The actual distance between the cities is 50 miles
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:
Step-by-step explanation:
We need to compare √8 and 4
<em>To compare the numbers they should both be in the same format</em>
<u>√8 is not a perfect square so we'll put number 4 under root</u>
<u>Now we compare</u>
So √8 is less than 4
We are given that:
The skateboard park is located at the point (-3,5),
the ice cream shop is located at the point (-3,6),
and the comic book store is located at (4,6).
We are also given that the four coordinates forms a rectangle.
Here we already have two matching x- coordinates as -3 and y coordinates as 6.
Now we must have two matching x and y coordinates too.
As shown in figure , if we have the last coordinate as (4,5), it will complete the rectangle.
So answer is option B) (4,5) is the last coordinate at which his best friend lives.
