area of yellow triangle is 35 square units.

Angle CAD can be equal to angle CBE.  If angles CAD and CBE are not equal, then we can choose a point A' on AD so that angle CA'D is equal to CBE.  So we can move point A to A', and then angles CAD and CBE will be equal.

7*6= 42, 7*7= 49, 7*8=56 so 8 is ur answer!

using long division 5666/2381 is about 2.379

(89)2/3= ???AU

Cannot figure out how getting AU

The n such that n = 10389 (mod 12) is n = 2.

Three circles fit inside a square as shown where two small circles touch a large circle. Given that the radius of the small circles is 3 and the side length of the square is 14, find the radius of the larger circle 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Square side = 14             small radius r = 3             big radius R = ?

The distance between the centers of the small circles is 8 units.

So, we have       4² + (11 - R)² = (3 + R)²          R = 32 / 7    or   R ≈ 4.57 

By the quadratic formula, t = 4.8 seconds.

Oh okay! Thank you!

A rotation is of the form y - c = e^(i*theta)*(z - c).  Solving for c, we get c = 5 - 2i.

where you get the 87 from

or:

5666/2381 = 2.379672406551869

Nope....it is correct given the info in the Q

   1600 * 1.13 * .87 = $1572.96   at the end of two years (13% up the first year then down 13% the 2nd)

"a"  cannot be   -1     because   x^2 -  x + 1    = 0    has no  real roots  (the discriminant is <  0  )

Correct.....

Let the center of the  large circle  be   =  (7,R)

Then the  center of   one of the  small circles   is  (11, 11)

So  the square of the distance   between  these two points  is   (R + 3)^2

So

(7-11)^2  + (11  - R)^2  =   (R + 3)^2

4^2  + R^2   -  22R + 121 =   R^2  + 6R  + 9     simplify

137 - 22R  =  6R + 9

137  - 9  =  28R

128  = 28R

128/28 =  R  =  32/7

5666 divided by 2381 is equal to 2 with a remainder of 904

Wrong

$ 1600 x 1.13 x .87 = $ ........

10% off means you pay 90 % of the original price

$ 85 * .95  * (1.10) = $ .......   final price  

But a=-1 is incorrect btw

The ratio is 2 : 1

10 percent off would mean the price is 90% of the original price.

A ten percent sales tax would be an additional 9%, making it 99% of the original price

85*.99=84.15

Thx bro! Is that the only value

anyways I got a=-1, 2 by using the quadratic formula on both, setting them equal and then solving for a, then changing the plus minus signs for all possibilities of signs,
