Answer:

The terms have a common ratio of - 1.5

Step-by-step explanation:

4.8 - ( - 3.2 )

= 4.8 + 3.2

= 8

- 7.2 - 4.8

= - 12

Common difference is not same.

4.8 / - 3.2

= - 4.8 / 3.2

= ( - 4.8 / 16 ) / ( 3.2 / 16 )

= - 3 / 2

= - 1.5

- 7.2 / 4.8

= ( - 7.2 / 24 ) / ( 4.8 / 2.4 )

= - 3 / 2

= - 1.5

Common is ratio is same.

Answer,

The terms have a common ratio of - 1.5

Find the coordinates of point Q that is 2/3 of the way along the directed segment from R(-7,-2) to S(2,4)

Eva8 [605]

The coordinates of point Q that is 2/3 of the way along the directed segment from R(-7,-2) to S(2,4) is $(\frac{-17}{5} ,\frac{2}{5} )$

Explanation :

the coordinates of point Q that is 2/3 of the way along the directed segment from R(-7,-2) to S(2,4)

Apply section formula to find coordinates of point Q

$(\frac{mx_2+nx_1}{m+n} , \frac{my_2+ny_1}{m+n} )$

Ratio m:n is 2:3 and point R is (x1,y1) , point S is (x2,y2)

Substitute all the values inside the formula

$(\frac{2(2)+3(-7)}{2+3} , \frac{2(4)+3(-2)}{2+3} )\\\\(\frac{-17}{5} ,\frac{2}{5} )$

The coordinates of point Q is $(\frac{-17}{5} ,\frac{2}{5} )$

You found the prime factorization of the number 73 explain how you can check your answer

antoniya [11.8K]

9514 1404 393

Explanation:

You can check your answer by making sure that each of the primes you found is actually a prime. (Compare to a list of known primes, for example.) After you have determined your factors are primes, multiply them together to see if the result is 73. If so, you have found the correct prime factorization.

<em>Additional comment</em>

73 is prime, so its prime factor is 73.

73 = 73
