IceJOKER [234]

Answer:

Since I cant say which answer due to no graph, I'll tell you How to do so.

Step-by-step explanation:

if it is A, then the there is at least one angle or line length that is not the same. To find the area of a grided shape, use the traingle theorm of a^2+b^2=c^2.

if it is B, that meants moving the shape to the other will result in a perfect fit. Be sure to find if all side lengths are the same as that means that the shape IS congrouent, as equal side length means equal angles. However, it will not be this choice if the shape is mirrored to the other

A rotation and tranlastion means it is flipped either upside down or up and moved to the shape.

D, a reflection, which means its the opposite. Like a mirrored shape. Then you move it.

gtnhenbr [62]

Answer:

The concentration of hydrogen ions in moles per liter (M) is 3.981 * 10^{-9}

Step-by-step explanation:

As we know

The hydrogen ion concentration of any solution at pH is given by

H^+ = 10^{-pH}

Substituting the given values in above equation, we get -

H^+ = 10^{-8.4}\\H^+ = 3.981 * 10^{-9} mol/l

The concentration of hydrogen ions in moles per liter (M) is 3.981 * 10^{-9}
