Answer:
tan²x + 1 = sec²x is identity
Step-by-step explanation:
* Lets explain how to find this identity
∵ sin²x + cos²x = 1 ⇒ identity
- Divide both sides by cos²x
∵ sin x ÷ cos x = tan x
∴ sin²x ÷ cos²x = tan²x
- Lets find the second term
∵ cos²x ÷ cos²x = 1
- Remember that the inverse of cos x is sec x
∵ sec x = 1/cos x
∴ sec²x = 1/cos²x
- Lets write the equation
∴ tan²x + 1 = 1/cos²x
∵ 1/cos²x = sec²x
∴ than²x + 1 = sec²x
- So we use the first identity sin²x + cos²x = 1 to prove that
tan²x + 1 = sec²x
∴ tan²x + 1 = sec²x is identity
2x^3 + 2x^2 + 5x + 1/ x^2
Answer: $28,752
Explanation:
The<u> definition of bimonthly</u> is an event that happens once in two months. 
represents "two", while 
represents "event that happens by month.
Given that Glenda receives a salary of <u>$4,792 bi-monthly</u>, we are required to find the earnings per year.
There are <u>12 months in each year</u>, and if the given value is a 2-month value, then we shall divide 12 by 2 to find that there is in total 6 of the 2-month value.
Finally, we shall <u>multiply the total number with the salary</u>, which will be $4,792 times 6.
Hope this helps!! :)
