The estimated velocity v (in miles per hour) of a car at the end of a drag race is v=234\sqrt[3]{p/w} , where p is the horsepowe

Dennis_Churaev [7]

Answer:

299 miles per hour

Step-by-step explanation:

$v=\frac{234}{\sqrt[3]{\frac{p}{w}}}$

$v=\frac{234}{\sqrt[3]{\frac{1311}{2744}}}$

$v\approx299$

Therefore, the velocity of the car at the end of a drag race is 299 miles per hour

How do i factor x^4+6x^2-7 completly?

liq [111]

The factoring can be done similarly to a quadratic equation thanks to x^4 being the square value of x^2.

<span>x^4 + 6x^2 - 7
x^4</span><span> - x^2</span> + 7x^2 - 7
(x^4 - x^2) + (<span>7x^2 - 7)
</span>x^2(x^2 - 1) + 7(<span>x^2 - 1)
</span>(x^2 + 7)(x^2 - 1)
<span>(x^2 + 7)(x - 1)(x + 1)
</span>
Factored completely we get: <span>(x^2 + 7)(x - 1)(x + 1)</span>

What are the roots of the quadratic equation below 3x2+15x-5=0

fomenos

Answer:

Step-by-step explanation:

$3x^2+15x-5=0\\a = 3\\b = 15\\c = -5\\ x = -b\±\frac{\sqrt{b^{2} -4ac} }{2a} \\x = -(15)\±\frac{\sqrt{15^{2} -4(3)(-5)} }{2(3)} \\x = -15 \±\frac{\sqrt{225+60} }{6} \\x = -15\±\frac{\sqrt{285} }{6} = A$
