Answer:
Step-by-step explanation:
If it is a parallelogram the opposite sides will a have the same slope.
Using the diagram we see from the coordinates of A and B:
Slope of AB = (5 - -1)/(-1 - -5)
= 6/4
= 3/2.
In the same way
slope of CD = (2 - -4) / (1 - -3)
= 3/2.
So AB and CD can be shown to be parallel.
Similarly the lines BC and AD are parallel.
So the figure is a parallelogram
Finding the perimeter (counting the units between the points):
Perimeter = 2AB + 2BC
By Pythagoras:
AB = sqrt (6^2 + 4^2) = sqrt 52
BC = sqrt (3^2 + 2^2) = sqrt 13
So Perimeter = 2sqrt52 + 2sqrt13
= 4sqrt13 + 2 sqrt13
= 6sqrt13
or 21.63 unit^2 to 2 decimal places.
Area = sqrt52 * perpendicular distance between the lines AB and CD.
Answer:
I'd need to see more, but because they are the same number just positive and negative they'd be on opposite ends of zero
Answer:
g(x) = 5x + 2.
r(x) = x
b(x) = 1/2 x³
k(x) = - 3 x + 1
Step-by-step explanation:
The function notation ⇒ it is the form to write the function, It is meant to be a precise way of giving information about the function, like f(x) , v(x) and so on.
Given the following:
g(x) = 5x + 2.
y = 1 x
h = x²
r(x) = x
f/x = x⁵ - 3
b(x) = 1/2 x³
p/x = -7x
k(x) = - 3 x + 1
y = mx + b
fx = -x³ + 4
So, in the given options the following are in function notations:
g(x) = 5x + 2.
r(x) = x
b(x) = 1/2 x³
k(x) = - 3 x + 1
