Effectus [21]3 years ago
6 0

9514 1404 393

Answer:

  120

Step-by-step explanation:

The function C(n, k) can be written in terms of factorials:

  C(n, k) = n!/(k!(n -k)!)

Then ...

  C(16, 2) = 16!//(2!(16 -2)!) = (16·15)/(2·1)

  C(16, 2) = 120

Question: A square with sides of length 5 is positioned inside a square with sides of length 7. What is the total area between t
Sergio [31]

Answer:

The total area between the squares is of 24 units squared.

Step-by-step explanation:

Area of a square:

The area of a square of side length l is given by:

A = l^2

Area between figures:

The area between two figures is the area of the larger figure subtracted by the area of the smaller figure.

Larger square:

Square with side of length 7. So

A_l = 7^2 = 49

Smaller square:

Square with side of length 5. So

A_s = 5^2 = 25

What is the total area between the squares? ​

T = A_l - A_s = 49 - 25 = 24

The total area between the squares is of 24 units squared.

PLEASE HELP!!!<br>Simplify the expression and show your work<br><br>sqrt110x^17y^12
leonid [27]

Answer:

Step-by-step explanation:

10y2 - 17y + 12 = y + 16

10y2 - 17y + 12 - 16 = y

10y2 - 17y - 4 = y

10y2 -17y - y -4 = 0

10y2 -16y - 4 = 0

Now put formula

x = -b +- (square root) b2 - 4ac

                 2a

a = 10 b= -16 c= -4

y = -(-16) +- (square root) -16 - 4 (10) (-4)

                             2(10)

y = 16 +- (square root) -16 - 400

                                20

y = 16 +- (square root) -416

                         20

y = 16 +- 20.396

              20

Now this +- is the plus minus thingy in which two answers come

The first we will do is +

16 + 20.396                                         16 - 20.396

  20                                                             20

= 1.8198                                                           = -0.2198
