How do you this?? Scientific notation

1 answer:

4 0

So Scientific Notation is a "simplified version" of a number. For example, is your number is 2,345, the scientific notation would be 2.345 * 10³.

If it was 0.023, then the scientific notation would be 2.3 * 10^-2.

Scientific notation is found by moving the decimal place to the left or right, until only one digit is left to the left of the decimal; it has to be greater than 1, but less than ten. If you move the decimal place to the right, it's a negative power of 10. If you move it to the left, it is a positive power of 10.

Hope this helps!

If two solids are similar then, the ratio of their volumes is equal to the cube of the ratios of their corresponding sides. That is,
ratio of volume = (5/3)^3
Simplifying the equation above will give us an answer of 125/27.

Somebody had a seizure while making this question, please help

Check the picture below.

$\textit{area of a regular polygon}\\\\ A=\cfrac{1}{2}asn ~~ \begin{cases} a=apothem\\ n=\stackrel{side's}{number}\\ s=\stackrel{side's}{length}\\[-0.5em] \hrulefill\\ a=7\\ s=8.1\\ n=6 \end{cases}\implies \stackrel{\textit{area of the hexagonal base}}{A=\cfrac{1}{2}(7)(8.1)(6)} \\\\[-0.35em] ~\dotfill$

$\textit{volume of a prism}\\\\ V=Bh ~~ \begin{cases} B=\stackrel{base's}{area}\\ h=height\\[-0.5em] \hrulefill\\ B=\frac{1}{2}(7)(8.1)(6)\\ V=3572.1 \end{cases}\implies 3572.1=\cfrac{1}{2}(7)(8.1)(6)h \\\\\\ 3572.1=170.1h\implies \cfrac{3572.1}{170.1}=h\implies \boxed{21=h}$

well, the length of the tunnel is "h", now two 8 meters cars, that's 8+8=16 meters plus a 3 meter connector between them, that's 16 + 3 = 19 meters, can those two cars connected like so fit inside the tunnel? sure thing, "h" can fit 19 meters just fine.

Write a linear function that passes through (1,5) and (2,15)

Leokris [45]

Simple,

using $\frac{y1-y2}{x1-x2} =m (slope)$

find your slope...

$\frac{5-15}{1-2} = \frac{-10}{-1}=10$

thus, 10=m (slope)

Now, using y=mx+b to find your equation, plug in what you know...

Use any of the 2 coordinates.. (1,5)

5= 10(1)+b

5=10+b
-10 -10

-5=b

Thus, the equation to your line is...

y=10x-5.
