Answer:
Step-by-step explanation:
We are given the diameter of the circle. By definition, the diameter goes through the circle right at its center. We can use the midpoint formula to find the center of the diameter which will give us the center of our circle.
which simplifies to
which gives us the midpoint
M = (-10, 1) That's the h and k of our center. We will use that along with one of the given points to solve for r. Plugging into the standard form of a circle (which I'm assuming you know):
and
so
Now we'll use that with the center we found and write the equation:
That's choice B
Answer:
Yes
Step-by-step explanation:
-8x-2y<6 (I prefer to convert this into standard form y=mx+b)
-8x+8x-2y<8x+6
-2y/-2>8x+6/-2
y > -4x -3
2 > -4(3) - 3
2 > -12 - 3
2 > -15 True or Yes
Answer:
53 1/3% for the first answer, and 33 1/3% increase for the second answer
Step-by-step explanation:
Ok, lets start up witht eh first question.
We need to find the percentage of studens that find math the be their favorite subject in elementary school.
We know that there are 15 kids in total.
We specificly see that 8 of those kids like math the most.
To find percentage, divide 8 by 15.
Using a calculator you should find 53 1/3% of the students found math to be their favorite subject.
Next we need to find the percentag eof change that history is over elementary school to high school.
This might sound confusing, but this is basically just a change of 3 students to 4 students.
To find percentage, just divide 3 by 4:
This gets you 33 1/3%
Hope this helps!
I'm thinking its 4 to the 12 power but I am not completely sure on this
