What are the zeros of the quadratic function f(x) = 6x ^ 2 - 24x + 1 ?

ZanzabumX [31]

Answer:

x = $\frac{12+\sqrt{138} }{6}$ and x = $\frac{12-\sqrt{138} }{6}$

Step-by-step explanation:

Let's use the quadratic formula, which states that for a quadratic of the form ax² + bc + c, the zeroes are: $x=\frac{-b+\sqrt{b^2-4ac} }{2a}$ or $x=\frac{-b-\sqrt{b^2-4ac} }{2a}$ .

Here, a = 6, b = -24, and c = 1. Plug these in:

$x=\frac{-b+\sqrt{b^2-4ac} }{2a}$

$x=\frac{-(-24)+\sqrt{(-24)^2-4*6*1} }{2*6}=\frac{24+\sqrt{552} }{12}=\frac{24+2\sqrt{138} }{12} =\frac{12+\sqrt{138} }{6}$

AND

$x=\frac{-b-\sqrt{b^2-4ac} }{2a}$

$x=\frac{-(-24)-\sqrt{(-24)^2-4*6*1} }{2*6}=\frac{24-\sqrt{552} }{12}=\frac{24-2\sqrt{138} }{12} =\frac{12-\sqrt{138} }{6}$

Thus, the zeroes are: x = $\frac{12+\sqrt{138} }{6}$ and x = $\frac{12-\sqrt{138} }{6}$ .

Which is equivalent equation solved for h?

Delicious77 [7]

Answer:

The answer is option A.

p = 0.7(rh + b)

Making h the subject

divide both sides by 0.7

we get

p/0.7 = rh + b

send b to the left side of the equation

p / 0.7 - b = rh

divide both sides by r

we get

( p / 0.7 - b) ÷ r = h

therefore h = ( p / 0.7 - b ) ÷ r

Hope this helps

A force of magnitude F stretches a spring a distance of 2 cm from its rest position. What magnitude of force will stretch the sp

SIZIF [17.4K]

Answer:

Step-by-step explanation:

Force = k * x

so k = force/distance = F/2

if you were to duplicate the distance 2 times more, the F must also do so so that it's proportional

so F*2 = 2F but since it says additional 4cm, you will need to add the initial one and this one so that it's 6cm in total.

2F + F = 3F
