the answer is 10cents i think.. i used decision

Answer:10.07

Step-by-step explanation: I got my answer by dividing 24 and 2.25. First, I set up my equation, 24 / 2.25. Then, i multiply 2.25 by 10, which was 22.5. Then i subtracted, which was 1.5 then i bring down my 0. 2.25 doesnt go into 1.50 so I add a 0. then i bring down a 0.

First is Exponents.

5² = 5×5 = 25

From left to right, division comes first.

36 ÷ 6 = 6

Then multiplication.

6 × 3 = 18

Lastly, addition.

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]
