Write the polynomial in standard form. (2 points) 4, -8, and 2 + 5i

Use the provided ruler to measure the segment shown. Find the scale of the drawing.

Yakvenalex [24]

Length of the segment is 1.5 cm (since the picture is small)

The scale is 1.5 : 1 or 1.5/1

I really need help with the question above! This is my second time asking. Am I right? If not please give me the correct answer

vredina [299]

Hey there! :D

Pay attention to the given angles.

We know that a circle is equal to 360 degrees.

We know two angles, and the other 2 are the same measure.

170+44= 214

Subtract that from 360, since that is what the circle equals.

360-214= 146

Divide that by two, since there are 2 equal angles left.

146/2= 73

<DOB= 73 degrees.

You were correct, so good work!

I hope this helps!

Please help me !!! i will mark brain-list for the correct answer !!!

Shtirlitz [24]

Answer:

B

Step-by-step explanation:

So remember that a quarter of a circle is 90 degrees, a half of a circle is 180 degrees, and a whole circle is 360 degrees.

Looking at the image shown, it must be half a circle, whihc is 180 degrees. The image tells us that the 1st angle is 7 degrees. Now, we must find the 2nd angle.

Heres what we know however:

angle 1 + angle 2 = 180 degrees.

How do we know this?

Well, there are only 2 angles in this 180 degrees. We know that the first one is 7 degrees.

Lets input that into our nice lil equation to get an answer:

7 degrees+angle 2 = 180 degrees

Now lets solve.

Subtract 7 on both sides, and your left with:

angle 2 = 173 degrees.

So the answer must be:

173 degrees

Hope this helps! ;)

Given sin(−θ)=1/5 and tanθ=√6/12 .

Natasha_Volkova [10]

Answer:

B). −2√6/5

Step-by-step explanation:

tan theta = sin theta/ cos theta

Multiply each side by cos theta

tan theta * cos theta = sin theta

Divide each side by tan theta

cos theta = sin theta/ tan theta

We know that the sin (- theta) = - sin theta since sin is and odd function

sin theta = - ( sin (-theta))

Putting this into the above equation,

cos theta = - ( sin (-theta)) / tan theta

cos theta = - 1/5 / (sqrt(6)/12)

Remember when dividing fractions, we use copy dot flip

cos theta = -1/5 * 12/ sqrt(6)

cos theta = -12/ (5 sqrt(6))

We cannot leave a sqrt in the denominator, so multiply the top and bottom by sqrt(6)/sqrt(6)

cos theta = -12/ (5 sqrt(6)) * sqrt(6)/sqrt(6)

cos theta = -12 sqrt(6) / 5*6

Simplify the fraction.

cos theta = -2 sqrt(60/5
