ICE Princess25 [194]

Answer:

-1/240 (Might be wrong though)

Step-by-step explanation:

The first thing we need to do is multiply 1/15 and 1/16 because product means the answer to a multiplication equation.

1/15 times 1/16 = (1*1)/(15*16) = 1/240

Now that we know the product 1/240, we just have to find the opposite, which is -1/240 because you just add a negative sign in opposites( even in negative numbers)

I need help finding the reference angles for these angles.
Salsk061 [2.6K]
Convert the angles to degrees. Remember there are 2pi radians in a circle, and a circle has 360 degrees, so conversion factor is 180degrees/pi. Then you can easily approximate the reference angle. Remember you make the reference angle from the positive x-axis and the reference angle will be the angle between the terminal side and the nearest x-axis (either positive side or negative side of the x-axis).
1)1.4 * \frac{180degrees}{pi} = 80.214 degrees
2)-1.4 \pi * \frac{180degrees}{ \pi } = -252 degrees

Which polynomial represents the sum below?
FromTheMoon [43]

Answer:          D. 8x² + x + 3

Sum means the answer to an addition problem. To find the sum of polynomials, we will add like terms.

<h2>What are like terms?</h2>

Like terms can be combined using addition or subtraction and have the same variables. Constants are also like terms with each other because they have no variables.

<h2>Solve</h2>

(4x² + 1) + (4x² + x + 2)      Starting equation from the question

= 4x² + 1 + 4x² + x + 2       Remove brackets

= 4x² + 4x² + x + 1 + 2       Rearrange to group like terms together

= 8x² + x + 1 + 2                Add like terms with the same 'x²' variables

= 8x² + x + 3                     Add like terms that are constants
