Answer:

Brandyn is 41.48m from Chris

Step-by-step explanation:

I have drawn an image depicting this question and I've attached it.

From the diagram, chris is standing at point B while Brandyn is at point D. x is the distance of brandyn to the bottom of the pole.

The height of the pole is AC.

Now, by trigonometric ratio, we can find AC. Thus;

AC/20 = tan 35

AC = 20 tan 35

AC = 14

Since,we now have AC, we can find x.

Similarly, 14/x = tan 27

x = 14 / tan 27

x = 27.48 m

Thus, total distance of brandyn from Chris = 14 + 27.48 = 41.48 m

Let f(x)=x+8and g(x)=x^2-6x-7. Find f(g(2))
posledela

The answer is a. -7


1. Find g(2).

2. Find f(g(2)).

g(x) = x² - 6x - 7

x = 2 ⇒ g(2) = ?

g(2) = 2² - 6·2 - 7 = 4 - 12 - 7 = -15

2. f(x) = x + 8

g(2) = -15

f(g(2)) = f(-15) = -15 + 8 = -7

What is the simplest form of 6/27?
aivan3 [116]
The fraction 6/27 is equivalent1 to 2/9.

This is a proper fraction once the absolute value of the top number or numerator (6) is smaller than the absolute value of the bottom number or denomintor (27).

<h3 /><h3>Comparing sides AB and DE </h3>

AB =

\sqrt{ {1}^{2} +  {1}^{2}  }

=  \sqrt{2}

DE

= \sqrt{ {(3 - 5)}^{2} +  {(1 + 1}^{2}  }  \\   = \sqrt{ {( - 2)}^{2}  +  {(2)}^{2} }  \\    = \sqrt{4 + 4}  \\  =  \sqrt{8}  \\   = 2 \sqrt{2}

So DE = 2 × AB

and since the new triangle formed is similar to the original one, their side ratio will be same for all sides.

<u>scale factor</u> = AB/DE

= 2

It's been reflected across the Y-axis

<em>moved thru the translation of 3 units towards the right of positive x- axis </em>

for this let's compare the location of points B and D

For both the y coordinate is same while the x coordinate of B is 0 and that of D is 3

so the triangle has been shifted by 3 units across the positive x axis
