Solve graphically the equation x square minus x -6 is equal to zero

1 answer:

5 0

ANSWER:
If x-6=0
Then,x=6
You just need to mark 6 on the x axis and draw a line passing through it parallel to y axis.

I will mark plus 25 pts. Help please A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh

olga nikolaevna [1]

50(115-y) + 25y = 4125 [from eq2]

5750 - 50y + 25y = 4125 [distribute]

5750 - 25y = 4125

-25y = -1625

y = 65 [divide both sides by (-25)]

There are 65 small boxes.

Put that value into either equation (now, which is easier?) to solve for x:

x = 115 - y

x = 115 - 65

x = 50

There are 50 large boxes.

Express the complex number in trigonometric form. <br><br> -4i

jeka57 [31]

Answer:

-4i = 4(cos 270 +i sin 270)

Step-by-step explanation:

We have a+ib = r(cosθ+isinθ)

$r=\sqrt{a^2+b^2}\texttt{ and }tan\theta =\frac{b}{a}$

Here a = 0 and b = -4

Substituting

$r=\sqrt{0^2+(-4)^2}\\\\r=4\\\\tan\theta =\frac{-4}{0}\\\\\theta =270^0\texttt{(Since a is zero and b is negative)}$

-4i = 4(cos 270 +i sin 270)

Please help me with this math!

wel

Answer:

Please check the explanation.

Step-by-step explanation:

Given the polynomial function

$f\left(x\right)\:=x^3+2x^2-16x-32$

Let us determine the factors by solving

$\:\left0\right\:=x^3+2x^2-16x-32\:$

$\left(x+2\right)\left(x+4\right)\left(x-4\right)=0$

Using the zero factor principle:

if $ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)$

$x+2=0\quad \mathrm{or}\quad \:x+4=0\quad \mathrm{or}\quad \:x-4=0$

Thus, (x+2) (x+4) and (x-4) are the factors of the polynomial function.

Therefore,

YES

(x+2)

(x+4)

(x-4)

And (x-2) (x+6) are not the factors of the polynomial function.

Therefore,

YES

(x-2)
(x+6)
