Answer:

Step-by-step explanation:
The trigonometric identity is :

We need to express secθ in terms of tanθ.
The above equation becomes,

Hence, this is the required solution.
Answer:
The total sales of Boutique last week = $1300
Step-by-step explanation:
Given that:
Percent of sales came from leggings = 30%
Worth of leggings sold = $390
Let,
x be the total sales in the week.
30% of x = 390

0.3x = 390
Dividing both sides by 0.3

Hence,
The total sales of Boutique last week = $1300
(secx + tanx)^2

The expression (secx + tanx)2 is the same as </span>1 + 2tan2x + 2secx tanx. The answer is letter D.
Answer:
Claire's lemonade is stronger
Step-by-step explanation:
Jennie's lemonade
2/2=1
3/2=1.5
Claire's lemonade
3/3=1
4/3=1.334
Jennie's lemonade has more water in the lemonade per lemon, so Claire's is stronger.
I don't know if I used proportions though.
Hope I did this correctly!
