To calculate hydronium concentration from pH, type on you calculator
10 to the power of negative pH value
10^-5.5 = 3•10^6 mol/L
Since there are 3 hydrogens in every hydronium molecule,
There are 9 • 10^6 hydrogens in that liter of acid.
Answer: 5
Step-by-step explanation:
This is your generic run-of-the-mill sinusoidal function:
f(x) = sin(x)
This is the same sine function but with a phase shift of 3 units to the right:
f(x) = sin(x-3)
This is the sine function but with an amplitude of 4 units:
f(x) = 4sin(x)
This is the sine function but flipped across the x-axis:
f(x) = -sin(x)
Combine all these transformations to get:
f(x) = -4sin(x-3)
Answer:
M < P < N
Step-by-step explanation:
Greater angles oppose sides of greater length.
Answer:
Slopes of parallel lines are equal
Step-by-step explanation:
On a coordinate plane, quadrilateral ABCD is shown. Point A is at (-2, -2), point B is at (-3, 4), point C is at (2, 2), and point D is at (3, -4).
The slope of the line segment BC is:
![\dfrac{4-2}{-3-2} =-\dfrac{2}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7B4-2%7D%7B-3-2%7D%20%3D-%5Cdfrac%7B2%7D%7B5%7D)
The slope of the line segment AD is:
![\dfrac{-4-(-2)}{3-(-2)} =\dfrac{-4+2}{3+2}=-\dfrac{2}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7B-4-%28-2%29%7D%7B3-%28-2%29%7D%20%3D%5Cdfrac%7B-4%2B2%7D%7B3%2B2%7D%3D-%5Cdfrac%7B2%7D%7B5%7D)
The slope of the line segment CD is:
![\dfrac{2-(-4)}{2-3} =\dfrac{2+4}{2-3}=\dfrac{6}{-1}=-6](https://tex.z-dn.net/?f=%5Cdfrac%7B2-%28-4%29%7D%7B2-3%7D%20%3D%5Cdfrac%7B2%2B4%7D%7B2-3%7D%3D%5Cdfrac%7B6%7D%7B-1%7D%3D-6)
The slope of the line segment BA is:
![\dfrac{4-(-2)}{-3-(-2)} =\dfrac{4+2}{-3+2}=\dfrac{6}{-1}=-6](https://tex.z-dn.net/?f=%5Cdfrac%7B4-%28-2%29%7D%7B-3-%28-2%29%7D%20%3D%5Cdfrac%7B4%2B2%7D%7B-3%2B2%7D%3D%5Cdfrac%7B6%7D%7B-1%7D%3D-6)
Because the slopes of parallel lines are equal. Therefore, ABCD is a parallelogram because both pairs of opposite sides are parallel.
