Answer:
Step-by-step explanation:
The last (fourth) graph is that of the parent function y = √x. The negative sign in front of √x leads to reflection of this parent function graph in the x-axis. Thus, the correct graph of f(x) = -√x is the first one.
Answer:
midpoint: (7.5, 1.5)
Step-by-step explanation:
midpoint formula: ( (x1 + x2)/2 , (y1 + y2)/2 )
x1= 10
x2= 5
y1=1
y2=2
( 10 + 5 )/2 = 7.5
( 1 + 2 )/2 = 1.5
midpoint coordinates => ( 7.5 , 1.5 )
Fist we find the legnth of the diagonal
a^2+b^2=c^2
3^2+4^2=c^2
9+16=c^2
25=c^2
c=5
now the other diagonal
11^2+5^2=c^2
121+25=c^2
146=c^2
sqrt both sides12.083
closest is B
The best estimate would be D: 331 km
