Answer:
The center is at (2.5, -5.4) and the radius is 1.1
Step-by-step explanation:
The formula for a circle is
(x-h)^2 + (y-k)^2 = r^2
Where (x,k) is the center and r is the radius)
(x − 2.5)^2 + (y + 5.4)^2 = 1.21
(x − 2.5)^2 + (y - - 5.4)^2 = 1.1^2
The center is at (2.5, -5.4) and the radius is 1.1
Answer:
Yes, i do belive this is correct
You find the probability of an event happening if you divide the number of times that event has actually happened in the experiment by the number of total events that has happened. If you want to find the probability of the used car, you have to know..
how many used cars were there? 15
how many cars were there? 40
Therefore, the probability of buying a used car is 15/40 or 3/8.
Answer:
Step-by-step explanation:
Notice that angles <1 and <3 are opposed by the vertex, which makes them of equal measure, therefore, <1 = 47 degrees.
Notice as well that angles <1 and <2 combine into a straight line, therefore, they are supplementary angles whose addition gives 180 degrees then we can find the value of angle <2 via:
And finally, angle <4 is opposite through the vertex to angle <2, and therefore they must have the same measure. So, <4 = 133 degrees.
