3x^2+xy-12x-4y  rearrange slightly...

3x^2-12x+xy-4y  now factor 1st and 2nd pair of terms...

3x(x-4)+y(x-4)  which is equal to

(3x+y)(x-4)

The quadratic function f(x) has real coefficients. Given that f(3 - 2i) = 0, what must be the
pishuonlain [190]

Answer:

Option (C)

Step-by-step explanation:

Conjugate root theorem:

If (a - bi) is a root of a polynomial with real coefficients, then (a + bi) will be the other root.

By this theorem, if (3 - 2i) is one root of the quadratic function 'f', other root will be (3 + 2i).

Therefore, x = (3 + 2i) will be the other root.

Option (C) will be the answer.

tigry1 [53]
It's easy, just convert all the number to the same decimal or number. Start off by converting all the numbers to decimals. 1/2 would be .50. 3/5 would be .60. By knowing this you can easily order the numbers from least to greatest. .48, .50, and .60. The answer would be  .48

Find the length of the chord of a circle of radius 100 feet subtended by an angle of 75◦ ?
miskamm [114]
1. By definition, the chord of a circle is a segment that joins the two points of an arch and if it passes through the center of the circle, is called "diameter". There is a formula that you can use to find the chord lenght. This is:

 Chord lenght=2rSin(A/2)

 2. Let's convert the angle from degrees to radians:

 75°π/180°=5π/12

 3. So, you have:

 r: It is the radius of the circle (r=100 feet).
 Sin: It is the sine function.
 A: It is the angle subtended at the center by the chord (A=5π/12).
 

 4. When you substitute these values into the formula (Chord lenght=2rSin(A/2)), you obtain the chord lenght:

 Chord lenght=2rSin(A/2)
 Chord lenght=2(200 feet)(Sin(5π/12/2))

 5. Therefore lenght of the chord is:
 Chord lenght=18.2706 feet
