I hope you are looking for these answer choices as you have not posted the choices. Therefore, I have a similar question with these answer choices.
a). tan² x - 1 = sec²x
b). 4 cosxsinx = 2cos + 1 -2sinx
c). tanx cosx cscx = 1
d). 1- tanx tany = cos(x+y) ÷ cosx cosy
<span>Options B, C, D are correct because, for all them, left-hand side equals to the right-hand side for x = 0.
The option A)
</span>tan² x - 1 = sec²x<span> is not true.
since x = 0
Therefore,
The Right hand side would be:
</span>tan² x - 1 = sec²(0)<span>
= 1
The Left hand side would be:
</span> tan² x - 1 = tan² (0) - 1
= 0 - 1
= -2
Therefore,
Both sides are not equal so it's not a trigonometric identity.
The price of the truck is 4500 dollars.
But he paid it into breakdown:
=> 1500 dollars first payment
=> 350 dollars = 10 months => 350 * 10 = 3500 dollars
=> Total = 3500 + 1500 = 5000 dollars
=> 5000 - 4500 = 500 dollars additional for 10 months
=> 500 / 10 = 50 dollars per month
=> 50 * 12 = 600 dollars for 1 year
=> 600 / 4500 = 13.33% of the yearly interest.
Answer:
Pattern is you add odd numbers, as in 1, 3, 5, 7, 9, etc.
Step-by-step explanation:
11 + 3 = 14
14 + 5 = 19
19 + 7 = 26
26 + 9 = 35
hope this helps
