Answer:
Option C is correct.
Step-by-step explanation:
We are given that line and line
are parallel to each other.
We have to find value of x.
Measure of given angle = 120°
Clearly from pic,
Given angle and x are interior angles and on the alternate sides.
So using a result of parallel line which says that Alternate interior angles are equal.
So, x = 120°
Therefore, Option C is correct.
Answer:
A
Step-by-step explanation:
The formula used for this type of question is
so as long as you don't change anything else (like r), changing m will increase the force. Both of the last 2 answers look like they might be feasible, but they are not. The attraction increases.
So the answer is A
We are given with a quadratic equation which represents a Parabola , we need to find the vertex of the parabola , But let's recall that , For any quadratic equation of the form ax² + bx + c = 0 , the vertex of the parabola is given by ;
Where , D = b² - 4ac (Discriminant)
Now , On comparing the given equation with ax² + bx + c , we have
⇢⇢⇢ <em><u>a = 1 , b = - 10 , c = 2</u></em><em><u>7</u></em>
Now , Calculating D ;
Now , Calculating the vertex ;
Hence , The vertex of the parabola is at (5,2)
Note :- As the Discriminant < 0 . So , the equation will have imaginary roots .
