According to the Henderson Hassleback equation
pH = pka+log ([A-]/[HA])
Does that get you started?
That is not the graph pictured in your question now is it? You have the amplitude correct.....but look at the origin....something is amiss there, no?
what can you do to flip a sine wave?
When the ball hits the ground h will be = 0
h(t) = -16t^2 + 64t + 80
0 = h(t) = -16t^2 + 64t + 80 Solve for 't' using Quadratic Formula
One answer provided by the Quad Form will be -1 ......you want the POSITIVE answer for 't'
21 P 3 = 7980
21 x 20 x 19 = 7980 ways
8x = -6 divide both sides of the equation by 8 ....what is your result?
2500 - 3/5 *2500 = $1000 left after gas and room
1/2 of 1000 for food = ........
x + x + 2 = 154
2x = 152
x = 76 x+2 = 78 x+4 = 80
(x+y)(x+y) = x^2 + 2xy + y^2
(x+2y +1)(x+3y)
Average of a group of numbers: add the numbers up (225) then divide by the quantity of numbers (25)
225/25 = average = ........
