Recall that the quadratic formula states that, the solutions to the quadratic equation

ax^2+bx+c=0

are

\frac{-b\pm\sqrt{(-b)^2-4ac}}{2a}.

Now, in the given equation, a=-1 ,b=-6, and c= 8. Therefore, the solutions to the equation are:

x=\frac{6\pm\sqrt{36+32}}{-2}.

Simplifying the above result, we get:

x=-3\pm(-1)\sqrt{17}.

Answer:

\begin{gathered} x_1=-3+\sqrt{17,} \\ x_2=-3-\sqrt{17}. \end{gathered}

there are three consecutive odd integers. Three times the largest is 7 times the smallest. WHat are the integers
Elena L [17]

Answer:

3, 5, 7

Step-by-step explanation:

We can assign the first number as x. Since all the numbers are odd the next number will be x+2, and the last will be x+4.

3*(x+4) = 7(x)

3x+12 = 7x

12 = 4x

x = 3

x+2 = 5

x+4 = 7

18.There is no battery in this simulation. Move the magnet with the N pole toward the loops (coils) connected to the light bulb
astraxan [27]

Answer:

Step-by-step explanation:

Whenever a magnetic field linked to loop changes, the current is induced in the loop which sequentially opposes the cause of change in magnetic flux. So whenever the magnet moves towards and away from the loop then it causes the current to induce in the loop to oppose the change in magnetic flux by effectively creating a similar pole that is coming towards the loop.

For example, if the magnet north pole is coming towards loops then it effectively creates a north pole in front of the magnet.

So flow of current will glow the light bulb.

Evaluate 5x²-3(x-2)+x for x=3​
Zepler [3.9K]

Answer:

45

Step-by-step explanation:

Evaluate 5 x^2 - 3 (x - 2) + x where x = 3:

5 x^2 - 3 (x - 2) + x = 5×3^2 - 3 (3 - 2) + 3

3^2 = 9:

5×9 - 3 (3 - 2) + 3

3 - 2 = 1:

5×9 - 3 + 3

5×9 = 45:

45 - 3 + 3

45 + 3 = 48:

48 - 3

| 4 | 8

- | | 3

| 4 | 5:
