Many chemistry conferences have held a 50-trillion angstrom run (two significant figures). how long is this run in kilometers and in miles? (1 å = 1 × 10−10 m)

Since, many chemistry conferences have held a 50-trillion angstrom run.

we have to convert this unit into kilometers and miles.

Let us convert it into kilometers first.

Since, 1 trillion =

So, 50 trillion Angstorm = Angstorm

Since, 1 Angstorm =

So, 50 trillion Angstorm =

=

So, 50 trillion Angstorm = 5km

Now, we will express it into miles

Since, 1 mile = 1.61 km

So, 5 km =

= 3.105 miles

= 3.11 miles

So, 50 trillion Angstorm = 5 km = 3.11 miles

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
