Answer:

  √2 and √5 and their difference are all real numbers

Step-by-step explanation:

In looks like you want to know if the difference ...

   \sqrt{2}-\sqrt{5}

is a real number.

The square root of a non-negative number is a real number. The sum or difference of real numbers is a real number.

The sum you have indicated is a real number, approximately ...

  √2 -√5 ≈ 1.4142 -2.2361 ≈ -0.8219

15 and 17 pls.. 15 points!!!!
Maurinko [17]

Step-by-step explanation:

15) 50 ÷ 2 = 25

17) Mean = 301, Mode = 40-50

(10+20) ÷ 2 = 15, (20+30) ÷ 2 = 25, (30+40) ÷ 2 = 35

(40+50) ÷ 2 = 45, (50+60) ÷ 2 = 55, (60+70) ÷ 2 = 65

(70+80) ÷ 2 = 75

• 15×4 = 60, 25×8 = 200, 35×10 = 350, 45×12 = 540

55×10 = 550, 65×4 = 260, 75×2 = 150

Mean = (60+200+350+540+550+260+150) ÷ 7

= 2110 ÷ 7

= 301.4285....

= 301

Mode : the highest frequency

If NQZ ~ CBK, find BK<br><br> Look at picture
nevsk [136]

Answer:

BK=39/7

Step-by-step explanation:

because NQZ~CBK

so BK/QZ = TZ/KF

(4x+1)/(2x+7) = 27/45 = 3/5

5(4x+1) = 3(2x+7)

20x + 5 = 6x + 21

14x = 16

x = 8/7

=> BK = 4(8/7)+1 = 39/7

I need help with geometry.
Dahasolnce [82]
1.

In any trapezoid, the length of the midsegment is \frac{|base_1|+|base_2|}{2}

substituting the known values:

\frac{24+|base_2|}{2}=19

24+|base_2|=38

|base_2|=38-24=14

2.

Notice that since D and have the same y-coordinate, then DE is horizontal, and since F and D have the same x-coordinate, FD is vertical.

Thus FD and DE are perpendicular, so the triangle FED is a right triangle.

The median drawn from the right angle, is equal to half the hypotenuse.

That is, |DO|=1/2 |FE|, thus |OE|=|OF|=|OD|, are all radii of the circle centered at O.

O is the midpoint of EF, and is found by the Midpoint formula:

O=( \frac{1+7}{2} , \frac{5+1}{2} )=(4, 3)


Answer:

1. 14

2. (4, 3)
