Deborah hikes due south for 3 miles. She then turns due west and hikes 4 miles. What is the shortest distance between the starti
Cerrena [4.2K]

Answer:

  5 miles

Step-by-step explanation:

The two legs of Deborah's hike form the right-angle legs of a right triangle. The shortest distance is then the hypotenuse of that triangle, found using the Pythagorean theorem.

  d^2 = 3^2 + 4^2 = 9 +16 = 25

  d = √25 = 5

Deborah ends 5 miles from her start.

current rules for telephone area codes allow the use of digits 2-9 for the first digit and 0-9 for the second and third digits.
lukranit [14]
In this question, there are 10 digit phone number which was divided into 3-3-4 digits. Every first digit of the division should be 2-9 which mean only 8 possibilities. The other digits would be 0-9 which mean 10 possibilities. Then the calculation would be:

8*10*10   *    8*10*10    *   8*10*10*10  = 8^3 * 10*7= 512 * 10^7= 5.12 * 10^9

If you convert <span>400,000,000 into the scientific form it will become 4* 10^8. Since 5.12*10^9 > 4 * 10^8, then it is clear that the number should be enough</span>

How would you factor a quadratic expression like 9x^2-4
Ganezh [65]

Hello, we need to see it as a difference of two squares as we know that for all a and b real numbers

a^2-b^2=(a-b)(a+b)

So, here

9x^2-4=(3x)^2-2^2=(3x-2)(3x+2)

Voila !

Thank you
