Answer: A

Step-by-step explanation:

3x² - 10x + 5 = 0

a = 3      b = -10     c = 5

Δ = b²- 4ac = 100 - 4.3.5 = 40 > 0 => have 2 solutions

=> x = \frac{10+\sqrt{40} }{6} or x = \frac{10-\sqrt{40} }{6}

HELP ME PLEASE!<br><br> In triangle FGH, GH=1, FG=12, and GH=sq. root of 145
topjm [15]

Answer:

B&C: tan F=0.0833 & tan H=12.0000

Step-by-step explanation:

The tangent relationship is always opposite/adjacent.

When F is the reference angle, side GH (1) is the opposite side and side FG (12) is the adjacent.

1/12 is 0.0833

When H is the reference angle, FG (12) is the opposite and GH (1) is the adjacent.

12/1 is 12.

Which function below is the inverse of f(x) = x2 − 16?
bearhunter [10]
<span>f(x) = x2 − 16
y = x2 - 16
x = y2 - 16
+ 16 to both sides
x+16 = y2
divide both sides by 2
1/2x+8 = y</span>

Ac method for x^2+20x-8=0
yanalaym [24]
<h2>Explanation:</h2><h2></h2>

By using quadratic formula:

x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

\quad a=1,\:b=20,\:c=-8

x_{1,\:2}=\frac{-20\pm \sqrt{20^2-4\cdot \:1\left(-8\right)}}{2\cdot \:1}

x=\frac{-20+\sqrt{20^2-4\cdot \:1\left(-8\right)}}{2\cdot \:1}:\quad 2\left(3\sqrt{3}-5\right)

x=\frac{-20-\sqrt{20^2-4\cdot \:1\left(-8\right)}}{2\cdot \:1}:\quad -2\left(5+3\sqrt{3}\right)

So the solutions are:

\boxed{x=2\left(3\sqrt{3}-5\right),\:x=-2\left(5+3\sqrt{3}\right)}
