Answer:

\pm i\sqrt{38}

Step-by-step explanation:

Given radical is \pm \sqrt{-38}

We can rewrite the radical as,

\pm\sqrt{-38}=\pm(\sqrt{-1}\times \sqrt{38})

            =\pm(i\sqrt{38})

(Since, i = \sqrt{-1})

Therefore, simplified form of the given radical will be,

\pm \sqrt{-38}=\pm i\sqrt{38}

The height of Mountain P is 1,086 feet.The height of Mountain Q is 4 times the height of Mountain P.The area model shown below r
earnstyle [38]

Answer:

A=4000, B=80, C=24

Step-by-step explanation:

You forgot to put the correct area model, I attached it to the answer.

We have the fact that Mountain Q is 4 times the height of Mountain P. That's the "4" we have in the left side of our model. It's like having a multiplication table, next to the "4" we have "A" and upper this we have "1000", the only thing we have to do is multiplify 4*1000=4000. The next letter we have is B and below it we have "320", we divided it by 4, 320/4=80. The last letter we have is C, and is below a "6", we only have to multiplify it by 4, 6*4=24.

At the end we only sum our

  • A + 320 + c = 4344 (4 times the height of Mountain P).
  • 1000 + B + 6 = 1086(the height of the Mountain P).

At a certain time of day, a tree 15 m tall cast a shadow of 12 m, while a second tree cast a shadow of 20 m. How tall is the sec
lilavasa [31]

25 metres tall.

Explanation:

The heights of the trees are directly proportional to the length of their shadows because at the same time of day, the sun will be at the same angle in the sky.

The trees and their shadows form 2 similar triangles:
Write as a proportion:

<span><span>heightshadow</span> <span>x20</span>=<span>1512</span></span>

<span>12x=20×15</span>

<span>x=<span><span>20×15</span>12</span></span>

<span>x=25</span> metres tall.

As check: find the constant for each tree:

<span><span>1512</span>=1.25 and <span>2520</span>=<span>1.25</span></span>

Give an example of an odd function and explain algebraically why it is odd.
tatuchka [14]

An odd function is a function of a form y=x^n where n is an odd number.

Some examples would be functions:

y=x,y=x^3,\dots.

A formal definition of odd function is the following.

(Algebraic proof).

Let f:\mathbb{R}\to\mathbb{R} (real function).

The function is odd if the below equation is true for all x and -x for which the function is defined:

f(x)=-f(-x).

Hope this helps.
