given that - 1 hour = 60 min
then, 25 60
then, we cut it from the table of 5 !!
therefore, 5:12
2, the answer is 2 guys, minimum not maximum no infinity!
Answer:
Circumcenter = (4,0)
Circumcircle = √5
Step-by-step explanation:
The circumcentre is the point of intersection of the perpendicular bisectors of a triangle. The vertices of the triangle are equidistant to the circumcentre.
Let us assume the coordinate of the circumcentre is at O(x, y). Therefore the distance between the cirmcumcenter and the vertices are:
AO = BO, therefore
√(x² + y²-4x-2y+5) = √(x² + y² - 10x - 4y + 29)
x² + y²-4x-2y+5 = x² + y² - 10x - 4y + 29
6x + 2y = 24 (1)
BO = CO
√(x² + y² - 10x - 4y + 29) = √(x² + y² - 9x - 8y + 25)
x² + y² - 10x - 4y + 29 = x² + y² - 9x - 8y + 25
-x + 4y = -4 (2)
Multiply equation 2 by 6 and add to equation 1:
26y = 0
y=0
Put y = 0 in -x + 4y = -4
-x + 4(0) = -4
x = 4
The cicumcenter is at (4, 0)
The radius of the circumcircle = AO = BO = CO. Therefore:
Answer:
The bowling ball have more gravitational potential energy as it sit on top of the building
Step-by-step explanation:
The law of conservation of energy. The energy due to work performed on the skateboarder is converted into kinetic energy such that:
Work=Kinetic Energy
So 380=(1/2)(35)(7-Vo). I don’t have a calculator so..
Assumptions we made:
No energy loss, all work went into the energy of motion of the skateboarder. In the real world, this is not possible because some of the energy can be loss through friction of the skateboarder to the ground etc.
