Answer:
I don't know!!!!!!!!!!!!!!!!!!!1
Step-by-step explanation:
So the total value of a triangle is 180°
So when u calculate the missing angle its value is 42°
180°-(60°+78°) = 42°
Correct answer is: F(x)=-x^2-3
Step-by-step explanation:
We are given a function:
The graph of is also shown in the given question figure.
It is a parabola with vertex at (0,0).
Sign of is positive, that is why the parabola opens up.
General equation of parabola is given as:
Here, in G(x), a = 1
Vertex (h,k) is (0,0).
As seen from the question figure,
The graph of F(x) opens down that is why it will have:
Sign of as negative. i.e.
And vertex is at (0,-3)
Putting the values of a and vertex coordinates,
Hence, the equation of parabola will become:
Answer:
3000ft²
Step-by-step explanation:
2cm =5 ft
24 cm = 60 ft
20 cm = 50 ft
Area = 60 *50
= 3000
The length could be 5 and width 3. That would equal 15
