Answer:

  (6.2, 4.5)

Step-by-step explanation:

We want, for some point P, ...

  (P -A) / (B -P) = 1 / 3

  3(P -A) = (B - P) . . . . . multiply by 3

  4P = B +3A . . . . . . . . add P+3A

  P = (B +3A)/4 . . . . . . .divide by 4

Filling in the coordinate values, we can find P to be ...

  P = ((2.3, 5.4) +3(7.5, 4.2))/4 = (2.3+22.5, 5.4+12.6)/4

  P = (6.2, 4.5)

Solution

In order to find  greatest to least number, we have to convert the given fractions into decimals.

3 \frac{1}{10} % = 3 + 1/10 = 3 + 0.10 = 3.10%

3 \frac{2}{5}% = 3 + 2/5 = 3 + 0.40 = 3.40%

3 \frac{1}{4} %= 3 + 0.25 = 3.25%

3 \frac{1}{3}% = 3 + 0.33 = 3.33%

Now we can easily, compare the numbers and write from greatest to least.

3.40%, 3.33%, 3.25%, 3.10%

Greatest to least  = 3 2/5%, 3 1/3%3, 3 1/4%,  1/10%,

Thank you :)

Select a setting so that each given point will lie within the viewing window.
NemiM [27]

Answer:

The given points are

(-13,3)\\(0,0)\\(-2,-7)

The setting would have a interval or 2 units above and below the minimum and maximum of each coordinate.

The given maxium horizontal coordinate is 0.

The given minimum horizontal coordinate is -13.

The given maximum vertical coordinate is 3.

The given minimum vertical coordinate is -7.

Now, we extend each maximum and minimum value by 2 units to create the setting.

So, the setting is

x_{min}=-15\\x_{max}=2\\ y_{min}=-9\\y_{max}=5

With a scale of 2 units.

What is the square root of 1000/100000
Mrac [35]
Remember that \sqrt{\frac{x}{y} }= \frac{ \sqrt{x} }{ \sqrt{y} } so
\sqrt{\frac{1000}{100000} }= \frac{ \sqrt{1000} }{ \sqrt{100000} }
find the individual square roots
\frac{ \sqrt{1000} }{ \sqrt{100000} }=\frac{ 10\sqrt{10} }{ 100\sqrt{10} } = \frac{10}{100} times \frac{ \sqrt{10} }{ \sqrt{10} }  = \frac{10}{100}   times 1= \frac{1}{10}

answer is 1/10
