What should you multiply if you change centimetres to millimetres

Mathematics

vova2212 [387]3 years ago

Answer:

  10 mm/cm

Step-by-step explanation:

The conversion factor always has a value of 1. It is a fraction with the numerator equal to the denominator -- only the units are different.

The numerator units are the units you're converting <u>to</u>: millimeters. The denominator units are the units you're converting <u>from</u>: centimeters.

You know that 1 cm = 10 mm, so when you arrange the fraction as described, the conversion factor you're multiplying by is ...

  \boxed{\dfrac{10\,\text{mm}}{1\,\text{cm}}}

Simora [160]

Answer:

1+r+r^{2}+r^{3}+.....+r^{n-1} = \frac{1-r^{n}}{1-r}

Step-by-step explanation:

Taking the succession:

1+r+r^{2}+r^{3}+.....+r^{n-1}

You can multiply and divide by 1-r without chaging the result:

\frac{1-r}{1-r} (1+r+r^{2}+r^{3}+.....+r^{n-1})

Distributing the upper part of the fraction you have:

\frac{1}{1-r} (1-r+r-r^{2}+r^{2}-r^{3}+r^{3}-r^{4}+.....+r^{n-1}-r^{n})

As can be seen all the intermediate members will be canceled by a same member with opposite sign, only (1-r^{n}) will be left so:

1+r+r^{2}+r^{3}+.....+r^{n-1} = \frac{1-r^{n}}{1-r}

denis23 [38]

Answer:

The parabola generated by the expression :

y=x^2-2x+3

is the one that better represents a rain gauge above the ground.

Step-by-step explanation:

The function:

a) y=x^2+11x+24

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: below

So, the parabola doesn't depict a rain gauge off the ground

b) y=-x^2-6x-8

Direction of parabola: branches pointing down

Location of vertex relative to x-axis: above

So, the parabola doesn't depict a rain gauge off the ground

c) y=x^2-2x+3  

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: two units above

So, the parabola depicts a rain gauge off the ground

d) y=x^2+4x+4

Direction of parabola: branches pointing up

Location of vertex relative to x-axis: right on the x-axis

So, the parabola doesn't depict a rain gauge off the ground (this is sitting on the ground)

e) y=3x^2+21x+30

Direction of parabola: branches pointing up

Location of vertex relative to x-axis:  below

So, the parabola doesn't depict a rain gauge off the ground
