If A = (10, 4) and B = (2, 19) what is the length of AB

Amanda [17]

Hello,

Answer:

The length of AB is 17

Step-by-step explanation:

$AB = \sqrt{(x_{B} -x_{A} ) {}^{2} + (y_{B} -y_{A} ) {}^{2} }$

$AB = \sqrt{(2 - 10) { }^{2} + (19 - 4) {}^{2} }$

$AB = \sqrt{( - 8) {}^{2} + (15) {}^{2} }$

$AB = \sqrt{64 + 225}$

$AB = \sqrt{289}$

$\boxed{AB = 17}$

1. Tom thought of a natural number, multiplied all its digits and after that he multiplied the result by the initial number. Is

mihalych1998 [28]

Answer:

1. No

2. 7

3. b=54

Step-by-step explanation:

1. We can answer this by assuming a number.

Let our number be 23

Multiplying its digits = 6

Multiplying the result with initial number = 6 * 23 = 138

So it is not possible to get 1716 as a result by thinking of a natural number and applying the operation mentioned in the question.

2. What is the largest prime factor of the factorial 49! ?

First of all we have to define prime factors:

Prime factors are the prime numbers that can be multiplied together to equal the original number.

The factors of 49 are: 1, 7, 49

7 is the largest prime factor of 49

3. The GCD(a, b) = 18, LCM(a, b) = 108. If a=36, findb.

We will use the relationship:

$GCD * LCM = a*b\\18*108=36b\\1944=36b\\b= \frac{1944}{36} \\b=54$
