Find the point B on AC such that the ratio of AB to BC is 2:3
Virty [35]

Answer:

B(4, - 3 )

Step-by-step explanation:

We have A(2, - 7) and C(7, 3 )

Using the section formula to calculate the coordinates of B

x_{B} = \frac{3(2)+2(7)}{2+3} = \frac{6+14}{5} = \frac{20}{5} = 4

y_{B} = \frac{3(-7)+2(3)}{2+3} = \frac{-21+6}{5} = \frac{-15}{5} = - 3

Hence B(4, - 3 )

olasank [31]

area = 44.0467 \: cm {}^{2}

<h3>step by step explanation </h3>

● area of regular polygon Formulas ,

⟹a = \frac{l^{2}n}{4tan(\frac{\pi }{n)}}

● now finding the area of regular polygon,

⟹\frac{4 {}^{2} \times 8 }{ 4 \: tan \:  \binom{180}{5} }

⟹a =  \frac{128}{4 \times 0.7265}

⟹a = 44.0467 \: cm {}^{2}

why is it not usually realistic to measure the distance between two points on a map as a straight line? explain.
aksik [14]
The map is a flat schematic of some actual distance, on a map, the distance form point A to point B may well be 10 units say, however, in actuality, if you go and walk from point A to point B, you'd notice that, first off is not a straight line most of the time, and also it may have a slanted or sloped section, and the map is not including that slope or hill, whilst you do have to walk it.

so, adding all the twists and curves along the way and any bumps or slopes, is really not exactly 10 units from A to B.

Please I need help !!!!!
Mama L [17]
The formula is y=0.5m+20

You start (0,20) then for each mile you increase by 0.5.
Or
Since the x axis is by two, then every two miles you increase by 1 mile. So (0,20); (2,21); (4,22); (6,23); (8,24).
