What shows the correct substitution of the values a,b, and c from the equation 0=-3x^2-2x+6

Arlecino [84]

When dealing with a quadratic equation, you usually assign the following name to the coefficients of the variables:

$ax^2+bx+c=0$

So, $a$ is the coefficient of $x^2$ , $b$ is the coefficient of $x$ and $c$ is the constant term.

In your case, the coefficient of $x^2$ is -3, so $a=-3$

The coefficient of $x$ is -2, so $b = -2$

The constant term is 6, so $c = 6$

At a speed of 22 revolutions per minute, how long will it take a wheel of radius 10,

Bogdan [553]

Well, if the radius is 10, then the circumference is $\frac{2*10*22}7=\frac{440}7$
What's the unit? Either way, 22 rev. per minute means each minute you go by $22*\frac{440}7=\frac{9680}7$ units per second. Now you got the linear speed, just find out the time by dividing the distance by the speed!
So, what's the unit for the radius?
