What are the coordinates of point B on AC Such that the ratio of AB to AC is 5:6

Oksi-84 [34.3K]

Answer:

$\vec B = \left(x_{A}+\frac{5}{6}\cdot (x_{C}-x_{A}), y_{A}+\frac{5}{6}\cdot (y_{C}-y_{A}), z_{A}+\frac{5}{6}\cdot (z_{C}-z_{A})\right)$

Step-by-step explanation:

Let suppose that A, B, and C have the following points with respect to origin in the Euclidean space:

$\vec A = (x_{A}, y_{A}, z_{A})$

$\vec B = (x_{B}, y_{B}, z_{B})$

$\vec C = (x_{C}, y_{C}, z_{C})$

Besides, let consider that locations of A and B are currently known. The ratio is:

$\frac{AB}{AC} = \frac{5}{6}$

$AB = \frac{5}{6} \cdot AC$

Vectorially speaking, expression can be rewritten in the following terms:

$\overrightarrow{AB} = \frac{5}{6}\cdot \overrightarrow{AC}$

$(x_{B}-x_{A}, y_{B}-y_{A}, z_{B}-z_{A}) = \frac{5}{6}\cdot (x_{C}-x_{A}, y_{C}-y_{A}, z_{C}-z_{A})$

Now, each side of the equation is summed vectorially by $\vec A$ and coordinates of point B are finally found:

$\vec B = \left(x_{A}+\frac{5}{6}\cdot (x_{C}-x_{A}), y_{A}+\frac{5}{6}\cdot (y_{C}-y_{A}), z_{A}+\frac{5}{6}\cdot (z_{C}-z_{A})\right)$

A relish is prepared by the following recipe:

givi [52]

The weight of relish prepared after the evaporation of water is 2,226.02 pounds

<h3>Percentage</h3>

pickles = 1000 pounds
onions = 500 pounds
sugar = 900 pounds
salt brine = 75 pounds
spices = 5 pounds

Total = 1000 + 500 + 900 + 75 + 5

= 2,480 pounds

pickles are 92% water

= 92/100 × 1000

= 920 pounds

onions are 85% water

= 85/100 × 500

= 425 pounds

salt brine is 88% water

= 88/100 × 75 pounds

= 66 pounds

Total water in the mixture = 920 pounds + 425 pounds + 66 pounds

= 1,411 pounds

Percentage of water evaporated = 18%

Amount of water evaporated = 18/100 × 1,411 pounds

= 253.98 pounds

Weight of the relish prepared = 2,480 pounds - 253.98 pounds

= 2,226.02 pounds
