The graph shows the function f(x) = |x – h| + k. What is the value of k? k = –2.5 k = –A. k = –2.5
2 answers:
k is the y-coordinate of the vertex of the function. That vertex is located at (1, -2.5).
The value of k is ...
... A. k = -2.5
Answer:
k=-2.5
Step-by-step explanation:
Given is a graph V shaped two straight lines symmetrical about x=1
Hence the function willbe of the form
To find k
When x=1, we find the graph has a minimum at (1,-2.5)
Substitute x=1 to find f(1)
f(1) = |1-1|+k=0+k=k
Since f(1) = -2.5 from the graph we have
k =-2.5

Sol'n
Here,
km=82=82000miles
m=?
Now,
Miles =km×1000
=82×1000
=82000
Therefore,82000m.
Answer:
Max and Elena live 5764 miles away from each other.
Step-by-step explanation:
One mile is equivelant to 1.6 kilometers.
That is correct.
Sqrt 5 x sqrt20
Apply the radical rule to get sqrt( 5 x 20)
Simplify to get sqrt(100)
Sqrt(100) = 10
Answer:
82.72m
Step-by-step explanation:
Volume = πr2h
= 3.142*7*7*14
= 2,155.41m³
Now that we hav the volume of earth, we go on to find the raduis of the spread
2155.41m³ = 3.142*r²*0.4
2155.41m³ = 1.26r²
r² = 1,710.64
r = 41.36m
Width = diameter = 2r = 82.72m
