KE=1/2mv^2
50000=(0.5)(1000)v^2
v^2=50000/500
v^2=100
v=10 ms^-1

Answer:

½mv²= KE  

½(1000)?²= 50000

<u>500</u>*?²= <u>50000 </u>

500          500

? ²=100

Square root  

?= 10

Truth statement are statements or assertions that is true regardless of whether the constituent premises are true or false. See below for the definition of Euclidean Postulates.

<h3>What are the Euclidean Postulates?</h3>

The five Euclidean Postulates are;

1. Any two points can be joined by a straight line segment.

2. In a straight line, any straight line segment can be stretched indefinitely.

3. A circle can be formed using any straight line segment as the radius and one endpoint as the center.

4. Right angles are all the same.

5. If two lines meet a third in a way that the sum of the inner angles on one side is smaller than two Right Angles, the two lines will inevitably collide on that side if they are stretched far enough.

The truth statements relating to the attached pictures and their equivalent Euclidean Axiom are;

a) The right angle in the first page of the book shown and the right angles in the last page of the book shown are all the same. (Postulate 4);

b) If the string from the Yoyo dangling from hand in the picture is rotated for 360° such that the length of the string remains equal all thought, and the point from where is is attached remains fixed, it will trace a circular trajectory. (Postulate 3)

c) The swords held by the fighters can be extended into infinity because they are straight lines (Postulate 5)

Write the equation of a line that is parallel to the following:<br><br> 1. x = 5<br><br> 2. y = -3
sineoko [7]

Answer:

1.  x=6

2.  y=2

Step-by-step explanation:

If x=5, the line is vertical, so we need a vertical line so that we are parallel.  A vertical line is x= a constant

We can choose the value for x as long as it is not 5, that would make it the same line.  I will choose x=6

If y=-3=5, the line is horizontal, so we need a horizontal line so that we are parallel.  A horizontal line is y= constant

We can choose the value for y as long as it is not -3, that would make it the same line.  I will choose y=2

How do you solve these linear system of equations by graphing
fenix001 [56]

Answer:Y=-8-2x

Y=-1+1x

Step-by-step explanation:

Solve for y in the second equation

the answer for that should be y= -8-2x and y=-1+1x

then plot both of the equations using rise over one

Suppose why varies directly with X. Write a variation equation that relates x and y
diamong [38]

Answer:

x = y - 6.4

Steps :

1. Create an equation

If x-4=0 and y-10.4=0, then x - 4 = y - 10.4

x - 4 = y - 10.4

2. Isolate variable X by adding 4 to both sides

x = y - 6.4

3. (Optional) Check Answer by plugging given values into the equation

(4) = (10.4) - 6.4

4 = 4 is a true statement

Answer:

4S = 33

Step-by-step explanation:
