Solve this quadratic equation using the quadratic formula.<br> 5 - 10x - 3x2 = 0
Olegator [25]

-3x^2 - 10x + 5 = 0

Quadratic formula:

-b +/- sqrt[b^2 - 4(a)(c)]/2(a)

So. . . 10 +/- sqrt[(10^2) - 4(-3)(5)]/2(-3)

10 +/- sqrt[100+60]/ -6

10 +/- sqrt[160]/-6

A desk is 2 meters long and 1 meter wide. The desk needs to be represented in a scale drawing of an office that uses a scale of
Strike441 [17]

Answer:

<em>Thus, the dimensions of the desk in the drawing are 4 cm long and 2 cm wide.</em>

Step-by-step explanation:

<u>Scaling</u>

The scale factor established to represent a desk 2 meters long and 1 meter wide is:

1 centimeter = 0.5 meter

We need to convert the real dimensions to the scaled dimensions. To complete the task, it's a good idea to multiply the real dimensions by the ratio:

\displaystyle \frac{1\ cm}{0.5\ m}

to get the scaled dimensions.

The length of 2 meters is scaled to:

\displaystyle 2\ m\frac{1\ cm}{0.5\ m}=4\ cm

And the width of 1 meter is scaled to:

\displaystyle 1\ m\frac{1\ cm}{0.5\ m}=2 cm

Thus, the dimensions of the desk in the drawing are 4 cm long and 2 cm wide.

Using the given points, determine the slope. (5,-6)and(2,15)
Hunter-Best [27]
Subtract the y-coordinates. This is the rise.
Subtract the x-coordinates in the same order. This is the run.
Slope = rise/run.

Subtract the y-coordinates: -6 - 15 = -21. rise = -21
Subtract the x-coordinates in the same order:5 - 2 = 3. run = 3

slope = rise/run = -21/3 = -7
