Answer:
Step-by-step explanation:
we know that
The Pythagorean Theorem states that in a right triangle
where
c is the greater side (the hypotenuse)
a and b are the legs
In this problem
Let
c=AB ---> distance from point A to point B
a ---> the difference of the x-coordinates both points
b ---> the difference of the y-coordinates both points
so
substitute
604700.
604703.472883
= 604700.
The tens digit is 0 so the hundreds digit (7) stays the same.
see explanation
For the ellipse
+ = 1
Then the vertices are (a, 0), (- a, 0) and (0, b), (0, - b)
Given
Then
a² = 4 ⇒ a = 2 and b² = 100 ⇒ b = 10
Hence the vertices are
(2, 0), (- 2, 0) and (0, 10), (0, - 10)

c. about the origin
The function is odd: replacing x with -x gives the negative of the function value:
f(-x) = -f(x)
Odd functions are symmetrical about the origin.
-4/3
-3 x (-2/3)²
= -3 x (4/9)
= -4/3
