<h3>Answers:</h3>
- first box = 0
- second box = 0
- third box = 4
- fourth box = -3
It's not a typo that 0 is written twice.
==============================================================
Explanation:
This is considered a step function because it resembles steps or a staircase. The vertical pieces aren't drawn to allow it to remain a function (or else it fails the vertical line test). Also there should be open holes at each left endpoint.
Recall that any horizontal line has a slope of 0 due to the fact that the rise is 0
slope = rise/run
The rise takes care of the vertical change in position. But if the line doesn't go up or down, then rise = 0 leads to slope = 0.
In short, the slope of each horizontal portion is 0. It doesn't matter which sub-section you focus on.
This is why you'll type 0 into the first two boxes.
------------------
As for the remaining two boxes, you'll be looking where the graph is the highest and the lowest to determine the max and min y values respectively.
We see that y peaks at y = 4 at the very top. So you'll type 4 into the third box.
Furthermore, we see that the lowest part of the graph is when y = -3. Therefore, this is the minimum aka smallest y value and you'll type -3 into the fourth box.
well, first off, let's notice that we have a trapezoid with a rectangle inside it, so the rectangle is really "using up" area that the trapezoid already has.
now, if we just get the area of the trapezoid, and then the area of the rectangle alone, and then subtract that area of the rectangle, the rectangle will in effect be making a hole inside the trapezoid's area, and what's leftover, is the shaded section, that part the hole is not touching.
35.53 is the answer I hoped that helped
Answer:
36.4%
Step-by-step explanation:
You know the most about Kim and Molly, so you should start with them.
Let kim's share = x
Therefore Molly's share = x + 105
Ratio
Kim is to Molly as 2 is 5
2/5 = x / (x + 105)
Solution
Cross multiply
2(x + 105) = 5x Remove the brackets.
2x + 2*105 = 5x Consolidate.
2x + 210 = 5x Subtract 2x from both sides
2x - 2x + 210 = 5x - 2x Reduce like terms.
210 = 3x Divide by 3
210/3 = x
70 = x
Laura's Share.
Kim = x = 70
Molly = x + 105 = 70 + 105 = 175
Kim + Molly + Laura = 385
70 + 175 + Laura = 385 Combine the left side
245 + Laura = 385 Subtract 245 from both sides
Laura = 385 - 245 Combine the right. (Subtract)
Laura = 140
Laura's %
Laura's % = (140 / 385) * 100 = 36.4 to 3 places.
Can you show a clearer picture ??
