Step-by-step explanation:
<u>Quadratic equation</u>
The quadratic equation can be written in several ways, one of the most-used is
To rewrite the equation in the form
we can complete squares and rearrange the terms as follows. The provided equation is
The second term can be seen as
And the first two terms can be visualized as the square of a binomial
We have added and subtracted 81 to complete the square and not modify the equation. The new form of the equation is
Rearranging
Comparing with the general form written above, we find that
Answer:
Option 2: -¾
Step-by-step explanation:
First identify 2 points on the line.
(0, 1), (4, -2)
Substitute the coordinates into the gradient formula below:
☆ (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate.
Slope of the line
☆ Since the line is sloping downwards looking from the left to right, the line must have a negative slope.
Answer:
The co-ordinates of the other corner of this side which is 3 meter from the edge is (3,3)
Step-by-step explanation:
Given
One corner of the solar panel is (3,6)
The co-ordinates of the other corner of this side which is 3 meter from the edge is
X co-ordinates = 3
Y co-ordinates = 6-3 = 3
The co-ordinates of the other corner of this side which is 3 meter from the edge is (3,3)
Plane
Plane is an undefined geometric term possessing 2 dimensions; Length and width.
Planes extend infinitely therefore if has no beginning nor end.
