3x3x3x3 = 81
x.x.x.x = x^4
2x2x2x2 = 16
B. 81x^4/16
The answer is A is is the best
n= smallest integer
n+2= middle integer
n+4= largest integer
n + n + 4 = 36
2n+ 4 = 36
2n=32
n= 16 which means that the smallest integer is 16
then you substitute it into the equation for the largest integer
n+4=20
16, 18, 20 is the answer
Answer:
(x-4)^2 + (y-2)^2 = 3^2
or
(x-4)^2 + (y-2)^2 = 9 (simplified if needed)
Step-by-step explanation:
-Equation of a circle is:
where the center is (h, k) and the radius is 
.
-Place the center and the point onto that equation:
-Then, you solve:
-So, the result is:
or
(simplified if needed)
Answer:
A. (8/30)(22/29)(21/28)
Step-by-step explanation:
The key is in reading the question really thoroughly, like, way more than you would expect. The <em>first</em> person is from the group of 8, thus (8/30), but the other <em>two</em> <u>cannot</u> be from the group of 8. 30(students total) minus 8 (the 8 people from science class)=22 (remaining in math). You choose one person who is <em>not</em> from the group of 8, and you are left with 21 other people. The number of students available to be in a group goes down each time: 30 down to 29 down to 28 (the denominators). Kaboom, A. (8/30)(22/29)(21/28).
