HELP PLZ

Alexxandr [17]

Answer:

$x=\frac{-7-\sqrt{17}}{2}\textrm{ or }x=\frac{-7+\sqrt{17}}{2}$

Step-by-step explanation:

Given:

The equation is given as:

$x^2=-7x-8$

Rearrange the above equation in standard quadratic equation of the form $ax^2+bx+c=0$

Adding $7x + 8$ on both sides, we get

$x^2+7x+8=0$

Here, $a=1,b=7,c=8$

Now, we solve this using quadratic formula,

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\\x=\frac{-7\pm \sqrt{7^2-4(1)(8)}}{2(1)}\\x=\frac{-7\pm \sqrt{49-32}}{2}\\x=\frac{-7\pm \sqrt{17}}{2}\\\\\\\therefore x=\frac{-7-\sqrt{17}}{2}\textrm{ or }x=\frac{-7+\sqrt{17}}{2}$

PLZ help me super really really fast

maria [59]

Answer:

A. 3 cm

Step-by-step explanation:

The smallest face has the sides 4 cm and 8 cm. If the water is 4 cm from its top, then the height of the water is $16-4=12$ cm and the volume of the water is

$V_{water}=4\cdot 8\cdot 12=384\ cm^3$

The largest face has the sides 8 cm and 16 cm. If the container is placed on its largest face, then the volume of the water is

$V_{water}=8\cdot 16\cdot h \ cm^3,$

where h is the height of the water.

Equate volumes of the water:

$8\cdot 16\cdot h=384\\ \\h=\dfrac{384}{8\cdot 16}=3\ cm$

Therefore, the water is 3 cm from the bottom.

HELP!! Identify the transformation from ABC to A'B'C'.

elena55 [62]

Answer:

Thus, the transformation from ABC to A'B'C' is a reflection over the x-axis.

Choice 1.

Step-by-step explanation:

Reflection over the x-axis

Given a point A(x,y), a reflection over the x-axis maps A to the point A' with coordinates A'(x,-y).

The figure shows triangles ABC and A'B'C'. It can be clearly seen the x-coordinates for each vertex of both triangles is the same and the y-coordinate is the inverse of it counterpart. For example A=(5,3) and A'=(5,-3)

Thus, the transformation from ABC to A'B'C' is a reflection over the x-axis.

Choice 1.
