1 answer:

7 0

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

V=(π)(r^2)(h)

π=3
r=half of the diameter=4
h=12

V=(3)(4^2)(12)
= (3)(16)(12)
= 576 cm cubed

In a chemistry lab an experiment requires 500ml of one ingredient to be mixed with 1000 mL of another. how many ounces is the so

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:

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

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