Part 1)<span>

<span>Let's divide this problem into three shape and next we will compute the area for each shape:</span>

(1) First triangle
(2) Rectangle
(3) Second Triangle

(1) The best known and simplest formula is:

A_{1}= \frac{bh}{2}

<span>where b</span> is the length of the base of the triangle, and h is the height or altitude of the triangle. Using trigonometry the base is given by:

H= \frac{4}{sin(45)}=4\sqrt{2}

b=Hcos(45)=4\sqrt{2}cos(45)=4

Therefore:

<span>A_{1}= \frac{4\times 4}{2}=8cm^{2}</span>

(2) The area of a rectangle is given by:

A_{2}=L1 \times L2 = 8 \times 4=32cm^{2}

(3) This is also a triangle, so:

<span>A_{3}= \frac{2\times 4}{2}=4cm^{2}</span>

The total are is:

<span>A=A_{1}+A_{2}+A_{3}= (8+32+4) \rightarrow \boxed{A=44cm^{2}}</span>

Part 2)<span>
</span>
If you know the lengths of the two diagonals of a kite, the area is half the product of the diagonals. So:

</span>A= \frac{d_{1}d_{2}}{2}= \frac{10.2 \times 8}{2} \rightarrow \boxed{A=40.8ft^{2}}<span>
</span>

The function f(x) is given by the set of ordered pairs. {(1,0), (–10,2), (0,6), (3,17), (–2,–1)} Which equation is true? f of ne
Rudik [331]

Answer:

f(0)=6

Step-by-step explanation:

When representing function's values by set of ordered pairs, the first one correspond to the x value and the second to the image or "y" value.

When you read f(0) means "when x is 0" then the 6 is the value of the function or the image.

Two trains leave a town at the same time heading in opposite directions. One train is traveling 12 mph faster than the other. Af
vichka [17]

Answer:

Step-by-step explanation:

I'm going to paint you a picture in words of what this looks like on paper.  We have a train leaving from a point on your paper heading straight west.  We have another train leaving from the same point on your paper heading straight east.  This is the "opposite directions" that your problem gives you.  

Now let's make a table:

                 distance       =        rate      *       time

Train 1

Train 2

We will fill in this table from the info in the problem then refer back to our drawing.  It says that one train is traveling 12 mph faster than the other train.  We don't know how fast "the other train" is going, so let's call that rate r.  If the first train is travelin 12 mph faster, that rate is r + 12.  Let's put that into the table

               distance        =        rate        *        time

Train 1                                        r

Train 2                                    (r + 12)

Then it says "after 2 hours", so the time for both trains is 2 hours:

           

               distance        =        rate        *        time

Train 1                                        r           *          2

Train 2                                  (r + 12)       *          2

Since distance = rate * time, the distance (or length of the arrow pointing straight west) for Train 1 is 2r.  The distance (or length of the arrow pointing straight east) for Train 2 is 2(r + 12) which is 2r + 24.  The distance between them (which is also the length of the whole entire arrow) is 232.  Thus:

2r + 2r + 24 = 232 and

4r = 208 so

r = 52

This means that Train 1 is traveling 52 mph and Train 2 is traveling 12 miles per hour faster than that at 64 mph

HELPPPPPP WILLLL GIVE EXTRAAA POINTSSS AND BRAINLIEST JUST FOR THE ANSWERS SAY THE WHOLE THING SO ITS EASIER
nadezda [96]

<u>Here are your fill-ins:</u>

r = 1 is a zero, so (r-1) is a factor.

r = -1 is a zero, so (r+1) is a factor.

The remainders from synthetic division are 0 each time.

See the attachment for the synthetic division numbers.

_____

The reduced quadratic is ...

... x² -6x +13 = 0

Solving by completing the square, we have ...

... (x -3)² = -4

... x = 3 ± 2i

_____

The quadratic formula would tell you ...

... x = (-(-6) ± √((-6)² -4(1)(13)))/(2·1) = (6±√-16)/2 = 3±2i
