Sin(225)

225 degrees is in the 3rd quadrant.  And in the third quadrant only tangent is positive,  sin is negative.

For third quadrant, basic angle = 225 - 180 = 45

sin225 = - sin45

sin225 = - sin45 = -0.7071

sin 225° ≈ -0.7071

Polynomial equation when zeros are -4, -2, 1, 4
jek_recluse [69]
<h2>The required poynomial equation is x^{4}+x^{3}-18x^{2}-16x+32.</h2>

Step-by-step explanation:

Given,

The zeros of the polynomial are - 4, - 2, 1 and 4

To find, the polynomial equation = ?

We know that,

The polynomial equation = (x - A)(x - B)(x - C)(x - D)

= (x + 4)(x + 2)(x - 1)(x - 4)

= [(x + 4)(x - 4)] [(x + 2)(x - 1)]

= (x^{2}-16)(x^2-x+2x-2)

=  (x^{2}-16)(x^2+x-2)

= x^{4}+x^{3}-2x^{2}-16x^{2}-16x+32

= x^{4}+x^{3}-18x^{2}-16x+32

Thus, the required poynomial equation is x^{4}+x^{3}-18x^{2}-16x+32.

zavuch27 [327]

Answer:

50.72 us fl oz

Step-by-step explanation:

Given:

500 ml of ingredient to be mixed with 1000 ml of another ingredient.

\therefore \textrm{Total solution contains} = 1500ml

Now we need to convert ml into Ounces.

Formula:

\texttrm{us fl oz} = ml \times 0.033814= 1500 \times0.033814 = 50.72 oz

\therefore \textrm{Total solution contains} = 50.72 ounces
