Answer:

<h2>no real solution</h2>

Step-by-step explanation:

$-3x^2-4x-4=0\qquad\text{change the signs}\\\\3x^2+4x+4=0\\\\\text{use the quadratic formula:}\\\\\text{for}\ ax^2+bx+c=0\\\\\text{if}\ b^2-4ac0,\ \text{then an equation has two solutions:}\ x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

$\text{We have}\ a=3,\ b=4,\ c=4.\\\\\text{Substitute:}\\\\b^2-4ac=4^2-4(3)(4)=16-48=-32$

A cone with volume 246 ft cubic if the height is 15 find the radius

Liula [17]

Answer:

r = 3.95 ft

Step-by-step explanation:

Volume of cone = $\frac{1}{3} \pi r^{2} h$ = 246 ft³

246 = $\frac{1}{3} * \frac{22}{7} * r^2 * 15$

r² = $\frac{246*3*7}{22*15*5}$

r = $\sqrt{15.65}$

r = 3.95 ft
