Answer:
The square root of 48 is the only irrational number in that group.
Step-by-step explanation:
A. 26.6 ( repeating 6 ) =
B. = 4√3
C. -51/2 = -25.5 =
D. -55.1
So, we have A, C and D as rational numbers.
Only is an irrational number
Hence, The square root of 48 is the only irrational number in that group.
Answer:
+ 24x + 16
Step-by-step explanation:
If it is a square, all sides are equal. An area of a square would be side x side. You would multiply 3x + 4 and 3x + 4 together. I used the foil method (multiply first, then outside, inside, last) or (3x * 3x, 3x * 4, 4 * 3x, 4 * 4).
Answer:
Step-by-step explanation:
Consider a sketch of the problem as shown in the picture, where:
Since the center of the circle lies on the line y = 4x +1 and is tangent to the x-axis at point A, then its radius BA is perpendicular to the x-axis. To find the coordinates of point B, we must replace x = -3 into the blue line equation: y = 4x(-3) + 1 = -11.
So, we know that the center of the circle is at B=(-3, -11). And furthermore, the radius BA is of length r=11.
Since the <em>general equation of the circle</em> of radius lenght r centered at (h, k) is given by
then with h = -3, k = -11 and r= 11, the equation of our circle is
