Find the coordinates of P so that P partitions the segment AB in the ratio 1:7 if A(7,14) and B(−1,−2).

love history [14]

Answer:

P(6, 12 )

Step-by-step explanation:

Using the Section formula, then

$x_{P}$ = $\frac{7(7)+1(-1)}{1+7}$ = $\frac{49-1}{8}$ = $\frac{48}{8}$ = 6

$y_{P}$ = $\frac{7(14)+1(-2)}{1+7}$ = $\frac{98-2}{8}$ = $\frac{96}{8}$ = 12

Hence P(6, 12 )

Lyrx [107]

Answer: See explanation

Step-by-step explanation:

Your question isn't complete but let me give different scenarios to help you solve.

Firstly, assuming we want to calculate the amount of items left after the large items are carried alone, this will be:

= 561 - 36

= 525

Secondly, if we want to know the percentage of the large items that will be carried alone. This will be:

= 36/561 × 100.

= 6.42%

Thirdly, if you want to know the percentage of the items that will be left after the large ones have been carried alone. This will be:

= 100% - 6.42%

= 93.58%
