FIND THE UNIT RATE AND ROUND TO THE NEAREST HUNDREDTHS IF NECESSARY. Jasigreen's class opened last year and serviced 6,840 custo
Vladimir [108]
<span>6840 customers ... 45 days<span>
x customers = ? ... 1 day

If you would like to know how many customers were in Jasigreen's class in 1 day, you can calculate this using the following steps:

6840 * 1 = 45 * x
6840 = 45 * x     /45
x = 6840 / 45
x = 152 customers

<span>The correct result would be </span>152 customers<span>.</span></span></span>

3x^2+kx=-3 What is the value of K will result in exactly one solution to the equation?
Scorpion4ik [409]

Answer:

For k = 6 or k = -6, the equation will have exactly one solution.

Step-by-step explanation:

Given a second order polynomial expressed by the following equation:

ax^{2} + bx + c, a\neq0.

This polynomial has roots x_{1}, x_{2} such that ax^{2} + bx + c = (x - x_{1})*(x - x_{2}), given by the following formulas:

x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}

x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}

\bigtriangleup = b^{2} - 4ac

If \bigtriangleup = 0, the equation has only one solution.

In this problem, we have that:

3x^{2} + kx + 3 = 0

So

a = 3, b = k, c = 3

\bigtriangleup = b^{2} - 4ac

\bigtriangleup = k^{2} - 4*3*3

\bigtriangleup = k^{2} - 36

We will only have one solution if \bigtriangleup = 0. So

\bigtriangleup = 0

k^{2} - 36 = 0

k^{2} = 36

k = \pm \sqrt{36}

k = \pm 6

For k = 6 or k = -6, the equation will have exactly one solution.
