Answer:

14.14

Step-by-step explanation:

√(x2 - x1)² + (y2 - y1)²

√(10 - 20)² + (25 - 15)²

√(-10)² + (10)²

√(100) + (100)

√200

= 14.14

What are the approximate solutions of 4x2 + 3 = −12x to the nearest hundredth?

Gwar [14]

First
$4x^{2} + 12x + 3 = 0$
determine if this equation were factorable, it's not for this one
so I use quadratic formula, try to search the formula online

$x1 = \frac{-12 + \sqrt{(12)^{2} - 4*4*3} } {2*4} = \frac{-12 + 4\sqrt{6} }{8} = \frac{4(-3 + \sqrt{6}) }{8} = \frac{-3 + \sqrt{6}}{2} = - 0.28$
$x2 = \frac{-12 - \sqrt{(12)^{2} - 4*4*3} } {2*4} = \frac{-12 - 4\sqrt{6} }{8} = \frac{4(-3 - \sqrt{6}) }{8} = \frac{-3 - \sqrt{6}}{2} = - 2.72$

<span>x ≈ −2.72 and x ≈ −0.28 is the solution</span>

If y=2ln(x2+2)y=2ln⁡(x2+2), find the equation of the tangent line to the curve at x=4x=4.

Gwar [14]

Y=21n(x2+2)y=21n(x2+2)
21n(x2+2)(y-1)=0
n=0, x=i/2-i/2, y=1
