Answer:
The answer to your question is 
Step-by-step explanation:
Data
cos Ф = 3/5
tan2Ф = ?
Quadrant IV
Process
1.- Remember that tanФ =
and cos Ф = 
then, adjacent side = 3 and hypotenuse = 5
2.- Calculate opposite side
O² = h² - a²
O² = 5² - 3²
O² = 25 - 9
O² = 16
O = 4
3.- Calculate the tan 2Ф
tan 2Ф = 2(
) The opposite side is negative in the fourth
quadrangle
tan 2Ф = 
G>6-3
G>3 is definitely the answer

Answer: Discounted function will be

Step-by-step explanation:
Since we have given that
Initial cost of solar energy = $9000
Average annual cost of heating a home with solar energy = $200
Rate of discount he received on the total cost = 25%
Let the number of year will be t
According to question, we need to write a discounted cost as a function of number of years.
So, our function becomes,

Hence, discounted function will be

The true statement about the inequality is that Total sales per day is greater than $250
<h3>How to write and solve inequality equation?</h3>
- Amount earned per day = 25 + 5% of x
= 25 + 0.05x
- Thursday = 4th day of the week
The inequality:
4(25 + 0.05x) > 50
100 + 0.2x > 50
100 - 50 > 0.2x
50 > 0.2x
x > 50/0.2
x > $250
