Answer:
Step-by-step explanation:
We don't need choices to find out the correct answer. Solve this problem by completing the square. Begin by setting the quadratic equal to 0 and moving over the constant, like this:
and factor out the -1 in front of the x-squared, since the leading coefficient HAS to be a 1:
Now take half the linear term, square it, and add it to both sides. Our linear term is -2. Half of -2 is -1, and squaring that gives us 1. So we add a 1 into both sides. But that -1 out front there on the left is a multiplier, so what we actually added in was -1(1) which is -1:
On the left side we have a perfect square binomial, which is why we do this, and on the right side we have -2:
and we can move that constant back over and set the quadratic back equal to y:
which gives us a max height of 2.
(If this was modeling parabolic motion, we would know that the time it takes to get to that max height is 1 second. The vertex of this parabola is (1, 2))
Answer:
y ≤ -1/3x + 1
Step-by-step explanation:
find the slope and y-intercept and write equation in form of
y = mx + b; m = slope and b = y-intercept
if you start at (0,1) and move down and to the right to (3,0) you get a slope equal to -1/3
we can see by looking at the graph that the y-intercept is 1
therefore, y ≤ -1/3x + 1

The correct question is
<span>Four people are painting a house. Max paints 1/8 of the house, Shen paints 14%, Jake paints 0.12, and Todd paints 0.2. Which choice lists the people in order from least to greatest by the amount each one paints the house?
</span>
step 1
convert their contribution to percents
Max paints 1/8------> 0.125-------> 12.5%
Shen paints 14%
<span>Jake paints 0.12-------> 12%
</span>Todd paints 0.2--------> 20%
step 2
List of least to greatest by the amount each one painted the house:
Jake, Max, Shen, Todd.
the answer is
[Jake, Max, Shen, Todd]
