Which values of c will cause the quadratic equation –x2 3x c = 0 to have no real number solutions? check all that apply.

nika2105 [10]

The given quadratic equation will not have any real solution for c<-9/4.

The given quadratic equation is:

$-x^{2} +3x+c=0$

<h3>What is a quadratic equation?</h3>

Any equation of the form $ax^{2} +bx+c=0$ is called a quadratic equation with a≠0.

In order to have no real solution, the discriminant of a quadratic equation will be less than zero.

$D < 0$

$3^{2} -4(-1)(c) < 0$

$9+4c < 0$

$c < -\frac{9}{4}$

For $c < -\frac{9}{4}$ the given quadratic equation will have no real solutions.

Hence, the given quadratic equation will not have any real solution for c<-9/4.

Find the missing term. If y = 1 + i, then y3 − 3y2 + ( ? ) − 1 = -i .

attashe74 [19]

$y=1+i\qquad\qquad i^2=-1\\\\\\
y^3-3y^2+(?)-1 =-i\\\\(1+i)^3-3\cdot(1+i)^2+(?)-1+i=0\\\\1^3+3i+3i^2+i^3-3\cdot(1^2+2i+i^2)+(?)-1+i=0\\\\
1+3i+3\cdot(-1)+i\cdot i^2-3-6i-3i^2+(?)-1+i=0\\\\
1+3i-3+i\cdot(-1)-3-6i-3\cdot(-1)+(?)-1+i=0\\\\
1+3i-3-i-3-6i+3+(?)-1+i=0\\\\
-3-3i+(?)=0\\\\(?)=3+3i\\\\(?)=3(1+i)\\\\\boxed{(?)=3y}$

Jillian walked 0.5 miles before she started jogging at an average pace of 5 miles per hour. The equation d = 0.5 + 5t can be use

castortr0y [4]

Answer:

The answer is option 2.

Step-by-step explanation:

In the question, the independent variable is time and dependent is distance. As the time changes, the distance will also change it means the distance depends on time.

For example,

$d = 0.5 + 5t$

Let t = 1,

$d = 0.5 + 5(1)$

$d = 5.5 \: miles$

Let t = 5,

$d = 0.5 + 5(5)$

$d = 25.5 \: miles$

Therfore, as time increases, distance will also increase.
