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:

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

$a = 3, b = k, c = 3$

$\bigtriangleup = b^{2} - 4ac$

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

$\bigtriangleup = k^{2} - 36$

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.

Given the speeds of each runner below, determine who runs the fastest.

alexandr402 [8]

Answer:

Brooke

Step-by-step explanation:

We can solve this by figuring out how far each person runs a second

Stephanie runs 12 feet a second so nothing needs to be done here

Liz runs 306 feet in 38 seconds. To solve for the distance ran in 1 second we can divide (306/38)= around 8 feet

Will runes 1 mile in 491 seconds. A quick search will tell use that 1 mile is equal to 5280 feet and 5280/491 = 10.75

Brooke runs 851 feet in 1 minute or 60 seconds. 851/60 =14.18

Brooke obviously runs the furthest in one second and therefore she's the fastest runner

Ramona has a new job as a chef. She earns the same

DaniilM [7]

Answer:

y = 10x + 100

Step-by-step explanation:

Given the information:

She earns the same amount per hour as she did in her old job $ 100 sign-on bonus

=> the equation for line p in the form y= mx where:

x is the number of hour she worked

y the money she earned

=> the equation for line q in the form y= mx + 100 ($ 100 sign-on bonus )

From that, we see that the two equations have the same slope or you can use a transformation to map line p onto line q

We can create two points (0, 0) and (2, 20) are on line p

<=> m = $\frac{y2-y1}{x2-x1} = \frac{20-0}{2-0} = 10$

The equation for line p is y = 10x

=>The equation for line q should include the hourly earnings at the

new job plus the sign-on bonus. The equation is y = 10x + 100

Hope it will find you well.
