Find the exact value of sin 240

Given That Sin 60 = Root3/2Find The Exact Value Of Sin 240

Answers

Answer 1

Answer:

[tex]sin 240^\circ = - \dfrac{\sqrt{3}}{2}[/tex]

Step-by-step explanation:

We are given that:

[tex]sin 60^\circ = \dfrac{\sqrt{3}}{2}[/tex]

We need to find

[tex]sin 240^\circ = ?[/tex]

240 is greater than 180 and lesser than 270

OR

[tex]180^\circ<240^\circ<270^\circ[/tex]

So, Angle [tex]240 ^\circ[/tex] lies in the 3rd quadrant and it is well known that value of sine in 3rd quadrant is negative.

Using the property :

[tex]sin(\pi + \theta) = -sin\theta[/tex] or

[tex]sin(180^\circ + \theta) = -sin\theta[/tex]

Here, [tex]\theta\ is\ 60^\circ[/tex].

[tex]sin 240^\circ =sin(180^\circ + 60^\circ) = -sin60^\circ\\\Rightarrow -\dfrac{\sqrt{3}}{2}[/tex]

Hence, the value

[tex]sin 240^\circ = - \dfrac{\sqrt{3}}{2}[/tex]

At which values of x does the function F(x) have a vertical asymptote? Check
all that apply.
7
2*x+3)(x - 9)

Answers

Answer:

B, C and F

Step-by-step explanation:

Given

f(x) = [tex]\frac{7}{2x(x+3)(x-9)}[/tex]

The denominator of f(x) cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the values that x cannot be and if the numerator is non zero for these values then they are vertical asymptotes.

solve

2x(x + 3)(x - 9) = 0

Equate each factor to zero and solve for x

2x = 0 ⇒ x = 0 → C

x + 3 = 0 ⇒ x = - 3 → B

x - 9 = 0 ⇒ x = 9 → F

Answer: 9, 0, -3

in the following triangle theta=60.Find the values of the angles of the angles B and B'

Answers

Answer:

180-60 = 120 if triangle is not equilateral it cannot be isosceles then depending where the angles are they will show  60,60,60 if equilateral

For isosceles it would need to be 58 61 61 as 60, 60,60 cannot be isosceles.

3. Solve the following equation for

-x - 5y = -29 + 4y - y +5​

Answers

Im pretty sure its 2 but not exactly

Answer:

Step-by-step explanation:

-x - 5y = -29 + 4y - y + 5

Add x to both sides

-x - 5y + x = -29 + 4y - y + 5 + x

-5y = 4y - y  -29 +5 + x  {Add the like terms}

-5y = 3y - 24 + x  {subtract 3y form both sides}

-5y - 8y = 3y - 24 + x - 3y

-13y = x - 24

Divide both sides by (-13)

y = (x-24)/-13

y = -(x-24)/13

B)

C)

D)
48




Answers

Answer:

1) B

2) A

Step-by-step explanation:

1) When a triangle is similar it means that all the angle measures are the same.

So for triangle UVT the angle measures are:

U=29.95, V=56.25, T=93.82

For triangle RSQ the angle measures are:

R=29.95, S=56.25, Q=93.82

So the answer is that they are similar (triangle UTV ~triangle RQS)

2) For this problem each sided is proportional because of the parallel lines. (It's been a while since I've done this kind of math but I'll give it a go)

30/25=x/35

25x=30(35)

[tex]KQ = PN[/tex]

We can't state that because we don't know if ∠NPK is 90º

Triangle KPN is similar to triangle KQN

It is the same case as the alternative a, we can't say the triangles are similar because we don't the angles for KPN. We know that LN is perpendicular to NP, but we don't if NP is perpendicular to PK, ∠NPK might be 89,9º, that is almost 90º.

KP = 0.5 LN

Once the four sides of the square are equal, LQ = QN. But from the picture we can only state that KP length is approximately the length of NQ (or 0.5 LN)

PN || KM

That's the correct answer! Once ∠QNP is 90º, PN is perpendicular to KM.

Ariel is working at a meat- packing plant 5 nights a week. Her regular wage is $11 an hour. She earns time and a half for any overtime hours. This week she worked 9 hours of overtime. How much will Ariel earn for overtime this week?

Answers

Answer:

She will earn $148.50 in overtime this week.

Step-by-step explanation:

First, you multiply 11 by 1.5. That gets you 16.5. So, for every overtime hour she works, she gets $16.50. Since she works 9 overtime hours, you multiply 16.5 by 9 to 148.5. So, she earns $148.50 for overtime this week.

Sullivan and Carter both went trick or treating in the neighborhood, and now they're

what does that tell you about the relationship between the amount of candy they
each had?

Answers

Answer:

Step-by-step explanation:

Carter got twice number of candies in comparison to Sullivan or Sullivan got half number of candies compare to Carter.

What is amount?

" Amount is defined as the representation of total quantity of given object."

According to the question,

Number of candies Sullivan got = s

Number of candies Carter got = 2s

 Compare the given amount of data we get,

Number of candies Carter got = 2(Number of candies Sullivan got )

This shows Carter got twice number of candies comparison to Sullivan.

or

Number of candies Sullivan got = [tex]\frac{1}{2}[/tex] (Number of candies Carter got)

Sullivan got half number of candies compare to Carter.

Hence, we conclude Carter got twice number of candies in comparison to Sullivan or Sullivan got half number of candies compare to Carter.

SUBMIT ANSWER

Answers

Answer:

When using the given information, the diameter of the circle is going to be 28 mL.

Step-by-step explanation:

First, we need to know the formula for finding the area of a circle.

[tex]Area=r^2\pi[/tex]

Now, we need to rearrange the formula so we can find the radius.

[tex]Radius=\sqrt{\frac{A}{\pi} }[/tex]

Next, we plug in the given area into the equation.

[tex]Radius=\sqrt{\frac{615}{\pi}}[/tex]

[tex]Radius=\sqrt{196}[/tex]

[tex]Radius=14[/tex]

Now that we have the radius, we can find the diameter. The radius is half the length of the diameter. So, in order to find the diameter, we have to multiply the radius by 2.

[tex]14 * 2=28[/tex]

So, the diameter of the circle is 28 mL
