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>

How many times larger is the volume of a cone if the radius is multiplied by 6?

yan [13]

Answer:

36 times larger.

Step-by-step explanation:

V= $\pi *r^{2}*\frac{h}{3}$ is the original volume of a cone formula.

If the radius is multiplied by 6 the new formula is:

V= $\pi *(6x)^{2} * \frac{4}{3}$

Which is simplified to:

V= $\pi *36r^2*\frac{h}{3}$

The only difference between the simplified formula and the original is the *36 so the new volume is 36 times larger when the radius is multiplied by 6.

What number is 1000 larger than 1000

Nata [24]

Answer:

2000

Step-by-step explanation:

Increase 1000 by 1000 in addition.

Modeled in an equation, the situation is 1000 + 1000.

1000 + 1000 = 2000
