So first divide the equation on both sides by 3. We get
. Slope-y-intercept form is of the form
. Rearranging
, we get
. Divide by two, we get
, which is of that form.
Graphing: The y intercept is at -2, and the slope is 1/2.
It's probably the first one: "People responded to Earth Day with letters..."
Since it's more of a detail that supports a fact, it's not as important as the other three.
Answer:
Area= 50√3 units^2
Step-by-step explanation:
Given:
In given triangle, there are two sides with length 10√3 and 20 along with angle of 30° between them.
As the given triangle is SAS triangle, we'll use the following formula to calculate its area:
A=1/2absinC
where a= 20
b= 10√3
and c=30°
Now putting values we get:
A=(1/2)(20)(10√3) sin(30)
=100√3(1/2)
=50√3
so the area is 50√3 units^2 !
