What is 7.86 x 10 to the negative 2nd power kL in dL?
ELEN [110]
So a kiloliter (kL) is 1000 liters, while a deciliter (dL) is 0.1 liters.

You have 0.0786kL, or 78.6L.

78.6L is equal to 786dL.

Envision this as a right triangle, with one leg of 12 miles, and the other 16 miles. Solve using the Pythagorean Theorem a²+b²=c²:

12²+16²=c²
400 = c²
20=c...they live at least 20 miles from each other.

The graph of the logarithmic function f(x) = loga(x) passes through the points and . The graph lies the y-axis.
vagabundo [1.1K]
The question is incomplete. But this explanation will help you very much.

1) Regarding the function      log_ax   , its graph always passes through the points (1,0) and (a,1).

That is due to the properties of logarithm function:

a)    log_a1=0

b)    log_aa=1
<span> 
That in turn is due to the properties of the exponential functions.

a^0 = 1 and a^1 = a
</span>
2) Regarding the y-axis.

The function log_ax will never touch the y-axis, because the logaritm of zero is not defined. So the graph lies to the righ of the y-axis (i.e. the domain of the function is x > 0)
