The equation x squared minus 8x+16 represents the data in the graph because if you use the -b/2a x=4. Then if you plug in the 4 for the x in the equation you would come out with the vertex of (4,0). Hope this helps.
Step-by-step explanation:
distance = 160mile
time =5 hour or 5×60=300 minutes
speed =distance /time
v=160/300
v=0.5334miles per minute
Answers:
120kmh = 72.168mph
50kmh = 31.07mph
Explanation:
This is very simple, just multiply 120kmh by 0.6214 to get 72.168mph. Again multiply 50kmh by 0.6214 to get 31.07mph
Answer:
The first graph.
Step-by-step explanation:
The graph of the function y = 2x + 7, is a straight line because it is a linear function, and has y-intercept of 7 and a slope of 3; so we are looking for a graph that has these characteristics.
From the 4 graphs, we see that the 1st graph has a slope of 3 and a y intercept of 7, and thus it is the correct answer.
Answer:
1379.31meters is the line-of-sight distance from the television camera to the base of the stadium .
Step-by-step explanation:
As given
A blimp provides aerial television views of a tennis game.
The television camera sights the stadium at a 17degrees angle of depression. The altitude of the blimp is 400m.
Now by using the trignometric identity .

As the figure is given below .
Perpendicular = AC = 400 m
Hypotenuse = AB

Putting all the values in the identity .



AB = 1379.31 meters
Therefore the 1379.31 meters is the line-of-sight distance from the television camera to the base of the stadium .
