Medium to Line AC

Altitude to Line AC

Bisector of Angle B

Perpendicular bisector of Line AC

Step-by-step explanation:

We can tell that the Medium here is from line AC to angle B. The line is connecting the angle to the middle of the line, making it the medium and altitude. It is also a bisector of angle B because it is directly in the middle of that angle. It is a perpendicular bisector to line AC because it forms a 90 degree angle on the bottom.

PEMDAS

Answer:

= 5² = 25

= 36 ÷ 6 = 6

= 6 × 3 = 18

= 18 + 25 = 43

Step-by-step explanation:

The order of operations is PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction From Left to Right.

First is Exponents.

5² = 5×5 = 25

From left to right, division comes first.

36 ÷ 6 = 6

Then multiplication.

6 × 3 = 18

Lastly, addition.

18 + 25 = 43

If cos -105º = -0.26 and csc -105º = -1.03, then cos 105º = ? and csc 105º = ?

Answers

Answer:

[tex]\cos(105^\circ)\approx-0.26\text{ and } \csc(105^\circ)\approx1.03[/tex]

Step-by-step explanation:

We are given that:

[tex]\cos(-105^\circ)\approx-0.26\text{ and } \csc(-105^\circ)\approx-1.03[/tex]

And we want to find:

[tex]\cos(105^\circ)\text{ and } \csc(105^\circ)[/tex]

Part A)

Remember that cosine (and secant) is an even function. By definition, this means that:

[tex]\cos(\theta^\circ)=\cos(-\theta^\circ)[/tex]

Therefore, since we know that cos(-105°) is about -0.26, it follows from the definition that:

[tex]\cos(-105^\circ)=\cos(105^\circ)\approx-0.26[/tex]

Part B)

Remember that cosecant (and sine) is an odd function. By definition, this means that:

[tex]\csc(-\theta^\circ)=-\csc(\theta^\circ)[/tex]

We know that csc(-105°) is about -1.03.

By the above definition, we can rewrite csc(105°) as csc(-(-105°)) or -csc(-105°).

Hence, it follows that:

[tex]\csc(105^\circ)=-\csc(-105^\circ)=-(-1.03)=1.03[/tex]

What is King trying to say about laws when people tell him social advocates need to create change while following the laws and not being "criminals"?"Let me give another explanation. A law is unjust if it is inflicted on a minority that, as a result of being denied the right to vote, had no part in enacting or devising the law. Who can say that the legislature of Alabama which set up that states segregation laws was democratically elected? Throughout Alabama all sorts of devious methods are used to prevent Negroes from becoming registered voters, and there are some counties in which, even though Negroes constitute a majority of the population, not a single Negro is registered. Can any law enacted under such circumstances be considered democratically structured? "Sometimes a law is just on its face and unjust in its application. For instance, I have been arrested on a charge of parading without a permit. Now, there is nothing wrong in having an ordinance which requires a permit for a parade. But such an ordinance becomes unjust when it is used to maintain segregation and to deny citizens the First-Amendment privilege of peaceful assembly and protest. I submit that an individual who breaks a law that conscience tells him is unjust, and who willingly accepts the penalty of imprisonment in order to arouse the conscience of the community over its injustice, is in reality expressing the highest respect for law."
