Answer:
The axis of symmetry is on x = 1
Step-by-step explanation:
When you graph the function, the vertex is at (1,-4). This means that the axis of symmetry is at x = 1
If this answer is correct, please make me Brainliest!
Step-by-step explanation:
It cannot be (4, -3) as there would be 2 outputs (3 and -3) for the input 4, therefore it becomes a one-to-many relationship and not a function.
Answer:
0.675 m/s
Step-by-step explanation:
Let height of shadow= y,CD=x
Height of man=2 m
Speed of man= 
Therefore, 
Differentiate w.r.t t
When the man is 4 m from the building
Then, we have x=12-4=8 m
Substitute the values in above equation then, we get
Substitute the values then we get
Hence, the length of his shadow on the building decreasing at the rate 0.675 m/s.
Answer:
x = (74-28)/2
Step-by-step explanation:
We find the perimeter of a triangle by adding the sides together
s1 +s2+s3 = P
The perimeter is 74
s1 +s2+s3 = 74
We know one of the sides is 28
28 +s2+s3 = 74
The other two sides are equal in length, call them x
28 +x+x = 74
Combine like terms
28+2x = 74
We want to solve for x
Subtract 28 from each side
28-28+2x = 74-28
2x = 74-28
Divide each side by 2
2x/2 = (74-28)/2
x = (74-28)/2
It's 3, I believe. Divide both point "A"'s buy each other
