Answer:
Option B, - 7 + 12 = 5
Step-by-step explanation:
As you can see, the up line starts from the point 0 and it goes back by seven (- 7). Then from negative seven, it took 12 steps forward to zoom to positive 5 (+ 5). So + 5 is the last result of the process. It took 12 steps forward.
So with these statements kept in mind. Look at the options that would be described by these.
Let's start by this statement: "So + 5 is the last result of the process."
Option B and D only seem to have + 5 as the result.
Next statement: "Then from negative seven, it took 12 steps forward to zoom to positive 5 (+ 5)"
<em>Option B</em> is the most logical answer that is described by the statement.
From negative seven (-7) it took twelve steps forward (+ 12) to positive 5
(= 5)
Let's go ahead and find the volume of a prism, then double the dimensions and see what happens to the volume. Then we can apply it to your volume.
volume of a prism with dimensions 2x2x2
v= 2x2x2 = 8 units^3
Now let's double it
volume of prism with dimensions 4x4x4
v= 4x4x4 = 64 units^3
So we see that by doubling the dimensions we multiply the volume by a factor of 8. Let's do that for your volume, 3.5 m^3
3.5 x 8 = 28 m^3
Since the total is 42 divide by two since they are the same length so it would be 21
I think after the 9th bounce it will lose 90% of its max height
times 40 by 0.9 which will give you 36
then take 36 away from 40 leaving you with 4.
answer = 4ft
