Yes, it is true. Divide them and you get 12/30=.4 and 20/50=.4.
1,2,3,4,6,9,12,18 and 36. 1,2,3,6,9,18,27, and 54 .Although the numbers in bold are all common factors of both 36 and 54 ,18 is the greatest common factor. The second method to find the greatest common factor is to list the prime factors, then multiply the common prime factors
2y(x3+9x-10x2-45) not much to be taken as a common factor
Every line from the tangent to the centre is 90°. This is said in the circle theorems.
So angle OBC and ODC are 90°.
angle O is twice the size of angle F. This is another circle theorem.
Therefore angle O is 152°.
The quadrilateral of ODBC would equal to 360°. Which means 90° + 90° + 152° = 332°
360° - 332° = 28°.
The answer is 28°
The value of a is 1/4 and the value of h and k is (2,-7/4)
<h3>What is a Parabola ?</h3>
A parabola is a u shaped curve. It is a plane curve whose all points are at a fixed distance form a point called focus.
(x-h)² = 4a(y-k)
It is given that the parabola goes through the point (3, -1), and the vertex is at (2, -2).
Therefore
(x -2)² = 4a(y +2)
The parabola passes through the point (3,-1)
(3-2)² = 4*a(-1+2)
1 = 4 a
a = 1/4
Now to determine the value of focus point , (h,k)
(h = 2)
k = - 2 +1/4 = -7/4
Therefore The value of a is 1/4 and the value of h and k is (2,-7/4)
