The second i think you did good
With graphs on paper you can visually see intersecting lines(one solution), identical lines
(infinite solutions), or parallel lines(no solutions).
This method works best for lines that have integers for solutions. The task of determining rational or irrational solutions from graphs is difficult.
The substitution method usually must be used for equations with higher exponents. The deawback of this method is having to work with fractions.
The elimination method is often the method of choice.
This method however requires that you learn to recognize when the systems produce parallel lines or have equations that represent the same lines.
In the image created, we can see that we can apply sin ∅ = opposite / hypotenuse. the opposite side is the distance between 2 parallel bars and the ∅ is the angle made by the diagonal on top.
Given:
∅ = 60°
Opposite = 9 ft
Hypotenuse = 9 / sin 60 = 10.39 ft
the length of the support AB is 10.39 ft
Answer:
Step-by-step explanation:
We are given that a rectangle in which the equation of one side is given by
We have to find the equation of another side of the rectangle.
We know that the adjacent sides of rectangle are perpendicular to each other.
Differentiate the given equation w.r.t.x
()
Slope of the given side=
When two lines are perpendicular then
Slope of one line=
Slope of another side=
Substitute x=0 in given equation
The equation of given side is passing through the point (.
The equation of line passing through the point with slope m is given by
Substitute the values then we get
Hence, the equation of another side of rectangle is given by
