How to prove points belong to the same circle

Mathematics

kenny6666 [7]3 years ago

Not sure what the mess above me says, but basically as long as you have an equation for the circle, you can plug the coordinates of your point into the x and y values of the equation and see if it equals out. If you don’t have an equation, you can just make one. Use (f-k)^2+(x-h)^2=r^2 where h and k are the coordinates of the center of the circle and r is the radius. Hope this helps!

guapka [62]
If each slice turns a right angle that means it turns 90* so you can only have two turns per pizza which gives 4 slices (90+90+90+90=360 - this is how many degrees in a circle) so per pizza 4 slices. For four pizzas that is 4x4 which is 16 so 16slices

Mkey [24]

Answer:

  4π in ≈ 12.57 in

Step-by-step explanation:

One full revolution (2π radians) is made in 60 minutes. In 40 minutes, the hand moves through an angle θ of (40/60)(2π) = 4π/3 radians. The length of the arc is ...

  s = rθ = (3 in)(4π/3) = 4π in ≈ 12.57 in

How many different ways are there to arrange the letters of the word PRISM?
Advocard [28]

Answer:

5! (5 factorial) or 120 ways

Step-by-step explanation:

You can arrange P different ways. R can be arranged only 4 different ways because Pwill be in one of the spots. Next, you can arrange "I" 3 different ways because P and R are already arranged in 2 spots, meaning you cant put "I" there. Next, S can be arranged in 2 different ways for the same reason. And lastly, M can only be arranged in 1 different way because the other spots are taken.

You can put it in any order. For example, M could be arranged 5 ways and P could be arranged in 1 way. You will still get 120 ways

Hopefully this helped. The explanation might be a bit confusing but I tried my best. I'm not good with explaining my solutions but I always try
