Answer: Option A

$x=\frac{3+i}{2}$ or $x=\frac{3-i}{2}$

Step-by-step explanation:

Use the quadratic formula to find the zeros of the function.

For a function of the form

$ax ^ 2 + bx + c = 0$

The quadratic formula is:

$x=\frac{-b\±\sqrt{b^2-4ac}}{2a}$

In this case the function is:

$2x^2-6x+5=0$

$a=2\\b=-6\\c=5$

Then using the quadratic formula we have that:

$x=\frac{-(-6)\±\sqrt{(-6)^2-4(2)(5)}}{2(2)}$

$x=\frac{6\±\sqrt{36-40}}{4}$

$x=\frac{6\±\sqrt{-4}}{4}$

Remember that $\sqrt{-1}=i$

$x=\frac{6\±\sqrt{4}*\sqrt{-1}}{4}$

$x=\frac{6\±\sqrt{4}i}{4}$

$x=\frac{6\±2i}{4}$

$x=\frac{3\±i}{2}$

$x=\frac{3+i}{2}$ or $x=\frac{3-i}{2}$

What is an equation of the line passing between(4, -6) and (12, -8)?*

I am Lyosha [343]

Answer:

y= -1/4x - 5

Step-by-step explanation:

first you need to find the slope.

to do this you can use the equation: change in y/change in x which is also y2 - y1/x2-x1

-8 - (-6)/12-4

-2/8

-1/4 = slope

since the line's equation is y = mx + b, we still need to find the y-intercept. we can do this by just plugging in one of the points

-6 = -1/4(4) + b

-6 = -1 + b

-5 = b

so the final equation is y= -1/4x - 5

a colleague needs to move a 500 pound object that's on a lever. the fulcrum is 6 inches from the object. If your colleague weigh

Dafna11 [192]

Answer:

Step-by-step explanation:

The easier way to figure this is by using the concept of torque in physics. If the torque of the man is greater than that experienced by the box, the lever will tilt in the man's favor (in other words, he will move down and the box will be lifted). Torque is found by multiplying the perpendicular force by the length of the lever arm. Because we want the man's torque to be greater than the box's torque, the inequality is:

$\tau_{man}>\tau_{box}$ and

$180r>500(.1524)$ That decimal is 6 inches in terms of meters.

180r > 76.2 so

r > .42 meters or `16.67 inches. The man has to sit at a distance greater than 16.67 inches in order for the box to be lifted by the lever.
