DENIUS [597]

Answer:

The difference in finishing time between the 2nd and 3rd places is the shortest and it is 0.07 seconds.

Step-by-step explanation:

The first positioned swimmer took 55.98 seconds and the second positioned swimmer took 56.87 seconds to complete the race.

So, the difference is (56.87 - 55.98) = 0.89 seconds.

The second positioned swimmer took 56.87 seconds and the third positioned swimmer took 56.94 seconds to complete the race.

So, the difference is (56.94 - 56.87) = 0.07 seconds.

The third positioned swimmer took 56.94 seconds and the fourth positioned swimmer took 57.17 seconds to complete the race.

So, the difference is (57.17 - 56.94) = 0.23 seconds.

The fourth positioned swimmer took 57.17 seconds and the fifth positioned swimmer took 57.27 seconds to complete the race.

So, the difference is (57.27 - 57.17) = 0.10 seconds.

The fifth positioned swimmer took 57.27 seconds and the sixth positioned swimmer took 57.35 seconds to complete the race.

So, the difference is (57.27 - 57.35) = 0.08 seconds.

Therefore, the difference in finishing time between the 2nd and 3rd places is the shortest and it is 0.07 seconds. (Answer)

The circle below has a center O, and A and C are points on the circle. Use this circle to answer questions 1 – 3.

wlad13 [49]

Given:

Center of the circle is O.

A and C are points on the circle.

Solution:

Question 1.

The piece of the circle between the points A and C is called an arc.

Question 2.

AOC is a acute angle. It is located in a center of the circle.

Therefore AOC is a central angle.

Question 3:

The line segment joining center to boundary of the circle is called the radius.

Therefore the line segment OC is a radius of the circle.

What are the rotations that will carry this equilateral triangle onto itself?

Studentka2010 [4]

The rotations that will carry the equilateral triangle in discuss onto itself are;

90° counterclockwise rotation about its center P.
270° counterclockwise rotation about its center P.

<h3>Which rotations will carry this equilateral triangle onto itself?</h3>

It follows from the task content that the rotation which produces the desired output in which case, the rotation maps exactly unto the equilateral triangle is required.

On this note, when the rotation is 90° and 270° about the center P in which case, the rotation can be clockwise or anticlockwise, the desired result is obtained.

(h) when is the particle speeding up? (enter your answer using interval notation.) (2,4)∪(6,8) incorrect: your answer is incorre

OverLord2011 [107]

The position of the particle as function of time is given as
$f(t)=cos( \frac{\pi t}{4} )$

The velocity as function of time is
$v(t)= - \frac{\pi}{4} sin( \frac{\pi t}{4} )$

A graph of f(t) versus t and of v(t) versus t is shown below.
The velocity increases in the intervals t = (2, 6) and t = (10, 14) and with a periodicity of 8.

In the range t = [0, 16], the velocity increases in the interval t = (2,6)∪(10, 14).

Answer: (2,6)∪(10,14)
