When using a quadratic equation of the form ax2 +bx+c=0 to find a distance what should be "ignored"

1 answer:

3 0

You should ignore the negative answers because you can't have negative distance. For example, if you are going back 7 feet, you are still going 7 feet. In that situation, the answer would 7 not -7.

What is the length of one leg of the triangle?<br>11 units<br>11/units<br>22 units<br>22/2 units

son4ous [18]

Answer:

The length of one leg of the triangle is 22 units

Step-by-step explanation:

The complete question in the attached figure

Let

x ----> the length of one leg of the triangle

we know that

In the right isosceles triangle of the figure

The cosine of angle of 45 degrees is equal to the adjacent side to angle of 45 degrees divided by the hypotenuse

$cos(45\°)=\frac{x}{22\sqrt{2}}$ ---> equation A

$cos(45\°)=\frac{\sqrt{2}}{2}$ ----> equation B

equate equation A and equation B and solve for x

$\frac{x}{22\sqrt{2}}=\frac{\sqrt{2}}{2}$

$x=\frac{\sqrt{2}}{2}(22\sqrt{2})=22\ units$

therefore

The length of one leg of the triangle is 22 units

What is the median of the set 1,5,8,10,11,12,14,17,19,21,22,23?

Ilia_Sergeevich [38]

The median of this set is 13.

Explanation: we have 12 numbers, so we take the number between number 6 and 7 which are 12 and 14, between 12 and 14 we got 13, so that’s the median.

Anna plants peas in 3/8 of her garden and herbs in 1/8 of it. She divides the rest of the garden into 6 sections. What fraction

alexandr402 [8]

<h2>Hello!</h2>

The answer is: $\frac{1}{12}$

From the statement we know that he planted peas in 3/8 of her garden and herbs in 1/8 of it, it means 1/2 of the garden, and after that, she divided the rest of the garden into 6 sections. We are asked to find the fraction of the original garden is each section, so:

<h2>Calculations:</h2>

For Planted garden

$\frac{3}{8}+\frac{1}{8}=\frac{4}{8}=\frac{1}{2}$

So, she planted 1/2 of the garden, it means that there is another 1/2 free to be divided into 6 sections,

Then,

$\frac{\frac{1}{2} }{6}=\frac{1}{12}$

Therefore,

Each section would be $\frac{1}{12}$ of the original garden.

Have a nice day!

AC is opposite sin(45)=11/BC
BC = 11/sin(45)
BC=11 root 2
