A billiard ball is struck by a cue. It travels 120 cm before ricocheting off a rail and traveling another 100 cm into a corner pocket. The angle between the path as the
ball approaches the rail and the path after it strikes the rail is 40 degrees. How far is
the corner pocket from where the cue initially struck the ball? Round your answer to the nearest centimeter.

Answers

The angle between incident and reflection is 45 degrees not 90 degrees, so we need to use the cosine rule:
 
a^2 = 100^2 + 120^2 - 2*100*120*cos(45°)   where a is the distance  between pocket and initial strike.
 
so a = sqrt(100^2 + 120^2 - 2*100*120*cos(45°))
 
a = 86 cm (to the nearest cm).

Factor the polynomial completely.

9g^2 - 30gh + 25h^2

Answers

Answer:

Step-by-step explanation:

It's a perfect square.

It factors into (3g - 5h)^2

or (3g - 5h)(3g - 5h)

Make sure it is correctly factored.

3g*3g = 9g^2

3g * - 5h  = - 15gh

-5h*3g = - 15gh

5h*5h = 25h^2

These four terms add to 9g^2 - 15gh - 15gh + 25h^2 = 9g^2 - 30gh + 25h^2 which is exactly what you started with.

What is the area of the quadrilateral?​

Answers

Answer:

area=w h

Step-by-step explanation:

when a two digit number is multiplied by its unit digits, the product is 336. When the digits are reversed and the new number is multiplied by its new unit digits, the product is 325.If the sum of the digits is 11, find the original two digit number​

Answers

9514 1404 393

Answer:

  56

Step-by-step explanation:

In the base-10 number system, the only two digits that have themselves as the least significant digit of their square are 5 and 6.* If multiplying a 2-digit number by the ones digit gives a ones-digit of 6, then the ones digit must be 6.

Similarly, if the ones digit of the product is 5, the ones digit of the number must be 5.

So, the ones digit of the original number is 6, and the ones digit of the reversed 2-digit number is 5. The original number is 56.

__

Check

  56 × 6 = 336

  65 × 5 = 325

  5 + 6 = 11

_____

* Additional comment

These digits are called "automorphs." Automorphs ending in 5 or 6 can be extended to any number of digits. For example, the 3-digit automorph ending in 6 is 376. 376² = 141376. Similarly, the 3-digit automorph ending in 5 is 625. 625² = 390625

convert the following statement into equation five time a number decreased by 2 is equal to 4​

5x-2=4

Step-by-step explanation:

:DD

5x - 2 = 4
Which is:
5x - 2 = 4
5x = 6
x = 6/5

The statement could mean this:
5(x - 2) = 4
5x - 10 = 4
5x = 14
x = 14/5

Angle M = 4y + 3 = 4(15) + 3 = 63

Angle N = 6y + 6 = 6(15) + 6 = 96

Nathan Leopold and Richard Loeb, August 2225, 1924I well remember that I have been a child. And while youth has its advantages, it has its grievous troubles. There is an old prayer, "Let us grow old in years, but retain the heart of a child"the heart of a child with its strong emotion, with its abundant life, with its disregard of consequences, with its living in the moment and for the moment and for the moment alone, with its lack of responsibility, with its freedom from care.What do we know about childhood? The brain of the child is the home of dreams, of castles, of visions, of illusions and of delusions. In fact, there could be no childhood without delusions, for delusions are always more alluring than the fact. Delusions, dreams and hallucinations are a part of the warp and woof of childhood.
