Answer:
Yes
Step-by-step explanation:
When you calculate it on a graph it goes to 0.
<3
That makes no sense for a question.
The answer is $542.40. To get this answer you subtract 20% from the total cost, $678. The discount is $135.60.
$678 - $135.60 = $542.40
Answer:
Because different lines meet at A forming different angles
Step-by-step explanation:
Let the unlabeled point on the diagram be E
In the attached diagram, you notice that line BA, CA, DA and EA meets at A;
These lines form different angles which are BAC, BAD, BAE, CAB, CAD, CAE, DAC, DAB, DAE, EAD, EAC, EAB
Because of the numerous angles formed at A, no angle can be referred to as <A
15. The terminal side of intercepted the unit circle at:
(0,-1).
This implies that:
This implies that:
16) We have that: .
We illustrate this on the right triangle and apply the Pythagoras Theorem as follows:
Using the mnemonics SOH-CAH-TOAH, we have:
17. We want to verify that:
Verifying from the LHS
Recall that from the Pythagorean identity:
18. We have:
When , we have
When ,
We can see this is not defined for all real values of x.
