14x5=70
15x10=150
Answer- 7:15
It would be the third one
Evaluating the tangent function for the two values we obtain the following:
tan 135=tan(135+180)=tan 315=-1
next:
tan -135=tan(180-135)=tan 45=1
thus comparing the two we see that tan 135 is negative while tan -135 is positive
Answer:
I'm unsure about the first one, but the second one is irrational, the third one is option C, the fourth is option b, and the last one is D i believe
Step-by-step explanation:
Answer:
is an odd function.
Step-by-step explanation:
We are asked to prove whether is even or odd.
We know that a function is even if and a function is odd, when .
We also know that an even function is symmetric with respect to y-axis and an odd function is symmetric about the origin.
Upon looking at our attachment, we can see that is symmetric with respect to origin, therefore, is an odd function.
