The purpose of the quadratic formula is to easily obtain the x-coordinate of the vertex's location. The goal is to solve the equation by isolating x on one side of the equation, just like you would any other equation.
In step 7, take the square root of both sides. Note that you must account for the negative side of the square root, so add the +/- to the right side (not necessary for the left side because you want the x to be positive when you are finished, and you still get the same answer even if you assume the left side is negative).
Next, subtract b/2a from both sides and simplify the denominator of the root to be 2a.
Finally combine the terms to have a single denominator.
no they cannot because they would not equal 180 degrees
Answer:
80 cubic units
Step-by-step explanation:
Area for rectangular prism is l*w*h
2*8*5=80
We know that the boxes come in four colors: white, red, green, and blue.
Also, there are 6 boxes of each color, which means that there are 6 white boxes, 6 red boxes, 6 green boxes, and 6 blue boxes.
So there are 24 boxes in total
Next step:
P(receiving a white box for the first pick):
6/24
Because there are 6 white boxes over the total amount of boxes to find the probability
Then,
After picking a first white boxes, now there are only 5 white boxes left without replacing, which lead to there are also 23 boxes in total left
P(receiving a white boxes in second pick):
5/23
As a result, the probability of the first winner receiving a white box and the second winner also receiving a box of the same color is 6/24×5/23=5/92, so the final answer will be B 6/24*5/23. Hope it help!
