The only one that doesn’t equal to 1 is 12/4-11/9
Answer:
With this sort of geometric problem, all you need to do is look and identify, to narrow down your answer. Particularly, you should pick up on any trends. I'm hoping you noticed that using the other two points, you can see that they are dividing by three from the red shape to get the blue shape sides. And you should also notice that the shape is flipped, so if you picture it in the same position as the other one to match up the sides!
To find n, simply do 6 ÷ 3
This equals 2!
Answer:
Step-by-step explanation:
The vertex form of a parabola is given by y = a(x - h)^2 + k, where (h, k) is the vertex.
Given vertex at (2,-3), h = 2, k = -3
y = a(x - 2)^2 + (-3) = a(x - 2)^2 - 3
The parabola passes through (0,5) so
5 = a(0 - 2)^2 - 3
5 = 4a - 3
4a = 8
a = 2
The parabola equation in vertex form:
y = 2(x - 2)^2 - 3
Step-by-step explanation:
the answer is
a= 2
b=3
c= 8
<u>Given</u>:
The given circle with center at C. The lines AB and AD are tangents to the circle C.
The length of AB is (3x + 10)
The length of AD is (7x - 6)
We need to determine the value of x.
<u>Value of x:</u>
Since, we know the property of tangent that, "if two tangents from the same exterior point are tangent to a circle, then they are congruent".
We shall determine the value of x using the above property.
Thus, we have;
AB = AD
Substituting the values, we get;
Subtracting both sides of the equation by 7x, we get;
Subtracting both sides of the equation by 10, we get;
Dividing both sides of the equation by -4, we get;
Thus, the value of x is 4.
