I believe the answer is the fourth option.
Answer:
4.2 h
Step-by-step explanation:
12 * (50%-15%) = 4.2 h
Answer:
A. Draw a line from the segment to any point on the fold line.
Step-by-step explanation:
When using the paper folding method to find the midpoint of a line segment we take the following steps:
- Draw a line segment on the tracing paper
- Fold the tracing paper so that the endpoints lie on top of each other
- Mark the intersection of the fold and the segment with a point
These steps include statements B, C, and D. Drawing a line from the segment to any point on the fold line, which is statement A, is not included in these steps because it is not needed.
Thus, choice A is not a step in using paper folding to find the midpoint of a line segment.
#Lets just write x as the nunber you asked
x × 40/100 = 18
x = 18 : 40/100
x = 18 × 100/40
y = 1800/40
y = 45

Answer : 45</h3>
The length of a curve <em>C</em> parameterized by a vector function <em>r</em><em>(t)</em> = <em>x(t)</em> i + <em>y(t)</em> j over an interval <em>a</em> ≤ <em>t</em> ≤ <em>b</em> is

In this case, we have
<em>x(t)</em> = exp(<em>t</em> ) + exp(-<em>t</em> ) ==> d<em>x</em>/d<em>t</em> = exp(<em>t</em> ) - exp(-<em>t</em> )
<em>y(t)</em> = 5 - 2<em>t</em> ==> d<em>y</em>/d<em>t</em> = -2
and [<em>a</em>, <em>b</em>] = [0, 2]. The length of the curve is then
