proven as follows:

Also,
as indicated in the figure and this can be proven as:

Dawson's annual premium will be $2,462.40. This can be found by going across from "Male 40-44" over to "20-year coverage" which is $13.68. Since $13.68 is per $1000 of coverage, you would multiply it by 180 to get $2,462.40.
Rachel's checks I believe would have a deduction of $63.14.
RM298
reason: multiply RM4 by 10 to get RM40 and add that to RM258 to get RM298
Answer: The total amount is $4,725.
Step-by-step explanation:
1. Based on the information given in the problem, when an employee quit before 90 days, the company loses $1,575.
2. Then, the number of employees that quit before 90 days were:
employees
3. To calculate the total amount that the company will lose if these 3 employees quit before 90 days, you must multiply 3 employees by $1,575, as following:

4. The result is $4,725.
Answer:
Part 1) 
Part 2) 
Part 3)
and 
Step-by-step explanation:
see the attached figure with letters to better understand the problem
step 1
Find the side b
we know that
In the right triangle ABC
The function sine of angle B is equal to divide the opposite side angle B (AC) by the hypotenuse (AB)

we have



substitute

solve for b


step 2
Find the side a
we know that
In the right triangle ABC
The function cosine of angle B is equal to divide the adjacent side angle B (BC) by the hypotenuse (AB)

we have



substitute

solve for a


step 3
Find the measure of angle A
we know that
In the right triangle ABC
----> is a right angle

∠A+∠B=90° ------> by complementary angles
substitute the given value
