All you have to do is make all of the shapes to rectangles and the count how many is inside and that is the area.
The axis of symmetry of a parabola like
is a vertical line of the form
where k is the x coordinate of the vertex of the parabola.
In particular, the x coordinate of the vertex of the parabola is given by
which in your case becomes
So, the axis of symmetry is the line
Answer:
1 3/8
Step-by-step explanation:
Since 11 is over 8 that means you already have a whole number so you just add the 3 and you get 1 3/8
To check just in case you just multiply the whole number and denominator and then add the numerator.
Since X increases by 1,
Divide the 2nd Y value by the first Y value:
4/6 = 2/3
The answer is 2/3
We know there are no squares between 100² and 101².
So we just want to know how many numbers between a and b exclusive, which is
n = b - a - 1
For example between 10 and 20 exclusive we get n=20-10-1=9, which is right.
For our problem here we can factor using the difference of two squares and get:
n = 101² - 100² - 1 = (101 - 100)(101 + 100) - 1 = 1(201) - 1 = 200
Answer: d. 200
