Why is it helpful to write a number as a product of primes

1 answer:

5 0

Because if you are multiplying or dividing, you can regroup numbers to make it easy so exg
80 times 45 might look scary but it is really 2 times 2 times 2 times 2 times 3 times 3 times 5 times 5
regroup to make
(2 times 5) times (2 times 5) times (2 times 2 times 3 times 3)=10 times 10 times (6 times 6)=10 times 10 times 36=3600

dividing
188/132
188=2 times 2 times 47
44=2 times 2 times 3 times 11
so it becomes (2 times 2)/(2 times 2) times (47/(3 times 11))=1 times 47/33=47/33

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.
